ubuntu-dev-tools (0.31) UNRELEASED; urgency=low
[ Siegfried-Angel Gevatter Pujals (RainCT) ]
* pbuilder-dist:
* pbuilder-dist.new:
- Rewrite the script in Python to make it more robust and faster.
- ^^^ NOT FINISHED YET, DO NOT UPLOAD THIS! ^^^
* what-patch:
- If cdbs-edit-patch is used, output "cdbs (patchsys.mk)" instead of
just "cdbs" (LP: #195795).
@ -38,8 +37,11 @@ ubuntu-dev-tools (0.31) UNRELEASED; urgency=low
* mk-sbuild-lv
- don't install recommended packages during chroot install.
- allow customization of schroot.conf suffix and LV/snapshot sizes.
* what-patch:
- restore previous output behavior, added logic to verbose test instead.
- added details for each patch system report.
