This release:

• Removes (previously deprecated) librpmem. Those interested in remote persistent memory support should use the rpma library (https://github.com/pmem/rpma).
• Removes libpmemset - it was an experimental library.
• Sets libpmemblk as deprecated, to be removed in the next release.
• Sets libpmemlog as deprecated, to be removed in the next release.
• Sets btt support as deprecated, to be removed in the next release.
• Sets async as deprecated, to be removed in the next release.
• Sets FreeBSD support as deprecated, to be removed in the next release.
• Sets Windows support as deprecated, to be removed in the next release.

Deprecations and removals are done accordingly to the support strategy outlined in the blog post: https://pmem.io/blog/2022/11/update-on-pmdk-and-our-long-term-support-strategy.

Other changes and notable bug fixes:

• core: handle ENOMEM gracefully during logging (#5515)
• pool: fix dependencies with pmempool (#5521)
• test: add more security checks for pmempool input
• pmreorder: share markers from an application through env variable (#5419)
• examples: fix potential buffer overflow in pmemobjfs example (#5472)
• several fixes to support ppc64le architecture
• several fixes for issues found by Coverity tool

Known issues:

• The latest validation cycle exposed previously unknown persistency issues related to pmem2 async functions (DEPRECATED) and miniasync (EXPERIMENTAL): #5596 and #5597. Both will be removed in the PMDK 1.14 release. These issues do NOT affect any other PMDK library.
