v1.8.7

Added

• Agents can now be configured with an availability target, which establishes the minimum amount of time desired to gracefully handle server or agent downtime, influencing how aggressively X509-SVIDs should be rotated (#4599)
• SyncAuthorizedEntries RPC, which allows agents to only sync down changes instead of the entire set of entries. Agents can be configured to use this new RPC through the use_sync_authorized_entries experimental setting (#4648)
• Experimental support for an events based entry cache which reduces overhead on the database (#4379, #4411, #4527, #4451, #4562, #4723, #4731)

Changed

• The maximum number of open database connections in the datastore now defaults to 100 instead of unlimited (#4656)
• Agents now shut down when they can't synchronize entries with the server due to an unknown authority error (#4617)

Removed

• Agents no longer maintains agent SVID and bundle information in the legacy paths in the data directory (#4717)
