Issues fixed in Scylla 4.1.2:

• CQL: Impossible WHERE condition returns a non-empty slice #5799
• Docker: add option to start Alternator with HTTPS. When using Scylla Docker, you can now use --alternator-https-port in addition to the existing --alternator-port. #6583
• UX: scylla-housekeeping, a service which check for the latest Scylla version, return “cannot serialize” error instead of propagating the actual error #6690
• UX: scylla_setup: on RAID disk prompt, typing same disk twice cause traceback #6711
• Stability: The concurrency control of the view update generation process was broken: instead of maintaining a constant fixed concurrency as intended, it could either reduce concurrency to almost 0, or increase it towards infinity #6774
• Stability: Counter write read-before-write is issued with no timeout, which may lead to unbounded internal concurrency if the enclosing write operation timed out. #5069
• Scylla crashes when CDC Log is queried with a wrong stream_id #6570

Issues fixed in Scylla 4.1.1:

• CQL: Using LWT (INSERT ...IF NOT EXISTS) with two or more tables in a BATCH may cause boost::dynamic_bitset assertion #6332
• Alternator: PutItem should output empty map, not empty JSON, when there are no attributes to return #6568
• Alternator: missing UnprocessedKeys/Items attribute in BatchGetItem/WriteItems result #6569
• UX: cql transport report a broken pipe error to the log when a client closes its side of a connection abruptly #5661
• Storage: SSTable upgrade has a 2x disk space requirement #6682
• Stability: Scylla freezes when casting a decimal with a negative scale to a float #6720
• Alternator: modifying write-isolation tag is not propagated to a node of another DC #6513
• Stability: Stream ended with unclosed partition and coredump #6478
• Stability: oversized allocation when calling get token range API, for example during a Scylla Manager initiate repair #6297
• Build: gdb cannot find shared libraries #6494
• Stability: In a case when using partition or clustering keys which have a representation in memory which is larger than 12.8 KB (10% of LSA segment size), linearization of the large (fragmented) keys may cause undefined behavior #6637
