22. By Colin Watson on 2009-03-19

No-change rebuild to fix lpia shared library dependencies.

21. By Steve Langasek on 2009-03-14

* debian/patches-ft2demos/compiler-hardening-fixes.patch: always check the
  return value of fread(), to appease hardened compilers such as what's
  used in Ubuntu by default. Set a good example, even if these demos
  shouldn't be security-sensitive! Also, along the way catch and fix a
  small memory leak on error. :)
* debian/patches-freetype/proper-armel-asm-declaration.patch: use __asm__
  for declaring assembly instead of asm, fixing a build failure on armel.

20. By Steve Langasek on 2009-03-13

* Drop spurious Suggests: on libfreetype6-dev. Closes: #363937.
* debian/patches-freetype/enable-subpixel-rendering.patch: enable subpixel
  rendering features, used by libcairo and xft to provide LCD colour
  filtering. This is considered no more or less evil than the bytecode
  interpreter which we also enable.
* Move debian/libfreetype6.copyright to debian/copyright, and selectively
  install it to the single binary package in debian/rules; the same
  copyright file is used for all the binaries anyway via symlinks, so
  there's no reason it shouldn't ship as debian/copyright.
  Closes: #381228.
* Clip redundant LICENSE.TXT and GPL.TXT files from the
  libfreetype6-dev package. Closes: #459802.

* Merge from Debian unstable, remaining changes:
  - debian/patches-freetype/enable-subpixel-rendering.patch:
    + enable subpixel rendering features, used by libcairo and xft to
      provide LCD colour filtering. This is considered no more or less
      evil than the bytecode interpreter which we also enable.

* Merge from debian testing (LP: #251369) , remaining changes:
  - debian/patches-freetype/enable-subpixel-rendering.patch:
    + enable subpixel rendering features, used by libcairo and xft to
      provide LCD colour filtering. This is considered no more or less
      evil than the bytecode interpreter which we also enable.
  - Work around Soyuz breakage.

* Modify Maintainer value to match the DebianMaintainerField
  specification.

16. By Scott James Remnant (Canonical) on 2007-09-20

* debian/patches-freetype/enable-subpixel-rendering.patch:
  - Restore patch that enables subpixel rendering features, now that
    libcairo and xft provide the ability for the specific lcd filter
    to be changed.
