Releases

13.0.13 Aug 2026Security
Upgraded Snappier to 1.3.x to fix high severity vulnerability (GHSA-pggp-6c3x-2xmx)
v13.0.1:

Performance: connection pool selection no longer allocates multiple ServerCounters snapshots per operation (LeastLoaded) and uses a true lock-free round-robin instead of a cryptographic RNG (RoundRobin)

Performance: RedisDatabase instances are cached per database number instead of being allocated on every Db0..Db16 access

Performance: HashGetAsync multi-key now issues a single HMGET instead of N parallel HGET round-trips

Performance: UpdateExpiryAsync no longer issues a redundant EXISTS before EXPIRE (half the round-trips)

Performance: AddAllAsync builds its payload without LINQ intermediate materializations

Performance: eager materialization of previously lazy IEnumerable results (SetPopAsync, SortedSetRangeByScoreAsync, HashKeysAsync, SearchKeysAsync) — no more re-deserialization on repeated enumeration

Performance: serializers (Newtonsoft, ServiceStack, MsgPack, Protobuf) no longer materialize intermediate UTF-16 strings or wrapping MemoryStreams

Performance: compressors use pooled buffers (Snappier, Brotli, ZstdSharp) and reused Zstd contexts; Snappier.Decompress no longer duplicates the output array

Performance: IDistributedCache adapter uses cached field arrays and batches HSET+EXPIRE in a single network write

Fixed HashGetAllAsyncAtOneTimeAsync applying KeyPrefix to hash fields instead of the hash key, and removed a potential Lua injection through the hash key

Fixed Utf8JsonSerializer.Deserialize throwing on null input instead of returning default

Fixed ListGetFromRightAsync duplicated null check (dead code)

Additional notes

Patch release: full-codebase performance pass with zero public API changes, plus three bug fixes found during the audit. Compatible drop-in upgrade from v13.0.0.

⚡ Performance

Connection pool (hot path of every operation)

LeastLoaded no longer re-evaluates TotalOutstanding() per comparison — each call allocated a ServerCounters snapshot in SE.Redis, up to ~9 per single Redis operation with the default pool size. Now at most one call per pooled connection.
Debug log arguments are no longer evaluated when logging is disabled (one more GetCounters() saved per operation).
RoundRobin now uses a lock-free Interlocked counter: previously it used a cryptographic RNG on net6+ and allocated new Random() per call on netstandard2.1 — and wasn't actually round-robin.
Removed a static lock held during blocking connection creation that serialized pool startup process-wide with multiple named clients.

Core

Db0..Db16 / GetDefaultDatabase() no longer allocate a new RedisDatabase on every access — instances are cached per database number.
HashGetAsync(hashKey, string[]) issues a single HMGET instead of N parallel HGET round-trips.
UpdateExpiryAsync drops the redundant EXISTS pre-check before EXPIRE — half the round-trips, N-fold for UpdateExpiryAllAsync.
AddAllAsync builds its payload in one pre-sized pass instead of a LINQ pipeline with growth buffers.
SetPopAsync(count), SortedSetRangeByScoreAsync, HashKeysAsync, SearchKeysAsync now materialize results eagerly — previously a lazy Select re-deserialized (or re-allocated) everything on each enumeration.
Tag writes serialize the key once instead of once per tag.
Pub/Sub message handling drops ~half its per-message allocations (ContinueWith continuation removed).

Serializers

Newtonsoft and ServiceStack no longer materialize every payload as an intermediate UTF-16 string (~2× the bytes, LOH for large payloads); Newtonsoft also caches its JsonSerializer and pools char buffers.
MsgPack and Protobuf drop their wrapping MemoryStreams.
System.Text.Json, MemoryPack, Utf8Json were already optimal.

Compressors

Snappier: Decompress no longer duplicates the output array (the copy was 100% redundant); Compress rents its transient worst-case buffer from ArrayPool.
Brotli: one-shot BrotliEncoder.TryCompress replaces the stream pipeline.
ZstdSharp: compression contexts are now reused per thread instead of being created per call — the main zstd anti-pattern — plus exact-size decompression.
GZip: pre-sized buffers.

ASP.NET Core

IDistributedCache adapter: cached field arrays (no per-Get allocation) and batched HSET+EXPIRE in a single network write on SetAsync.

🐛 Bug fixes

HashGetAllAsyncAtOneTimeAsync with KeyPrefix: the per-call Lua script embedded the hash key unprefixed while wrongly prefixing the hash fields — with a prefix configured the method read the wrong hash. The script was also a Lua injection vector and defeated the server-side script cache. Replaced by HMGET.
Utf8JsonSerializer.Deserialize(null) threw instead of returning default, unlike every other serializer.
ListGetFromRightAsync had a duplicated null check (dead code).

Behavioral notes

HashGetAsync(string[]) returns a Dictionary instead of ConcurrentDictionary (contract is IDictionary<string, T?>).
RoundRobin selection is now sequential instead of random.
Pub/Sub handler errors log the original exception instead of the wrapping AggregateException.

StackExchange.Redis 3.x Compatibility (#656)

Core package now accepts StackExchange.Redis [2.12.14, 4.0.0), ensuring forward compatibility with the upcoming SE.Redis 3.x releases.

Code Quality

Removed orphaned ICacheSerializationContext interface (unused since 2022)
Cleaned up Visual Studio merge-tool comment artifacts
Removed unused using directives
Renamed RedisKeyHelper.cs → GenericsExtensions.cs to match actual class name
Updated CI to use redis:8 Docker image (Redis 8.10.0 stable)

Documentation

New documentation pages: HyperLogLog, Distributed Lock, Bitmap, Lua Scripting
Migration guide v12 → v13
Created llms-full.txt for comprehensive AI assistant documentation
Updated README with new feature examples and usage sections

Test Coverage

1754 tests passing on net10.0 (up from 1635 in v12.6.0). All tests pass across net10.0 and net9.0.

Breaking Changes

None for consumers using IRedisDatabase through DI. If you have a custom implementation of IRedisDatabase, you will need to add the new methods — see the migration guide.

Bug Fix

Fixed Pub/Sub UnsubscribeAsync and UnsubscribeAllAsync not working with connection pooling (#657)

When using connection pooling (default pool size: 5), UnsubscribeAsync and UnsubscribeAllAsync were each calling GetConnection() independently, potentially obtaining a different IConnectionMultiplexer than the one used during SubscribeAsync. Since StackExchange.Redis subscriptions are scoped to a specific multiplexer, calling unsubscribe on a different one was silently doing nothing.

The fix iterates all pool connections and uses ISubscriber.SubscribedEndpoint() to locate the multiplexer holding the active subscription.

Bug Fixes

SearchKeysAsync ignoring database number — SearchKeysAsync was using a raw SCAN command via IServer.ExecuteAsync which always defaults to database 0, regardless of which database instance (Db1, Db2, etc.) was used. Replaced with IServer.KeysAsync(database, pattern) which correctly targets the specified database. (#651)
RemoveByTagAsync not cleaning up tag keys — RemoveByTagAsync deleted all data keys referenced by a tag but never deleted the tag Set key itself (tag:{tagName}), causing empty Redis Sets to accumulate indefinitely. The tag key is now deleted after removing its members. (#650)
