* We shipped a Firefox 37.0.1 desktop and mobile chemspills last week.
* Firefox 38 Beta 1 shipped last week.
* Updates have been re-enabled for Aurora.
* 5 weeks until the next merge date (2015-05-11).

Tree Closing Window on Saturday April 18, time TBD.

* at least 4-5 hours of work.
===MemShrink (njn)===
Brian Hackett took advantage of the removal of object parents to reduce the size of base shapes ({{bug|1143256}}). The JS engine creates many of these to track the characteristics of JS objects.
Nick Fitzgerald greatly reduced the amount of memory used for saving JS exception stacks ({{bug|1038238}}). This reduced the memory of a test case compiled from Dart to JS from over 1GB to around 170MB ({{bug|1125259}}).
Seth Fowler fixed a bad leak regression ({{bug|1150127}}) where closing a page while it was in the process of loading could leak the page and cause long browser pauses. Seth also fixed a pair of issues that caused very large memory usage (more than 1GB) when scrolling in the downloads list ({{bug|1148682}} and {{bug|1148684}}).
Bill McCloskey fixed an issue where a docshell was being held alive for too long on e10s ({{bug|1137933}}). This was one of the remaining blockers to enabling e10s Mochitest browser-chrome tests, which will give us more test coverage for leaks.
===Media===
We shipped MSE (Media Source Extensions) for YouTube in Firefox 37 on Windows Vista+. Unfortunately, we discovered multiple unrelated issues in the release channel that all manifest themselves as "video is black":
{{bug|1151721}}: Intel GPU driver bug (will be hotfixed by {{bug|1152630}})
{{bug|1151638}}: NoScript blocking MSE JS (will be fixed soon in NoScript 2.6.9.21)
{{bug|1135078}}: IPv6 problems (partially fixed {{bug|1135078}})
YouTube helped us quickly revert all Firefox users from HTML5 video to Flash. Once the problems were identified, YouTube was able to switch OS X and Windows Vista+ pre-channels back to HTML5 video. We plan to ship MSE for YouTube on Windows Vista+ in Firefox 38 (or 37 if hotfix {{bug|1152630}} is released soon) and on OS X in Firefox 38 (or possibly slip to 39).
