I’ve been diving into Linux and rapidly traversing through distributions finding things I like, don’t like, etc.
One thing I’m hung up on is that in “enterprise” operating systems (RHEL, CentOS, Alma, Rock, etc.) Apache is presently sitting at 2.4.37-43, while 2.4.51 is available from apache.org . I understand the last number (-43) would be a build increment of some form but what does being limited to 2.4.37 vs 2.4.51 mean from a practical and pragmatic standpoint?
Is the .37 release up to date with regards to critical security fixes/CVE disclosures, leaving out the features and development that went into later builds by Apache?
From what I can tell, this applies to virtually all “enterprise” packages so help me understand this package version convention.
