MongoDB 4.2.2-rc1 is out and is ready for testing. This is a release candidate containing only fixes since 4.2.1. The next stable release 4.2.2 will be a recommended upgrade for all 4.2 users.

Fixed in this release:
  • SERVER-31083 Allow passing primary shard to "enableSharding" command for a new database
  • SERVER-33272 The DatabaseHolder::close() function no longer requires a global write lock and neither does the dropDatabase command
  • SERVER-44050 Arrays along 'hashed' index key path are not correctly rejected
  • SERVER-44617 $regexFind crash when one of the capture group doesn't match the input but pattern matches
  • SERVER-44721 Shell KMS AWS support cannot decrypt responses
  • WT-4961 Checkpoints with cache overflow must keep history for reads
  • WT-5218 Improve eviction to differentiate between clean and dirty pages with WT_CACHE_EVICT_NOKEEP readgen
