The release contains new features, minor enhancements, and bug fixes including:
Agent 6.27.1
Adds macOS 12 (x86_64) as a supported Agent platform
Allows use of puppet certificate for client HTTPS authentication with external CAs
PuppetDB 6.21.0
Ubuntu 20.04 and SUSE Linux Enterprise 15 are now supported.
PuppetDB will no longer run a garbage collection on startup. This may substantially reduce the time required before PuppetDB begins accepting commands and queries.
PuppetDB should require much less time and memory when parsing some PQL queries
The fact path GC now runs no more than once every 24 hours by default. This should be much less expensive in most cases, in exchange for a potentially slower response to the disappearance of individual fact paths.
Server 6.19.0
Adds SUSE Linux Enterprise 15 as supported Server platform
Server CA now supports using a type 2 key identifier
