Upgrade urgency LOW: Initial release of Valkey with API compatibility for OSS
Redis 7.2.4. This release is based off of OSS Redis 7.2.4, with additional
functionality to better brand the server as Valkey instead of Redis. All APIs
are fully backwards compatible and care was taken to minimize the number of
log lines that were changed to best support existing tooling around log parsing.

Changes to support Valkey branding

• Rename the 6 Redis binaries to ones with valkey prefixes: valkey-server,
  valkey-cli, valkey-benchmark, valkey-check-aof, valkey-check-rdb and
  valkey-sentinel. (#62)
• During install, create symlinks mapping the corresponding Redis binary names
  to the new Valkey binaries. (#193)
• INFO fields: Introduce valkey_version and server_name fields. The
  redis_version will continue to be present and will indicate the Redis OSS
  version that the server is compatible with. (#47, #232)
• RDB file format: Introduce a valkey-ver RDB field to indicate an RDB file
  was produced by a Valkey server. This field is ignored when the file is
  loaded by Redis OSS. (#47)
• Module API changes: Introduce Valkey Module API in a new file, valkeymodule.h,
  with functions and types prefixed by ValkeyModule. Valkey is still fully ABI
  compatible with the Redis Module API, meaning Valkey supports running modules
  compiled with either the Redis or Valkey Module APIs. For full source
  compatibility, the Redis Module API (redismodule.h) is also kept with the
  RedisModule prefixed functions and types. (#194, #243, #262)
• Scripting: Introduce a new top level server object for functions and scripts
  that can be instead of the existing redis object. This allows users to
  replace calls like redis.call(...) with server.call(...). (#213)
• Makefile: Introduce SERVER_CFLAGS and SERVER_LDFLAGS as an alternative to
  REDIS_CFLAGS and REDIS_LDFLAGS. (#46)
• Update template config files to replace references to Redis with Valkey. The
  file valkey.conf replaces redis.conf. (#29, #171)
• Logging: Update startup, shutdown, and help logs to reference Valkey instead of
  Redis. Valkey server will also show the Valkey logo at startup and show the
  Valkey repositories when crashing. (#251, #252, #263, #113)

Bug fixes

• Cluster: Fix an issue where cluster nodes running on Redis versions earlier
  than 7.0 would be unable to communicate with nodes running on Valkey 7.2. This
  change also introduces a slight delay when hostnames are not displayed when a
  node is first added to the cluster. (#52)
