Release preparation

  • Gather list of todos from developers
    • Martin: No blocking items.
    • Paul and Zeljan: clDefault, Carbon doesn't work correctly yet
    • Vincent: investigate what gdb version to distribute for win64
  • Add new LazTarget to the mantis for so we can postpone issue one release. Postponed issues can be set to 0.99, 1.0 or 1.2.

Bugs to be fixed

Things that need to be fixed before tagging:

Creating branch for release

  • Create fixes_0_9_30 branch (Vincent)
  • Set version number 0.9.31 in trunk (Vincent)
    • lazarus/ide/
    • lazarus/lcl/lclversion.pas
    • lazarus/lcl/lclbase.lpk
    • lazarus/packager/globallinks/lclbase*.lpl
    • lazarus/debian/changelog
    • lazarus/
    • open lazarus/lazarus.lpi in the IDE and change the version numbers in the project options dialog; this will change ide/lazarus.res too.

Create snapshots for new branch

These snapshots can be considered release candidates.

  • source (Vincent)
  • win32 (Vincent)
  • win64 (Vincent)
  • linux i386 rpm (Vincent)
  • linux x86_64 rpm (Vincent)
  • linux i386 deb (Vincent)
  • linux x86_64 deb (Vincent)
  • Mac OS X powerpc (Vincent)
  • Mac OS X i386 (Vincent)
  • Add deb snaphots to Ubuntu testing repo (Vincent)

Ask for testing

  • Informally announce (IRC, mailing list) a pending release (+/- week before actual release), so that people can test for regressions. (Vincent)
