- Report scope: Covers hrev58043 through hrev58187. After R1/beta5 release, back to "as usual" development with some report changes included.
- Packagefs memory usage optimization: Spent time optimizing packagefs memory usage last month. Changes include using singly-linked lists, dropping unused fields, inlining reference counts, eliminating padding, etc. Final result is around 20% (or more) savings in packagefs memory usage (excluding file data caches, at least 15 MB on the system). Also replaced default string hashing routine with
hashdjb2

- Tracker: jscipione cleaned up code and fixed Deskbar and Tracker to use "Menu" font. OscarL fixed a Tracker crash on screen resolution changes. humdinger widened text input column, and jscipione removed an extra prompt.
