Bug Fix

• Fix leftover default connection pool construction in
  blocking cluster connection pool

Chores

• Reduce excessive matrix in default CI
• Add scheduled compatibility CI run
• Cleanup unnecessary asyncio markers in tests
• Refactor readonly command detection to use
  command flags from redis documentation
• Issue warning if Redis.select is
  called directly

Bug Fix

• Ensure default cluster connection pools are not recreated upon access. #92

Bug Fix

• Implicitly initialize cluster connection pool when pubsub subscribe is called (#88)
• Fix handling of sharded pubsub unsubscribe message
• Fix unsubscribe all for sharded pubsub

Compatibility

• Improve surfacing underlying errors when initializing cluster (#89)

Bug Fix

• Fix context leak when commands issued within ensure_replication and ignore_replies context managers fail

Recipes

• Fix LUA lock recipe to work with clusters with no replicas.
• Ensure LUA lock recipe waits on replication of lock to n/2 replicas if replicas exist in the cluster

Compatibility

• Bring back python 3.7 support

Breaking changes

• Default nodemanager_follow_cluster to True

Deprecations

• Deprecate readonly constructor argument in
  cluster client in favor of read_from_replicas

• Remove invalid property setter for noreply mode

Bug Fixes

• Fix incorrect behavior of ignore_replies context manager
  as it was not actually setting CLIENT REPLY and simply
  discarding connections
• Ensure fetching a random connection doesn't deplete the
  node list in the connection pool
• Ensure connection pools are disconnected on finalization
  to avoid leaking connections

Bug Fix

• Fix incorrect calculation of per node connection pool size in BlockingClusterConnectionPool when readonly=False
• Ensure max_connection is at least equal to the number of nodes in the cluster and raise a warning when it is not

Features

• Allow passing connection_pool_cls to Redis and RedisCluster constructors to pick
  the connection pool implementation during client construction

Breaking Changes

• Raise coredis.exceptions.ConnectionError instead of coredis.exceptions.RedisClusterError
  when a connection can't be acquired due to max_connections being hit.

Compatibility

• Add support and test coverage for PyPy 3.8.

Bug Fix

• Ensure coredis.RedisCluster.ensure_replication can be used
  with ~coredis.RedisCluster.ensure_replication.replicas <
  total number of replicas

Bug Fix

• Fix routing of coredis.Redis.script_kill and coredis.Redis.function_kill to only route to primaries
• Ensure all arguments expecting collections consistently use coredis.typing.Parameters

Chores

• Fix ordering of keyword arguments of coredis.Redis.set to be consistent with command documentation
• Improve documentation regarding request routing and repsonse merging for cluster multi node and multi shard commands
• Sort all literal annotations

Bug Fix

• Ensure lua scripts for lock recipe are included in package

Features

• Reintroduce distributed lock implementation under
  coredis.recipes.locks

Bug Fix

• Allow initializing a LUA library without loading the code
  when it already exists if replace=False

Performance

• Reduce unnecessary calls to parser by using an async Event
  to signal that data is available for parsing

Compatibility

• Relax version checking to only warn if a server reports
  a non standard server version (for example with Redis-like
  databases)
• Raise an exception when client tracking is not available
  and server assisted caching cannot be used (for example
  with upstash provisioned redis instances)

Documentation

• Add more detail about Sharded Pub/Sub

Documentation

• Added section about reliability in handbook
• Improved cross referencing

Features

• Added support for using noreply when sending commands
• Added support for ensuring replication to n replicas
• Moved KeyDB client out of experimental namespace

Backward incompatible changes

• Use RESP3 as default protocol version
• non_atomic_cross_slot is default behavior for cluster clients
• Moved exceptions out of root namespace to coredis.exceptions
• Removed Lock implementations
• Dropped support for hiredis
• Removed StrictRedis & StrictRedisCluster aliases

Chore

• Remove python 3.11 binary wheel builds

Bug Fix

• Fix issue with sharded pubsub not handling multiple channel
  subscriptions

Bug Fix

• Correct implementation of restore command when
  absttl argument is True.

Bug Fix

• Ignore case when comparing error strings to map exceptions. Addresses #70

Bug Fix

• Fix incorrect handling of non_atomic_cross_slot commands
  when not all nodes are required for a command
