[dependabot-preview]

Updates the requirements on redis to permit the latest version.

Changelog

Sourced from redis's changelog.

4.2.5

• Optimize the ruby connector write buffering. See #964.

4.2.4

• Fix bytesize calculations in the ruby connector, and work on a copy of the buffer. Fix #961, #962.

4.2.3

• Use io/wait instead of IO.select in the ruby connector. See #960.
• Use exception free non blocking IOs in the ruby connector. See #926.
• Prevent corruption of the client when an interrupt happen during inside a pipeline block. See #945.

4.2.2

• Fix WATCH support for Redis::Distributed. See #941.
• Fix handling of empty stream responses. See #905, #929.

4.2.1

• Fix exists? returning an actual boolean when called with multiple keys. See #918.
• Setting Redis.exists_returns_integer = false disables warning message about new behaviour. See #920.

4.2.0

• Convert commands to accept keyword arguments rather than option hashes. This both help catching typos, and reduce needless allocations.
• Deprecate the synchrony driver. It will be removed in 5.0 and hopefully maintained as a separate gem. See #915.
• Make Redis#exists variadic, will return an Integer if called with multiple keys.
• Add Redis#exists? to get a Boolean if any of the keys exists.
• Redis#exists when called with a single key will warn that future versions will return an Integer. Set Redis.exists_returns_integer = true to opt-in to the new behavior.
• Support keepttl ooption in set. See #913.
• Optimized initialization of Redis::Cluster. See #912.
• Accept sentinel options even with string key. See #599.
• Verify TLS connections by default. See #900.
• Make Redis#hset variadic. It now returns an integer, not a boolean. See #910.

4.1.4

• Alias Redis#disconnect as #close. See #901.
• Handle clusters with multiple slot ranges. See #894.
• Fix password authentication to a redis cluster. See #889.
• Handle recursive MOVED responses. See #882.
• Increase buffer size in the ruby connector. See #880.
• Fix thread safety of Redis.queue. See #878.
• Deprecate Redis::Future#== as it's likely to be a mistake. See #876.
• Support KEEPTTL option for SET command. See #913.

4.1.3
