This document includes the new features, enhancements, and fixed issues since version 5.6.0.

Hazelcast Python Client v5.7.0 requires Python 3.11 or higher.

New Features

The asyncio client has reached General Availability (GA).
Added asyncio support for the following data structures and services:
- List (#782)
- ReplicatedMap (#783)
- MultiMap (#787)
- Queue (#788)
- Set (#789)
- Executor (#790)
- Ringbuffer (#796)
- Topic (#797)
- ReliableTopic (#802)
- PNCounter (#804)
- SQL (#808)
- FlakeIDGenerator (#809)
- AtomicLong (#814)
- AtomicReference (#815)
- CountDownLatch (#816)
- ISemaphore (#817)
- FencedLock (#818)
Lock APIs (Map, MultiMap, ISemaphore, FencedLock) are now fully enabled for the asyncio client using task-based IDs to distinguish concurrent async tasks. (#820)
Added the lock_context method to asyncio Map and MultiMap proxies. The lock_context method provides a context manager to automatically lock and unlock a key. See the corresponding example (#824)

Enhancements

Serialization performance improved by preallocating buffer space and reading/writing numeric array items in bulk rather than one by one. (#781)
Improved asyncio task cancellation handling. (#821)

Fixed a deadlock in the asyncio listener. (#777)
Fixed incorrect variable usage in cluster get_member. (#777)
Fixed missing task creation for conn.close_connection calls in asyncio. (#777)
Fixed incorrect retry methods in VectorCollection and blocking cloud discovery refresh in the asyncio client. (#777)
Fixed race conditions in ProxyManager.get_or_create and _handle_successful_auth in the asyncio client. (#780)
Fixed ConnectionManager.start_connect_all_members task handling. (#780)
Removed the write loop from the reactor. (#780)
Fixed VectorCollection.put_if_absent mutating the caller's document object. (#780)
