If you want to help, a nice first step to get familiar with improving the system is to review Pull Requests. For example, there are always very simple ones (like the ones listed here in "Cleanup Unused Variables”) that are fairly easy to understand and review. Open Pull requests are here: https://github.com/pharo-project/pharo/pulls Debugger improvements and Fixes =========================== - Added empty selection interval to force SpCodePresenter to auto-scroll. #8428 https://github.com/pharo-project/pharo/pull/8428 - OCDoitTest-testDoItContextReadIvar #8437 https://github.com/pharo-project/pharo/pull/8437 - 7763-Does-BlockClosurecull-need-the-pragma-debuggerCompleteToSender #8427 https://github.com/pharo-project/pharo/pull/8427 - Inspecting a Text no longer shows the formatted text #8352 https://github.com/pharo-project/pharo/issues/8352 Refactoring Improvements ======================== - Fix broken tests - extract method and ocurrences #8420 https://github.com/pharo-project/pharo/pull/8420 - RB - Add message to kwon how many occurrences were replaced #8380 https://github.com/pharo-project/pharo/pull/8380 Fixes ===== - 8168-CompiledMethodreferencedClasses-should-not-take-class-variables-into-account #8240 https://github.com/pharo-project/pharo/pull/8240 - Mouse events were sent twice when using an event handler #8404 https://github.com/pharo-project/pharo/pull/8404 - Mouse over event is sent multiple times #8401 https://github.com/pharo-project/pharo/pull/8401 - Improve the Help for Spec2 #8410 https://github.com/pharo-project/pharo/pull/8410 - Fix a regression from earlier pharo that used to perserve order in sequences #8402 https://github.com/pharo-project/pharo/pull/8402 Cleanup Unused Variables ========================= - spec1-clean-ivars #8431 https://github.com/pharo-project/pharo/pull/8431 - remove two unused ivars in GT-Tests #8432 https://github.com/pharo-project/pharo/pull/8432 - Remove-unused-vars-RB #8422 https://github.com/pharo-project/pharo/pull/8422 -RBExtractMethodAndOccurrences-unused-ivar #8425 https://github.com/pharo-project/pharo/pull/8425 - 8354-SycRemoveMessageArgumentCommand-with-unused-ivar #8419 https://github.com/pharo-project/pharo/pull/8419
