 Release Notes

+==========================
+
+Release Notes
+*************
+
+v2.2.7 released 2014-02-20
+==========================
+
+Percona Toolkit 2.2.7 has been released. This release has only one bug fixed. 
+
+* Fixed bug 1279502: --version-check behaves like spyware
+
+  The configuration for what information PT tools should collect was not hardcoded in the scripts. Instead, every time it's downloaded from http://v.percona.com/. One of the possible parameters was a binary file name to be executed. This was fixed by removing the remote execution.
+
+Percona Toolkit packages can be downloaded from http://www.percona.com/downloads/percona-toolkit/ or the Percona Software Repositories (http://www.percona.com/software/repositories/).
+
+v2.2.6 released 2013-12-18
+==========================
+
+Percona Toolkit 2.2.6 has been released. This release has 16 bug fixes and a few new features.  One bug fix is very important, so 2.2 users are strongly encouraged to upgrade:
+
+* Fixed bug 1223458: pt-table-sync deletes child table rows
+
+Buried in the pt-table-sync docs is this warning:
+
+  Also be careful with tables that have foreign key constraints with C<ON DELETE>
+  or C<ON UPDATE> definitions because these might cause unintended changes on the
+  child tables.
+
+Until recently, either no one had this problem, or no one reported it, or no one realized that pt-table-sync caused it.  In the worst case, pt-table-sync could delete all rows in child tables, which is quite surprising and bad.  As of 2.2.6, pt-table-sync has option --[no]check-child-tables which is on by default.  In cases were this "bug" can happen, pt-table-sync prints a warning and skips the table.  Read the option's docs to learn more.
+
+Another good bug fix is:
+
+* Fixed bug 1217013: pt-duplicate-key-checker misses exact duplicate unique indexes
+
+After saying "pt-duplicate-key-checker hasn't had a bug in years" at enough conferences, users proved us wrong--thanks!  The tool is better now.
+
+* Fixed bug 1195628: pt-online-schema-change gets stuck looking for its own _new table
+
+This was poor feedback from the tool more than a bug.  There was a point in the tool where it waited forever for slaves to catch up, but it did this silently.  Now the tool reports --progress while it's waiting and it reports which slaves, if any, it found and intends to check.  In short: its feedback delivers a better user experience.
+
+Finally, this bug (more like a feature request/change) might be a backwards-incompatible change:
+
+* Fixed bug 1214685: pt-mysql-summary schema dump prompt can't be disabled
+
+The change is that pt-mysql-summary no longer prompts to dump and summarize schemas.  To do this, you must specify --databases or, a new option, --all-databases.  Several users said this behavior was better, so we made the change even though some might consider it a backwards-incompatible change.
+
+Percona Toolkit packages can be downloaded from http://www.percona.com/downloads/percona-toolkit/ or the Percona Software Repositories (http://www.percona.com/software/repositories/).
+

+
+v2.2.5 released 2013-10-16
+==========================
+
+Percona Toolkit 2.2.5 has been released. This release has four new features and a number of bugfixes.
+
+Query_time histogram has been added to the pt-query-digest JSON output, not the actual chart but the values necessary to render the chart later, so the values for each bucket.
+
+As of pt-table-checksum 2.2.5, skipped chunks cause a non-zero exit status. An exit status of zero or 32 is equivalent to a zero exit status with skipped chunks in previous versions of the tool.
+
+New --no-drop-triggers option has been implemented for pt-online-schema-change in case users want to rename the tables manually, when the load is low.
+
+New --new-table-name option has been added to pt-online-schema-change which can be used to specify the temporary table name.
+
+* Fixed bug #1199589: pt-archiver would delete the data even with the --dry-run option.
+
+* Fixed bug #821692: pt-query-digest didn't distill LOAD DATA correctly.
+
+* Fixed bug #984053: pt-query-digest didn't distill INSERT/REPLACE without INTO correctly.
+
+* Fixed bug #1206677: pt-agent docs were referencing wrong web address.
+
+* Fixed bug #1210537: pt-table-checksum --recursion-method=cluster would crash if no nodes were found.
+
+Percona Toolkit packages can be downloaded from
+http://www.percona.com/downloads/percona-toolkit/ or the Percona Software
+Repositories (http://www.percona.com/software/repositories
+
+Changelog
+---------
+
+* Added Query_time histogram bucket counts to pt-query-digest JSON output
+* Added pt-online-schema-change --[no]drop-triggers option
+* Fixed bug #1199589: pt-archiver deletes data despite --dry-run
+* Fixed bug #944051: pt-table-checksum has ambiguous exit status
+* Fixed bug #1209436: pt-kill --log-dsn may not work on Perl 5.8
+* Fixed bug #1210537: pt-table-checksum --recursion-method=cluster crashes if no nodes are found
+* Fixed bug #1215608: pt-online-schema-change new table suffix is hard-coded
+* Fixed bug #1229861: pt-table-sync quotes float values, can't sync
+* Fixed bug #821692: pt-query-digest doesn't distill LOAD DATA correctly
+* Fixed bug #984053: pt-query-digest doesn't distill INSERT/REPLACE without INTO correctly
+* Fixed bug #1206728: pt-deadlock-logger 2.2 requires DSN on command line
+* Fixed bug #1226721: pt-agent on CentOS 5 fails to send data
+* Fixed bug #821690: pt-query-digest doesn't distill IF EXISTS correctly
+* Fixed bug #1206677: pt-agent docs reference clodu.percona.com
+
+v2.2.4 released 2013-07-18
+==========================
+
+Percona Toolkit 2.2.4 has been released. This release two new features and a number of bugfixes. 
+
+pt-query-digest --output json includes query examples as of v2.2.3. Some people might not want this because it exposes real data. New option, --output json-anon, has been implemented. This option will provide the same data without query examples. It's "anonymous" in the sense that there's no identifying data; nothing more than schema and table structs can be inferred from fingerprints. 
+
+When using drop swap with pt-online-schema-change there is some production impact. This impact can be measured because tool outputs the current timestamp on lines for operations that may take awhile.
+
+* Fixed bug #1163735: pt-table-checksum fails if explicit_defaults_for_timestamp is enabled in 5.6
+pt-table-checksum would fail if variable explicit_defaults_for_timestamp was enabled in MySQL 5.6.
+
+* Fixed bug #1182856: Zero values causes "Invalid --set-vars value: var=0"
+Trying to assign 0 to any variable by using --set-vars option would cause “Invalid --set-vars value” message. 
+
+* Fixed bug #1188264: pt-online-schema-change error copying rows: Undefined subroutine &pt_online_schema_change::get
+Fixed the typo in the pt-online-schema-change code that could lead to a tool crash when copying the rows.
+
+* Fixed bug #1199591: pt-table-checksum doesn't use non-unique index with highest cardinality
+pt-table-checksum was using the first non-unique index instead of the one with the highest cardinality due to a sorting bug.
+
+Percona Toolkit packages can be downloaded from
+http://www.percona.com/downloads/percona-toolkit/ or the Percona Software
+Repositories (http://www.percona.com/software/repositories
+
+Changelog
+---------
+
+* Added pt-query-digest anonymous JSON output
+* Added pt-online-schema-change timestamp output
+* Fixed bug #1136559: pt-table-checksum: Deep recursion on subroutine "SchemaIterator::_iterate_dbh"
+* Fixed bug #1163735: pt-table-checksum fails if explicit_defaults_for_timestamp is enabled in 5.6
+* Fixed bug #1182856: Zero values causes "Invalid --set-vars value: var=0"
+* Fixed bug #1188264: pt-online-schema-change error copying rows: Undefined subroutine &pt_online_schema_change::get
+* Fixed bug #1195034: pt-deadlock-logger error: Use of uninitialized value $ts in pattern match (m//)
+* Fixed bug #1199591: pt-table-checksum doesn't use non-unique index with highest cardinality
+* Fixed bug #1168434: pt-upgrade reports differences on NULL
+* Fixed bug #1172317: pt-sift does not work if pt-stalk did not collect due to a full disk
+* Fixed bug #1176010: pt-query-digest doesn't group db and `db` together
+* Fixed bug #1137556: pt-heartbeat docs don't account for --utc
+* Fixed bug #1168106: pt-variable-advisor has the wrong default value for innodb_max_dirty_pages_pct in 5.5 and 5.6
+* Fixed bug #1168110: pt-variable-advisor shows key_buffer_size in 5.6 as unconfigured (even though it is)
+* Fixed bug #1171968: pt-query-digest docs don't mention --type=rawlog
+* Fixed bug #1174956: pt-query-digest and pt-fingerprint don't strip some multi-line comments
+
+
+v2.2.3 released 2013-06-17
+==========================
+
+Percona Toolkit 2.2.3 has been released which has only two changes: pt-agent
+and a bug fix for pt-online-schema-change.  pt-agent is not a command line
+tool but a client-side agent for Percona Cloud Tools.  Visit
+https://cloud.percona.com for more information.  The pt-online-schema-change
+bug fix is bug 1188002: pt-online-schema-change causes "ERROR 1146 (42S02):
+"Table 'db._t_new' doesn't exist".  This happens when the tool's triggers
+cannot be dropped.
+
+Percona Toolkit packages can be downloaded from
+http://www.percona.com/downloads/percona-toolkit/ or the Percona Software
+Repositories (http://www.percona.com/software/repositories/).
+
+Changelog
+---------
+
+* Added new tool: pt-agent
+* Fixed bug 1188002: pt-online-schema-change causes "ERROR 1146 (42S02): Table 'db._t_new' doesn't exist"
+
+v2.2.2 released 2013-04-24
+==========================
+
+Percona Toolkit 2.2.2 has been released.  This is the second release of
+the 2.2 series and aims to fix bugs in the previous release and provide
+usability enhacements to the toolkit.
+
+Users may note the revival of the --show-all option in pt-query-digest.
+This had been removed in 2.2.1, but resulted in too much output in
+certain cases.
+
+A new --recursion-method was added to pt-table-checksum: cluster.  This
+method attempts to auto-discover cluster nodes, alleviating the need to
+specify cluster node DSNs in a DSN table (--recursion-method=dsn).
+
+The following highlights some of the more interesting and "hot" bugs in
+this release:
+
+* Bug #1127450: pt-archiver --bulk-insert may corrupt data
+
+pt-archiver --bulk-insert didn't work with --charset UTF-8. This revealed
+a case where the tool could corrupt data by double-encoding.  This is now
+fixed, but remains relatively dangerous if using DBD::mysql 3.0007 which
+does not handle UTF-8 properly.
+
+* Bug #1163372: pt-heartbeat --utc --check always returns 0
+
+Unfortunately, the relatively new --utc option for pt-heart was still
+broken because "[MySQL] interprets date as a value in the current time zone
+and converts it to an internal value in UTC."  Now the tool works correctly
+with --utc by specifying "SET time_zone='+0:00'", and older versions of
+the tool can be made to work by specifying --set-vars "time_zone='+0:00'".
+
+* Bug #821502: Some tools don't have --help or --version
+
+pt-align, pt-mext, pt-pmp and pt-sift now have both options.
+
+This is another solid bug fix release, and all users are encouraged to upgrade.
+
+Percona Toolkit packages can be downloaded from
+http://www.percona.com/downloads/percona-toolkit/ or the Percona Software
+Repositories (http://www.percona.com/software/repositories/).
+
+Changelog
+---------
+
+* Added --show-all to pt-query-digest
+* Added --recursion-method=cluster to pt-table-checksum
+* Fixed bug 1127450: pt-archiver --bulk-insert may corrupt data
+* Fixed bug 1163372: pt-heartbeat --utc --check always returns 0
+* Fixed bug 1156901: pt-query-digest --processlist reports duplicate queries for replication thread
+* Fixed bug 1160338: pt-query-digest 2.2 prints unwanted debug info on tcpdump parsing errors
+* Fixed bug 1160918: pt-query-digest 2.2 prints too many string values
+* Fixed bug 1156867: pt-stalk prints the wrong variable name in verbose mode when --function is used
+* Fixed bug 1081733: pt-stalk plugins can't access the real --prefix
+* Fixed bug 1099845: pt-table-checksum pxc same_node function incorrectly uses wsrep_sst_receive_address
+* Fixed bug  821502: Some tools don't have --help or --version
+* Fixed bug  947893: Some tools use @@hostname without /*!50038*/
+* Fixed bug 1082406: An explicitly set wsrep_node_incoming_address may make SHOW STATUS LIKE 'wsrep_incoming_addresses' return a portless address
+
+v2.2.1 released 2013-03-14
+==========================
+
+Percona Toolkit 2.2.1 has been released.  This is the first release in
+the new 2.2 series which supersedes the 2.1 series and renders the 2.0
+series obsolete.  We plan to do one more bug fix release for 2.1 (2.1.10),
+but otherwise all new development and fixes and will now focus on 2.2.
+
+Percona Toolkit 2.2 has been several months in the making, and it turned
+out very well, with many more new features, changes, and improvements than
+originally anticipated.  Here are the highlights:
+
+----
+
+* Official support for MySQL 5.6
+
+We started beta support for MySQL 5.6 in 2.1.8 when 5.6 was still beta.
+Now that 5.6 is GA, so is our support for it.  Check out the Percona Toolkit
+supported platforms and versions:
+http://www.percona.com/mysql-support/policies/percona-toolkit-supported-platforms-and-versions
+
+When you upgrade to MySQL 5.6, be sure to upgrade to Percona Toolkit 2.2, too.
+
+* Official support for Percona XtraDB Cluster (PXC)
+
+We also started beta support for Percona XtraDB Cluster in 2.1.8, but
+now that support is official in 2.2 because we have had many months to
+work with PXC and figure out which tools work with it and how.  There's
+still one noticeable omission: pt-table-sync.  It's still unclear if
+or how one would sync a cluster that, in theory, doesn't become out-of-sync.
+As Percona XtraDB Cluster develops, Percona Toolkit will continue to
+evolve to support it.
+
+* pt-online-schema-change (pt-osc) is much more resilient
+
+pt-online-schema-change 2.1 has been a great success, and people have been
+using it for evermore difficult and challenging tasks.  Consequently, we
+needed to make it "try harder", even though it already tried pretty hard
+to keep working despite recoverable errors and such.  Whereas pt-osc 2.1
+only retries certain operations, pt-osc 2.2 retries every critical operation,
+and its tries and wait time between tries for all operations are configurable.
+Also, we removed --lock-wait-timeout which set innodb_lock_wait_timeout
+because that now conflicts, or is at least confused with, lock_wait_timeout
+(introduced in MySQL 5.5) for metadata locks.  Now --set-vars is used to
+set both of these (or any) system variables.  For a quick intro to metadata
+locks and how they may affect you, see Ovais's article:
+http://www.mysqlperformanceblog.com/2013/02/01/implications-of-metadata-locking-changes-in-mysql-5-5/
+
+What does this all mean?  In short: pt-online-schema-change 2.2 is far more
+resilient out of the box.  It's also aware of metadata locks now, whereas
+2.1 was not really aware of them.  And it's highly configurable, so you can
+make the tool try _very_ hard to keep working.
+
+* pt-upgrade is brand-new
+
+pt-upgrade was written once long ago, thrown into the world, and then never
+heard from again... until now.  Now that we have four base versions of
+MySQL (5.0, 5.1, 5.5, and 5.6), plus at least four major forks (Percona
+Server, MariaDB, Percona XtraDB Cluster, and MariaDB Galera Cluster),
+upgrades are fashionable, so to speak.  Problem is: "original" pt-upgrade
+was too noisy and too complex.  pt-upgrade 2.2 is far simpler and far
+easier to use.  It's basically what you expect from such a tool.
+
+Moreover, it has a really helpful new feature: "reference results", i.e.
+saved results from running queries on a server.  Granted, this can take
+_a lot_ of disk space, but it allows you to "run now, compare later."
+
+If you're thinking about upgrading, give pt-upgrade a try.  It also reads
+every type of log now (slow, general, binary, and tcpdump), so you shouldn't
+have a problem finding queries to run and compare.
+
+* pt-query-digest is simpler
+
+pt-query-digest 2.2 has fewer options now.  Basically, we re-focused it
+on its primary objective: analyzing MySQL query logs.  So the ability
+to parse memcached, Postgres, Apache, and other logs was removed.  We
+also removed several options that probably nobody ever used, and
+changed/renamed other options to be more logical.  The result is a simpler,
+more focused tool, i.e. less overwhelming.
+
+Also, pt-query-digest 2.2 can save results in JSON format (--output=json).
+This feature is still in development while we determine the optimal
+JSON structure.
+
+* Version check is on by default
+
+Way back in 2.1.4, released September/October 2012, we introduced a feature
+called "version check" into most tools: http://percona.com/version-check
+It's like a lot of software that automatically checks for updates, but
+it's also more: it's a free service from Percona that advises when certain
+programs (Percona Toolkit tools, MySQL, Perl, etc.) are either out of date
+or are known bad versions.  For example, there are two versions of the
+DBD::mysql Perl module that have problems.  And there are certain versions
+of MySQL that have critical bugs.  Version check will warn you about these
+if your system is running them.
+
+What's new in 2.2 is that, whereas this feature (specifically, the option
+in tools: --version-check) was off by default, now it's on by default.
+If the IO::Socket::SSL Perl module is installed (easily available through
+your package manager), it will use a secure (https) connection over the web,
+else it will use a standard (http) connection.
+
+Check out http://percona.com/version-check for more information.
+
+* pt-query-advisor, pt-tcp-model, pt-trend, and pt-log-player are gone
+
+We removed pt-query-advisor, pt-tcp-model, pt-trend, and pt-log-player.
+Granted, no tool is ever really gone: if you need one of these tools,
+get it from 2.1.  pt-log-player is now superseded by Percona Playback
+(http://www.percona.com/doc/percona-playback/).  pt-query-advisor was
+removed so that we can focus our efforts on its online counterpart instead:
+https://tools.percona.com/query-advisor.  The other tools were special
+projects that were not widely used.
+
+* pt-stalk and pt-mysql-summary have built-in MySQL options
+
+No more "pt-stalk -- -h db1 -u me".  pt-stalk 2.2 and pt-mysql-summary 2.2
+have all the standard MySQL options built-in, like other tools: --user,
+--host, --port, --password, --socket, --defaults-file.  So now the command
+line is what you expect: pt-stalk -h dhb1 -u me.
+
+* pt-stalk --no-stalk is no longer magical
+
+Originally, pt-stalk --no-stalk was meant to simulate pt-collect, i.e.
+collect once and exit.  To do that, the tool magically set some options
+and clobbered others, resulting in no way to do repeated collections
+at intervals.  Now --no-stalk means only that: don't stalk, just collect,
+respecting --interval and --iterations as usual.  So to collect once
+and exit: pt-stalk --no-stalk --iterations 1.
+
+* pt-fk-error-logger and pt-deadlock-logger are standardized
+
+Similar to the pt-stalk --no-stalk changes, pt-fk-error-logger and
+pt-deadlock-logger received mini overhauls in 2.2 to make their
+run-related options (--run-time, --interval, --iterations) standard.
+If you hadn't noticed, one tool would run forever by default, while
+the other would run once and exit.  And each treated their run-related
+options a little differently.  This magic is gone now: both tools run
+forever by default, so specify --iterations or --run-time to limit how
+long they run.
+
+----
+
+There were other miscellaneous bug fixes, too.  See
+https://launchpad.net/percona-toolkit/+milestone/2.2.1 for the full list.
+
+As the first release in a new series, 2.2 features are not yet finalized.
+In other words, we may change things like the pt-query-digest --output json
+format in future releases after receiving real-world feedback.
+
+Percona Toolkit 2.2 is an exciting release with many helpful new
+features.  Users are encouraged to begin upgrading, particularly given
+that, except for the forthcoming 2.1.10 release, no more work will be
+done on 2.1 (unless you're a Percona customer with a support contract or
+other agreement).
+
+If you upgrade from 2.1 to 2.2, be sure to re-read tools' documentation
+to see what has changed because much as changed for certain tools.

+
+v2.1.9 released 2013-02-14
+==========================
+
+Percona Toolkit 2.1.9 has been released.  This release primarily aims to
+restore backwards-compatibility with pt-heartbeat 2.1.7 and older, but it
+also has important bug fixes for other tools.
+
+* Fixed bug 1103221: pt-heartbeat 2.1.8 doesn't use precision/sub-second timestamps
+* Fixed bug 1099665: pt-heartbeat 2.1.8 reports big time drift with UTC_TIMESTAMP
+
+The previous release switched the time authority from Perl to MySQL, and from
+local time to UTC. Unfortunately, these changes caused a loss of precision and,
+if mixing versions of pt-heartbeat, made the tool report a huge amount of
+replication lag.  This release makes the tool compatible with pt-heartbeat
+2.1.7 and older again, but the UTC behavior introduced in 2.1.8 is now only
+available by specifying the new --utc option.
+
+* Fixed bug  918056: pt-table-sync false-positive error "Cannot nibble table because MySQL chose no index instead of the PRIMARY index"
+
+This is an important bug fix for pt-table-sync: certain chunks from
+pt-table-checksum resulted in an impossible WHERE, causing the false-positive
+"Cannot nibble" error, if those chunks had diffs.
+
+* Fixed bug 1099836: pt-online-schema-change fails with "Duplicate entry" on MariaDB
+
+MariaDB 5.5.28 (https://kb.askmonty.org/en/mariadb-5528-changelog/) fixed
+a bug: "Added warnings for duplicate key errors when using INSERT IGNORE".
+However, standard MySQL does not warn in this case, despite the docs saying
+that it should.  Since pt-online-schema-change has always intended to ignore
+duplicate entry errors by using "INSERT IGNORE", it now handles the MariaDB
+case by also ignoring duplicate entry errors in the code.
+
+* Fixed bug 1103672: pt-online-schema-change makes bad DELETE trigger if PK is re-created with new columns
+
+pt-online-schema-change 2.1.9 handles another case of changing the primary key.
+However, since changing the primary key is tricky, the tool stops if --alter
+contains "DROP PRIMARY KEY", and you have to specify --no-check-alter to
+acknowledge this case.
+
+* Fixed bug 1099933: pt-stalk is too verbose, fills up log
+
+Previously, pt-stalk printed a line for every check.  Since the tool is
+designed to be a long-running daemon, this could result in huge log files
+with "matched=no" lines. The tool has a new --verbose option which makes it
+quieter by default.
+
+All users should upgrade, but in particular, users of versions 2.1.7 and
+older are strongly recommended to skip 2.1.8 and go directly to 2.1.9.
+
+Users of pt-heartbeat in 2.1.8 who prefer the UTC behavior should keep in
+mind that they will have to use the --utc option after upgrading.

+
+v2.1.8 released 2012-12-21
+==========================
+
+Percona Toolkit 2.1.8 has been released.  This release includes 28 bug fixes, beta support for MySQL 5.6, and extensive support for Percona XtraDB Cluster (PXC).  Users intending on running the tools on Percona XtraDB Cluster or MySQL 5.6 should upgrade.  The following tools have been verified to work on PXC versions 5.5.28 and newer:
+
+* pt-table-chcecksum
+* pt-online-schema-change
+* pt-archive
+* pt-mysql-summary
+* pt-heartbeat
+* pt-variable-advisor
+* pt-config-diff
+* pt-deadlock-logger
+
+However, there are limitations when running these tools on PXC; see the Percona XtraDB Cluster section in each tool's documentation for further details.  All other tools, with the exception of pt-slave-find, pt-slave-delay and pt-slave-restart, should also work correctly, but in some cases they have not been modified to take advantage of PXC features, so they may behave differently in future releases.
+
+The bug fixes are widely assorted.  The following highlights some of the more interesting and "hot" bugs:
+
+* Fixed bug 1082599: pt-query-digest fails to parse timestamp with no query
+
+Slow logs which include timestamps but no query--which can happen if using slow_query_log_timestamp_always in Percona Server--were misparsed, resulting in an erroneous report.  Now such no-query events show up in reports as ``/* No query */``.
+
+* Fixed bug 1078838: pt-query-digest doesn't parse general log with "Connect user as user"
+
+The "as" was misparsed and the following word would end up reported as the database; pt-query-digest now handles this correctly.
+
+* Fixed bug 1015590: pt-mysql-summary doesn't handle renamed variables in Percona Server 5.5
+
+Some renamed variables had caused the Percona Server section to work unreliably.
+
+* Fixed bug 1074179:  pt-table-checksum doesn't ignore tables for --replicate-check-only
+
+When using --replicate-check-only, filter options like --databases and --tables were not applied.
+
+* Fixed bug 886059: pt-heartbeat handles timezones inconsistently
+
+Previously, pt-heartbeat respected the MySQL time zone, but this caused false readings (e.g. very high lag) with slaves running in different time zones.  Now pt-heartbeat uses UTC regardless of the server or MySQL time zone.
+
+* Fixed bug 1079341: pt-online-schema-change checks for foreign keys on MyISAM tables
+
+Since MyISAM tables can't have foreign keys, and the tool uses the information_schema to find child tables, this could cause unnecessary load on the server.
+
+2.1.8 continues the trend of solid bug fix releases, and all 2.1 users are encouraged to upgrade.

+v2.1.7 released 2012-11-19
+==========================
+
+Percona Toolkit 2.1.7 has been released which is a hotfix for two bugs when using pt-table-checksum with Percona XtraDB Cluster:
+
+* Bug 1080384: pt-table-checksum 2.1.6 crashes using PTDEBUG
+* Bug 1080385: pt-table-checksum 2.1.6 --check-binlog-format doesn't ignore PXC nodes
+
+If you're using pt-table-checksum with a Percona XtraDB Cluster, you should upgrade.  Otherwise, users can wait until the next full release.

+* Fixed bug 1080385: pt-table-checksum 2.1.6 --check-binlog-format doesn't ignore PXC nodes
+
+v2.1.6 released 2012-11-13
+==========================
+
+Percona Toolkit 2.1.6 has been released.  This release includes 33 bug fixes and three new features: pt-online-schema-change now handles renaming columns without losing data, removing one of the tool's limitations.  pt-online-schema-change also got two new options: --default-engine and --statistics.  Finally, pt-stalk now has a plugin hook interface, available through the --plugin option.  The bug fixes are widely assorted.  The following highlights some of the more interesting and "hot" bugs:
+
+* Bug 978133: pt-query-digest review table privilege checks don't work
+
+The same checks were removed from pt-table-checksum on 2.1.3 and pt-table-sync on 2.1.4, so this just follows suit.
+
+* Bug 938068: pt-table-checksum doesn't warn if binlog_format=row or mixed on slaves
+
+A particularly important fix, as it may stop pt-table-checksum from breaking replication in these setups.
+
+* Bug 1043438: pt-table-checksum doesn't honor --run-time while checking replication lag
+
+If you run multiple instances of pt-table-checksum on a badly lagged server, actually respecting --run-time stops the instances from divebombing the server when the replica catches up.
+
+* Bug 1062324: pt-online-schema-change DELETE trigger fails when altering primary key
+
+Fixed by choosing a key on the new table for the DELETE trigger.
+
+* Bug 1062563: pt-table-checksum 2.1.4 doesn't detect diffs on Percona XtraDB Cluster nodes
+
+A follow up to the same fix in the previous release, this adds to warnings for cases in which pt-table-checksum may work incorrectly and require some user intervention: One for the case of master -> cluster, and one for cluster1 -> cluster2.
+
+* Bug 821715: LOAD DATA LOCAL INFILE broken in some platforms
+
+This bug has hounded the toolkit for quite some time. In some platforms, trying to use LOAD DATA LOCAL INFILE would fail as if the user didn't have enough privileges to perform the operation.  This was a misdiagnoses from MySQL; The actual problem was that the libmysqlclient.so provided by some vendors was compiled in a way that disallowed users from using the statement without some extra work.  This fix adds an 'L' option to the DSNs the toolkit uses, tells the the tools to explicitly enables LOAD DATA LOCAL INFILE.  This affected two pt-archiver and pt-upgrade, so if you are on an effected OS and need to use those, you can simply tag an L=1 to your DSN and everything should start working.
+
+* Bug 866075: pt-show-grant doesn't support column-level grants
+
+This was actually the 'hottest' bug in the tracker.
+
+This is another solid bug fix release, and all 2.1 users are encouraged to upgrade.

+
+v2.1.5 released 2012-10-08
+==========================
+
+Percona Toolkit 2.1.5 has been released.  This release is less than two weeks after the release of 2.1.4 because we wanted to address these bugs quickly:
+
+* Bug 1062563: pt-table-checksum 2.1.4 doesn't detect diffs on Percona XtraDB Cluster nodes
+
+* Bug 1063912: pt-table-checksum 2.1.4 miscategorizes Percona XtraDB Cluster-based slaves as cluster nodes
+
+* Bug 1064016: pt-table-sync 2.1.4 --version-check may not work with HTTPS/SSL
+
+The first two bugs fix how pt-table-checksum works with Percona XtraDB Cluster (PXC).  Although the 2.1.4 release did introduce support for PXC, these bugs prevented pt-table-checksum from working correctly with a cluster.
+
+The third bug is also related to a feature new in 2.1.4: --version-check.  The feature uses HTTPS/SSL by default, but some modules in pt-table-sync weren't update which could prevent it from working on older systems.  Related, the version check web page mentioned in tools' documentation was also created.
+
+If you're using pt-table-checksum with a Percona XtraDB Cluster, you should definitely upgrade.  Otherwise, users can wait until 2.1.6 for another full release.

+Percona Toolkit packages can be downloaded from http://www.percona.com/downloads/percona-toolkit/ or the Percona Software Repositories (http://www.percona.com/software/repositories/).

+==========================
+
+Percona Toolkit 2.1.4 has been released.  This release includes 26 bug fixes and three new features: Making pt-table-checksum work with Percona XtraDB Cluster, adding a --run-time option to pt-table-checksum, and implementing the "Version Check" feature, enabled through the --version-check switch.  For further information on --version-check, see http://www.mysqlperformanceblog.com/2012/09/10/introducing-the-version-check-feature-in-percona-toolkit/.  The bug fixes are widely assorted.

+* Fixed bug 1017626: pt-table-checksum doesn't work with Percona XtraDB Cluster
+
+Note that this requires Percona XtraDB Cluster 5.5.27-23.6 or newer, as the fix depends on this bug https://bugs.launchpad.net/codership-mysql/+bug/1023911 being resolved.
+
+* Fixed bug 1034170: pt-table-checksum --defaults-file isn't used for slaves
+
+Previously, users had no recourse but using --recursion-method in conjunction with a dsn table to sidestep this bug, so this fix is a huge usability gain.  This was caused by the toolkit not copying the -F portion of the main dsn.
+
+* Fixed bug 1039184: pt-upgrade error "I need a right_sth argument"
+
+Which were stopping pt-upgrade from working on a MySQL 4.1 host.
+
+* Fixed bug 1036747: pt-table-sync priv checks need to be removed
+
+The same checks were removed in the previous release from pt-table-checksum, so this continues the trend.
+
+* Fixed bug 1038995: pt-stalk --notify-by-email fails
+
+This was a bug in our shell option parsing library, and would potentially affect any option starting with 'no'.
+
+Like 2.1.3, this is another solid bug fix release, and 2.1 users are encouraged to upgrade.

+v2.1.3 released 2012-08-03
+==========================
+
+Percona Toolkit 2.1.3 has been released.  This release includes 31 bug fixes and one new feature: pt-kill --log-dsn to log information about killed queries to a table.  The bug fixes are widely assorted.  The following highlights some of the more interesting and "hot" bugs:
+
+* Fixed bug 916168: pt-table-checksum privilege check fails on MySQL 5.5
+
+pt-table-checksum used to check the user's privileges, but the method was not always reliable, and due to http://bugs.mysql.com/bug.php?id=61846 it became quite unreliable on MySQL 5.5.  So the privs check was removed altogether, meaning that the tool may fail later if the user's privileges are insufficient.
+
+* Fixed bug 950294: pt-table-checksum should always create schema and tables with IF NOT EXISTS
+
+In certain cases where the master and replicas have different schemas and/or tables, pt-table-checksum could break replication because the checksums table did not exist on a replica.
+
+* Fixed bug 821703: pt-query-digest --processlist may crash
+* Fixed bug 883098: pt-query-digest crashes if processlist has extra columns
+
+Certain distributions of MySQL add extra columns to SHOW PROCESSLIST which caused pt-query-digest --processlist to crash at times.
+
+* Fixed bug 941469: pt-kill doesn't reconnect if its connection is lost
+
+pt-kill is meant to be a long-running daemon, so naturally it's important that it stays connected to MySQL.
+
+* Fixed bug 1004567: pt-heartbeat --update --replace causes duplicate key error
+
+The combination of these pt-heartbeat options could cause replication to break due to a duplicate key error.
+
+* Fixed bug 1022628: pt-online-schema-change error: Use of uninitialized value in numeric lt (<) at line 6519
+
+This bug was related to how --quiet was handled, and it could happen even if --quiet wasn't given on the command line.
+
+All in all, this is solid bug fix release, and 2.1 users are encouraged to upgrade.

+
+v2.1.2 released 2012-06-12
+==========================
+
+Percona Toolkit 2.1.2 has been released.  This is a very important release because it fixes a critical bug in pt-table-sync (bug 1003014) which caused various failures.  All users of Percona Toolkit 2.1 should upgrade to this release.  There were 47 other bug fixes, several new options, and other changes.  The following is a high-level summary of the most important changes.
+
+In addition to the critical bug fix mentioned above, another important pt-table-sync bug was fixed, bug 1002365: --ignore-* options did not work with --replicate.  The --lock-and-rename feature of the tool was also disabled unless running MySQL 5.5 or newer because it did not work reliably in earlier versions of MySQL.
+
+Several important pt-table-checksum bugs were fixed.  First, a bug caused the tool to ignore the primary key.  Second, the tool did not wait for the checksum table to replicate, so it could select from a nonexistent table on a replica and crash.  Third, it did not check if all checksum queries were safe and chunk index with more than 3 columns could cause MySQL to scan many more rows than expected.
+
+pt-online-schema-change received many improvements and fixes: it did not retry deadlocks, but now it does; --no-swap-tables caused an error; it did not handle column renames; it did not allow disabling foreign key checks; --dry-run always failed on tables with foreign keys; it used different keys for chunking and triggers; etc.  In short: pt-online-schema-change 2.1.2 is superior to 2.1.1.
+
+Two pt-archiver bugs were fixed: bug 979092, --sleep conflicts with bulk operations; and bug 903379, --file doesn't create a file.
+
+--recursion-method=none was implemented in pt-heartbeat, pt-online-schema-change, pt-slave-find, pt-slave-restart, pt-table-checksum, and pt-table-sync.  This allows these tools to avoid executing SHOW SLAVE STATUS which requires a privilege not available to Amazon RDS users.
+
+Other bugs were fixed in pt-stalk, pt-variable-advisor, pt-duplicate-key-checker, pt-diskstats, pt-query-digest, pt-sift, pt-kill, pt-summary, and pt-deadlock-logger.
+
+Percona Toolkit 2.1.2 should be backwards-compatible with 2.1.1, so users are strongly encouraged to upgrade.
+
+Percona Toolkit packages can be downloaded from http://www.percona.com/downloads/percona-toolkit/ or the Percona Software Repositories (http://www.percona.com/software/repositories/).

+
+v2.1.1 released 2012-04-03
+==========================
+
+Percona Toolkit 2.1.1 has been released.  This is the first release in the
+new 2.1 series which supersedes the 2.0 series.  We will continue to fix bugs
+in 2.0, but 2.1 is now the focus of development.
+
+2.1 introduces a lot of new code for:
+
+* pt-online-schema-change (completely redesigned)
+* pt-mysql-summary (completely redesigned)
+* pt-summary (completely redesigned)
+* pt-fingerprint (new tool)
+* pt-table-usage (new tool)
+
+There were also several bug fixes.
+
+The redesigned tools are meant to replace their 2.0 counterparts because
+the 2.1 versions have the same or more functionality and they are simpler
+and more reliable.  pt-online-schema-change was particularly enhanced to
+be as safe as possible given that the tool is inherently risky.
+
+Percona Toolkit packages can be downloaded from
+http://www.percona.com/downloads/percona-toolkit/ or the Percona Software
+Repositories (http://www.percona.com/software/repositories/).
+
+Changelog
+---------
+
+* Completely redesigned pt-online-schema-change
+* Completely redesigned pt-mysql-summary
+* Completely redesigned pt-summary
+* Added new tool: pt-table-usage
+* Added new tool: pt-fingerprint
+* Fixed bug 955860: pt-stalk doesn't run vmstat, iostat, and mpstat for --run-time
+* Fixed bug 960513: SHOW TABLE STATUS is used needlessly
+* Fixed bug 969726: pt-online-schema-change loses foreign keys
+* Fixed bug 846028: pt-online-schema-change does not show progress until completed
+* Fixed bug 898695: pt-online-schema-change add useless ORDER BY
+* Fixed bug 952727: pt-diskstats shows incorrect wr_mb_s
+* Fixed bug 963225: pt-query-digest fails to set history columns for disk tmp tables and disk filesort

+* Fixed bug 953461: pt-upgrade manual broken 'output' section
+* Fixed bug 949653: pt-table-checksum docs don't mention risks posed by inconsistent schemas
+
+v2.0.4 released 2012-03-07
+==========================
+
+Percona Toolkit 2.0.4 has been released.  23 bugs were fixed in this release,
+and three new features were implemented.  First, --filter was added to pt-kill
+which allows for arbitrary --group-by.  Second, pt-online-schema-change now
+requires that its new --execute option be given, else the tool will just check
+the tables and exit.  This is a safeguard to encourage users to read the
+documentation, particularly when replication is involved.  Third, pt-stalk
+also received a new option: --[no]stalk.  To collect immediately without
+stalking, specify --no-stalk and the tool will collect once and exit.
+
+This release is completely backwards compatible with previous 2.0 releases.
+Given the number of bug fixes, it's worth upgrading to 2.0.4.
+
+Changelog
+---------
+
+* Added --filter to pt-kill to allow arbitrary --group-by
+* Added --[no]stalk to pt-stalk (bug 932331)
+* Added --execute to pt-online-schema-change (bug 933232)

+* Fixed bug 940503: pt-stalk disk space checks wrong on 32bit platforms
+* Fixed bug 944420: --daemonize doesn't always close STDIN
+* Fixed bug 945834: pt-sift invokes pt-diskstats with deprecated argument
+* Fixed bug 945836: pt-sift prints awk error if there are no stack traces to aggregate
+* Fixed bug 945842: pt-sift generates wrong state sum during processlist analysis

+* Fixed bug 946776: pt-table-checksum ignores --lock-wait-timeout
+* Fixed bug 940440: Bad grammar in pt-kill docs
+
+v2.0.3 released 2012-02-03
+==========================
+
+Percona Toolkit 2.0.3 has been released.  The development team was very
+busy last month making this release significant: two completely
+redesigned and improved tools, pt-diskstats and pt-stalk, and 20 bug fixes.
+
+Both pt-diskstats and pt-stalk were redesigned and rewritten from the ground
+up.  This allowed us to greatly improve these tools' functionality and
+increase testing for them.  The accuracy and output of pt-diskstats was
+enhanced, and the tool was rewritten in Perl.  pt-collect was removed and
+its functionality was put into a new, enhanced pt-stalk.  pt-stalk is now
+designed to be a stable, long-running daemon on a variety of common platforms.
+It is worth re-reading the documentation for each of these tools.
+
+The 20 bug fixes cover a wide range of problems.  The most important are
+fixes to pt-table-checksum, pt-iostats, and pt-kill.  Apart from pt-diskstats,
+pt-stalk, and pt-collect (which was removed), no other tools were changed
+in backwards-incompatible ways, so it is worth reviewing the full changelog
+for this release and upgrading if you use any tools which had bug fixes.
+
+Thank you to the many people who reported bugs and submitted patches.

+
+v2.0.1 released 2011-12-30
+==========================
+
+The Percona Toolkit development team is proud to announce a new major version:
+2.0.  Beginning with Percona Toolkit 2.0, we are overhauling, redesigning, and
+improving the major tools.  2.0 tools are therefore not backwards compatible
+with 1.0 tools, which we still support but will not continue to develop.
+
+New in Percona Toolkit 2.0.1 is a completely redesigned pt-table-checksum.
+The original pt-table-checksum 1.0 was rather complex, but it worked well
+for many years.  By contrast, the new pt-table-checksum 2.0 is much simpler but
+also much more efficient and reliable.  We spent months rethinking, redesigning,
+and testing every aspect of the tool.  The three most significant changes:
+pt-table-checksum 2.0 does only --replicate, it has only one chunking algorithm,
+and its memory usage is stable even with hundreds of thousands of tables and
+trillions of rows.  The tool is now dedicated to verifying MySQL replication
+integrity, nothing else, which it does extremely well.
+
+In Percona Toolkit 2.0.1 we also fixed various small bugs and forked ioprofile
+and align (as pt-ioprofile and pt-align) from Aspersa.
+
+If you still need functionalities in the original pt-table-checksum,
+the latest Percona Toolkit 1.0 release remains available for download.
+Otherwise, all new development in Percona Toolkit will happen in 2.0.

+v1.0.1 released 2011-09-01
+==========================
+
+Percona Toolkit 1.0.1 has been released.  In July, Baron announced planned
+changes to Maatkit and Aspersa development;[1]  Percona Toolkit is the
+result.  In brief, Percona Toolkit is the combined fork of Maatkit and
+Aspersa, so although the toolkit is new, the programs are not.  That means
+Percona Toolkit 1.0.1 is mature, stable, and production-ready.  In fact,
+it's even a little more stable because we fixed a few bugs in this release.
+
+Percona Toolkit packages can be downloaded from
+http://www.percona.com/downloads/percona-toolkit/
+or the Percona Software Repositories
+(http://www.percona.com/docs/wiki/repositories:start).
+
+Although Maatkit and Aspersa development use Google Code, Percona Toolkit
+uses Launchpad: https://launchpad.net/percona-toolkit

+v0.9.5 released 2011-08-04
+==========================
+
+Percona Toolkit 0.9.5 represents the completed transition from Maatkit and Aspersa.  There are no bug fixes or new features, but some features have been removed (like --save-results from pt-query-digest).  This release is the starting point for the 1.0 series where new development will happen, and no more changes will be made to the 0.9 series.
