Uptime

Crash Client (Breakpad) Improvement

• Ted forked breakpad client to m-c, need to redo heap-in-minidump patches
• Consider to enable heap-in-minidump by default
• Thread-name patch got r+, still need Ted's review
• Need to file socorro bug for thread-name
• JS Stack - gdb unwinder is not really helpful
• Risk: evaluating crashpad or reinvent crashpad, what's the advantage?

Windows Dynamic Analysis Improvement

• Experimenting adding a new automation build type
• Risk: only work on TaskCluster, will depends on the date we officially move to TC.
