This is really good stuff - we don't say thank you to everyone enough. Its easy to add new cool stuff... to safely fix ongoing history, and learn from old mistakes to create better tested solutions is really hard - and a testament to the durability and hard work of this community. Wow.

This week (10/2022) on the Pharo Issue Tracker

by Marcus Denker

We merged 3 PRs and fixed 4 Issue tracker entries. Especially #10972 is important: with this the bug that lead to an overly huge image size is fixed. Now one can actually see that Pharo10 is smaller than Pharo9 due to: - code cleanup: removal of dead code, simplifications, cleanups - sharing of literals across all methods as part of the image build - first small improvement of size of the data structures of the code (related to Protocol) (much more possible here, but it has to wait for Pharo11) There are more PRs ready for Pharo10 that just need a review to be merged: https://github.com/pharo-project/pharo/pulls Fixes ==== 10667-Installed-breakpoints-not-shown-in-UI-after-AST-cache-reset-during-image-saving #10962 https://github.com/pharo-project/pharo/pull/10962 ensure no literal is kept pinned in memory when building an image #10972 https://github.com/pharo-project/pharo/pull/10972 Extend class comment of Dictionary #10973 https://github.com/pharo-project/pharo/pull/10973
