* Fixed a bug causing crash if keys command is called after a blocking command (Fixes issues #659, #605, #532)

* Fixed double free bug in lazy free
* Added "overload-protect-percent" config, when enabled this will load shed clients whenever CPU usage exceeds configured value
* Added "availability-zone" config, this can be passed any string which will then be reported by info command

* Fixed a possible deadlock when running CLIENT KILL with large number of clients

* Fixed a bug causing forked processes to hang, specifically affecting RDB and AOF(Fixes issues #675, #619)
* Added "CLUSTER REPLICATE NO ONE" to turn a replica into an empty primary
* Added RDB-less full sync, can be enabled with config 'enable-keydb-fastsync'
* Added "flash-disable-key-cache" config to disable key cache which stores every key(but not value) in memory
* Moved cluster slot to key map to being stored by storage provider, rather than in memory
* Moved expires to be stored by storage provider, rather than in memory
* Enabled expiry/eviction from storage provider, previously only data stored in memory could be expired/evicted(Fixes #645 along with the 2 previous updates)
* Fixed a bug where swapdb result was not recovered after keydb restarts in FLASH mode (Thanks to @karthyuom)
* Fixed double free bug when fast sync was canceled early
* Fixed a bug where a temp rdb file with zero bytes is generated in flash mode (Thanks to @karthyuom)
* Fixed a bug where flash CF options are being reset to default after flushall (Thanks to @karthyuom)(Fixes issue #717)

* To help accelerate our development efforts for KeyDB, this will be the last release containing support for Centos 7, Ubuntu 16.04, Ubuntu 18.04, Debian 9 and 32-bit builds
* This release contains fixes for 11 issues along with improvements to the KeyDB FLASH feature:
* Fixed race condition with expireset access (Issue #597)
* Fixed keys command with lua, and added keydb as an alternative to redis as lua variable to access db (Issue #562 and #594)
* Fixed hang in aof child (Issue #554)
* Fixed leaking fds from RDB save (Issue #453 and #584)
* Added config for S3 RDB load/save (Issue #584)
* Enabled active defrag during forkless background save to improve average memory efficiency (Issue #460)
* Fixed crash with fork background save during replication (Issue #567)
* This release contains Beta level support for KeyDB FLASH, new ASYNC commands, latency improvements and a number of bug fixes.
* KeyDB FLASH is included as a Beta feature. FLASH allows KeyDB to persist data to the storage medium it is written to, avoiding the need for AOF/RDB files. KeyDB uses rocksdb as the persistent storage provider and can be enabled with config "storage-provider flash /path/to/rocksdb/output". Read more at https://docs.keydb.dev/docs/flash/
* In addition to GET/MGET, ASYNC support has been added for the following commands: HGET, HMGET, HKEYS, HVALS, HGETALL, HSCAN and can be enable with config "enable-async-commands yes”
* Packaging support for Ubuntu 22.04 (Jammy) and Debian 12 (Bookworm) has been included with this release
* Added new soft shutdown feature, can be enabled with config "soft-shutdown yes".
* If soft shutdown is enabled, instead of shutting down right away, the server will wait until all clients have disconnected, and will reject all new connection attempts.
* Fixed memory leak with tls certificates when tls allowlist is enabled
* Fixed bug in rdb load with flash enabled to ensure all dbs are safe to load (previously only checked db[0])
* Fixed race conditions in rdb load and replication
* Fixed memory access of rdb file after it should have been deleted
* Fixed integer overflow bug in flash(Issue #486)
* Improve TLS latency by queueing new commands before executing instead of after
* Removed O(n) count of memory usage from info command(replaced by O(1) estimate)
* Improved latency of clearing large number of flash DBs(Thanks to Paul Chen for this fix)(Issue #516)
* replaced sprintf with snprintf to avoid potential security bugs
* Fixed bug where a failed move due to key already existing in move target would result in the key being removed from move source(Thanks to Paul Chen for this fix)(Issue #497)
* Fixed usage of deprecated OpenSSL api in OpenSSL v>3.0.1(Issue #392)
* Imported security fixes from Redis (CVE-2023-22458 CVE-2022-35977)
* 6.0.16 - This release contains significant performance improvements as well as fixes to the following issues: #234, #236, #233, #207, #229, #231
* Reduced memory consumption when Active Replication is not used
* Reduced CPU consumption
* Improved TLS performance
* replica-quorum config for multi-master.Intended to be used with "replica-serve-stale-data no", if at least N replicas are connected we will consider our master link up and serve data.
* Subkey expires performance improvement for big sets

* Fixed Issues: 194 Bad directive or wrong number of arguments error on 'lazyfree-lazy-user-del no'; 209 Timeout using modules; 210 Databases are not merged on multi-master sync; 211 rpm packages now signed; 212 rpm file permissions updated

* This is our first release to fully support all Redis 6.0.4 features, including but not limited to: TLS Support (fully supports multithreading!), Client side caching, RESP 3 Support
* KeyDB Has also added the following new features: Improved memory efficiency for short strings, Fastlock autotuning, KeyDB.HRENAME (rename a member of a hash)In addition we've spent a lot of time focussing on stability.
* The following bug fixes are resolved: 150 - Deadlock in ReplicationFeedMonitors, 170 - KeyDB dying via SIGABORT, 180 - crash after setting maxclients via cmd line, 169 - Write performance of a master dropped sharply when a replica is added
* In addition untracked issues were resolved: Potential deadlock when entering futex sleep, Pub/Sub Async messages may not be sent in a timely manner when load is low, Excessive logging during failed RREPLAY, KeyDB unresponsive handling clients on different threads during RDB load
* Updated deb package builds to build from source and phasing out init.d. dh_installsystemd from deb helper 11 used where applicable
* Naming conventions are now updated [ keydbpackage_version-build~distribution_architecture] and master changelog included and maintained
* keydb-pro-server binary is no longer inluded in the open source package
-- Ben Schermel <ben@eqalpha.com> Mon, 1 Jun 2020 8:00:37 +0000
* 5.1 release. This release includes subkey expires (EXPIREMEMBER/EXPIREMEMBERAT), with updates to PTTL/TTL accordingly. New OBJECT LASTMODIFIED, BITIOP LSHIFT & BITOP RSHIFT commands. See https://docs.keydb.dev/blog/2019/10/20/blog-post/ for detailed review of release.
