Issues fixed in this release:

Stability: Docker image fails to run Alternator with HTTPS. #10025
Performance: Long-term index caching in the global cache, as introduced in 4.6, hurts the performance for workloads where accesses to the index are sparse. To mitigate this, a new configuration parameter cache_index_pages (default true) is introduced to control index caching. Setting the flag to `false` causes all index reads to behave like they would in BYPASS CACHE queries. Consider using false if you notice performance problems due to lowered cache hit ratio in 4.6 or 5.0. The config API can update the parameter live (without restart). #11202
Stability: Some shards get stuck in tight loop during repair #11223. This is a regression introduced in ScyllaDB 5.0
Stability: lack of mutation associativity which manifests as sporadic failures in row_cache_test.cc::test_concurrent_reads_and_eviction #11312
Stability: Messaging service misconfigured tcp_nodelay for verbs. The result is gossiper messages are coming with increased latency. This may affect the nodes status visibility of each other and, which is worse, there’s an increased chance of one node marking the alive peer as dead #11465
Alternator Stability: Invalid alternator_encryption_options in scylla.yaml causes ScyllaDB to coredump. #11520
Tools: scylla sstable --help is broken #11571
