Breaking changes

• Use RESP3 (HELLO 3) by default; pass protocol: 2 to keep RESP2. GEOPOS and
  GEOSEARCH/GEORADIUS with WITHCOORD now return coordinates as Float instead of String.
  See specs/migration-resp3.md. (#​1351)
• Require Ruby 3.2+. (#​1353, #​1365)

New features

• Add support for the Redis Query Engine (RediSearch, FT.*): ft_create, ft_alter,
  ft_dropindex, ft_info, ft_search, ft_aggregate, vector and hybrid search, suggestions,
  dictionaries, synonyms, aliases, and spellcheck. Not supported by Redis::Distributed.
  (#​1356, #​1359, #​1360, #​1361)
• Add support for the JSON module: json_set, json_get, json_mset, json_mget, json_del,
  json_forget, json_clear, json_merge, json_arr*, json_obj*, json_str*,
  json_numincrby, json_toggle, json_type, json_debug_memory. (#​1346, #​1347, #​1348, #​1349)
• Add lmovem and blmovem (Redis 8.10). (#​1363)
• Add sunioncard and sdiffcard (Redis 8.10). (#​1357)
• xread and xreadgroup now accept max_count: and max_size: (Redis 8.10). (#​1358)
• Add hexpire, hpexpire, httl and hpttl (Redis 7.4). (#​1324, #​1325, #​1331)
• hscan and hscan_each now accept novalues: true (Redis 7.4). (#​1327)
• Add geosearch and geosearchstore (Redis 6.2); geo commands are now available on
  Redis::Distributed. (#​1342)
• geoadd now accepts nx:, xx: and ch:; geo radius searches accept count_any:; xadd
  accepts limit: (Redis 6.2). (#​1345)
• Redis::Distributed now implements hscan, hscan_each and hstrlen. (#​1319)
• Identify the client to the server via CLIENT SETINFO (lib-name=redis-rb,
  lib-ver=<version>). Extend the reported name with driver_info:, or disable with
  driver_info: false. See the README "Client identification" section. (#​1369)

Experimental

• Add himport_prepare, himport_set, himport_discard and himport_discard_all
  (Redis 8.10 HIMPORT). Lost fieldsets are re-prepared and retried automatically; disable with
  himport_auto_prepare: false. The API may change in a future minor release. See the README
  "Bulk hash ingestion (HIMPORT)" section. (#​1364)

Bug fixes

• Fix FloatifyPairs to not re-transform already transformed replies. (#​1354)
• unlink now returns 0 for an empty keyset, consistent with del. (#​1316)

Maintenance

• Pin redis-client to the exact version 0.30.1 (previously >= 0.22.0); includes the
  reply-desynchronization fix from 0.26.4. (#​1350, #​1352)
• Maintainership change: redis-rb is now maintained by the Redis Ltd company.
• Run the test suite against prebuilt redislabs/client-libs-test Docker images; CI now covers
  MRI 3.2/3.3/3.4/4.0 and TruffleRuby against Redis 7.2–8.10; JRuby removed. (#​1317, #​1318, #​1344)
• Drop the unused executables config from the gemspec. (#​1322)

v5.4.1

Compare Source

• Fix blmpop method to actually use BLMPOP, it was mistakenly issuing LMPOP commands.
• xadd now accepts a minid: argument.
• zrank and zrevrank now accepts with_score: argument.
• Redis#call now accept a block, allowing to use Redis instances where RedisClient is expected.

v5.3.0

Compare Source

• Fix the return type of hgetall when used inside a multi transaction which is itself inside a pipeline.

v5.2.0

Compare Source

• Now require Ruby 2.6 because redis-client does.
• Eagerly close subscribed connection when using subscribe_with_timeout. See #​1259.
• Add exception flag in pipelined allowing failed commands to be returned in the result array when set to false.

v5.1.0

Compare Source

• multi now accept a watch keyword argument like redis-client. See #​1236.
• bitcount and bitpos now accept a scale: argument on Redis 7+. See #​1242
• Added expiretime and pexpiretime. See #​1248.

v5.0.8

Compare Source

• Fix Redis#without_reconnect for sentinel clients. Fix #​1212.
• Add sentinel_username, sentinel_password for sentinel clients. Bump redis-client to >=0.17.0. See #​1213

v5.0.7

Compare Source

• Fix compatibility with redis-client 0.15.0 when using Redis Sentinel. Fix #​1209.

v5.0.6

Compare Source

• Wait for an extra config.read_timeout in blocking commands rather than an arbitrary 100ms. See #​1175.
• Treat ReadOnlyError as ConnectionError. See #​1168.

v5.0.5

Compare Source

• Fix automatic disconnection when the process was forked. See #​1157.

v5.0.4

• Cast ttl argument to integer in expire, setex and a few others.

v5.0.3

Compare Source

• Add OutOfMemoryError as a subclass of CommandError

v5.0.2

v5.0.1

Compare Source

• Added a fake Redis::Connections.drivers method to be compatible with older sidekiq versions.

v5.0.0

Compare Source

• Default client timeout decreased from 5 seconds to 1 second.
• Eagerly and strictly cast Integer and Float parameters.
• Allow to call subscribe, unsubscribe, psubscribe and punsubscribe from a subscribed client. See #​1131.
• Use MD5 for hashing server nodes in Redis::Distributed. This should improve keys distribution among servers. See #​1089.
• Changed sadd and srem to now always return an Integer.
• Added sadd? and srem? which always return a Boolean.
• Added support for IDLE paramter in xpending.
• Cluster support has been moved to a redis-clustering companion gem.
• select no longer record the current database. If the client has to reconnect after select was used, it will reconnect to the original database.
• Better support Float timeout in blocking commands. See #​977.
• Redis.new will now raise an error if provided unknown options.
• Removed positional timeout in blocking commands (BLPOP, etc). Timeout now must be passed as an option: r.blpop("key", timeout: 2.5)
• Removed logger option.
• Removed reconnect_delay_max and reconnect_delay, you can pass precise sleep durations to reconnect_attempts instead.
• Require Ruby 2.5+.
• Removed the deprecated queue and commit methods. Use pipelined instead.
• Removed the deprecated Redis::Future#==.
• Removed the deprecated pipelined and multi signature. Commands now MUST be called on the block argument, not the original redis instance.
• Removed Redis.current. You shouldn't assume there is a single global Redis connection, use a connection pool instead,
  and libaries using Redis should accept a Redis instance (or connection pool) as a config. E.g. MyLibrary.redis = Redis.new(...).
• Removed the synchrony driver.
• Removed Redis.exists_returns_integer, it's now always enabled.
