Setting the target of a bugfix

When new bugs are entered, we try to give them a target in which version the bug will be fixed. If a bug is set to post 1.2, that means the developers think this bug is not important enough to block a 1.0.x release. Of course you can make sure these post 1.2 issues are fixed in the 1.0.x release by providing patches for these issues.

Some criteria are:

  • Only gtk2, qt and win32 widget sets are stable in 1.0.x. Bugs for other widget set (carbon) are set to post 1.2.
  • Until 1.0 there will be a feature freeze. New features and components generally get a post 1.2 target. Bugs affecting stability have a higher priority than bugs fixing the implementation of a property.
  • Some components are not stable enough and should be disabled for 1.0.x. If they are disabled, then fixing them before 1.2 will not be necessary.

Lazarus branches / version numbers

This ASCII art schema shows what the Lazarus developers have chosen as branching policy for the Lazarus 1.0 release. It also illustrates the way current development works. Time goes from left to right; the different branches are shown vertically. B indicates a branch point, T a tag (release).
