Issues solved in this release:

Stability: Scylla may hang or even segfaults when querying system.size_estimates #4689

Stability: Potential undefined behavior in sstables cleanup, which may cause a segmentation fault #4718

Stability: Catch SSTable unclosed partition format error in the write path, not in the read path. A new command line flag: --abort-on-internal-error make Scylla exit as soon a such an error occurs, making it easier to catch and debug. #4786

Scylla try to stop view builder even if it is disabled, resulting in a core dump #4589

Time Window Compaction Strategy: on some very rare cases, a use after free may hurt performance #4465

Stability: In some cases, when --abort-on-lsa-bad-alloc is enabled, Scylla aborts even though it’s not really out of memory #2924
