MongoDB 4.4.23-rc0 is out and is ready for testing. This is a release candidate containing only fixes since 4.4.22. The next stable release 4.4.23 will be a recommended upgrade for all 4.4 users.
Fixed in this release:
SERVER-73943 Pin code pages in memory in memory constrained systems
SERVER-75922 Partial unique indexes created on MongoDB 4.0 can be missing index keys after upgrade to 4.2 and later, leading to uniqueness violations
SERVER-78126 For specific kinds of input, mongo::Value() always hashes to the same result on big-endian platforms
As always, please let us know of any issues.
