+- Use updated stored ask API (https://github.com/filecoin-project/lotus/pull/4384)
+- tvx: trace puts to blockstore for inclusion in CAR. (https://github.com/filecoin-project/lotus/pull/4278)
+- Add propose remove (https://github.com/filecoin-project/lotus/pull/4311)
+- Update to 0.9.1 bugfix release (https://github.com/filecoin-project/lotus/pull/4402)
+- Update drand endpoints (https://github.com/filecoin-project/lotus/pull/4125)
+- fix: return true when deadlines changed (https://github.com/filecoin-project/lotus/pull/4403)
+- sync wait --watch (https://github.com/filecoin-project/lotus/pull/4396)
+- reduce garbage in blockstore (https://github.com/filecoin-project/lotus/pull/4406)
+- give the TimeCacheBS tests a bit more time (https://github.com/filecoin-project/lotus/pull/4407)
+- Improve gas defaults (https://github.com/filecoin-project/lotus/pull/4408)

+- fix(sync state): set state height to actual tipset height (https://github.com/filecoin-project/lotus/pull/4347)
+- Fix off by one tipset in searchBackForMsg (https://github.com/filecoin-project/lotus/pull/4367)
+- fix a panic on startup when we fail to load the tipset (https://github.com/filecoin-project/lotus/pull/4376)
+- Avoid having the same message CID show up in execution traces (https://github.com/filecoin-project/lotus/pull/4350)
+- feat(markets): update markets 0.9.0 and add data transfer restart (https://github.com/filecoin-project/lotus/pull/4363)

 ## Reporting a Vulnerability

-For *critical* bugs, please send an email to security@filecoin.org.
-
-The bug reporting process differs between bugs that are critical and may crash the network, and others that are unlikely to cause problems if malicious parties know about it. For non-critical bugs, please simply file a GitHub [issue](https://github.com/filecoin-project/lotus/issues/new?template=bug_report.md). 
+For *critical* bugs, please consult our Security Policy and Responsible Disclosure Program information at https://github.com/filecoin-project/community/blob/master/SECURITY.md

 Please try to provide a clear description of any bugs reported, along with how to reproduce the bug if possible. More detailed bug reports (especially those with a PoC included) will help us move forward much faster. Additionally, please avoid reporting bugs that already have open issues. Take a moment to search the issue list of the related GitHub repositories before writing up a new report.
