### Modules API

- #14445 Allow modules to associate metadata with keys
  - `RedisModule_CreateKeyMetaClass` - define a new key-metadata class
  - `RedisModule_ReleaseKeyMetaClass` - release a key-metadata class
  - `RedisModule_SetModuleMetadata` - attach or update metadata to a key
  - `RedisModule_GetKeyMeta` - get key metadata

### Metrics

- #14896 `INFO STATS` - global stats for slowlog metrics:
  - `slowlog_commands_count` - commands written to slowlog
  - `slowlog_commands_time_ms_sum` - sum of execution times of commands from the slowlog
  - `slowlog_commands_time_ms_max` - maximum execution time of a command from the slowlog
- #14896 `INFO COMMANDSTATS` - per-command stats for slowlog metrics:
  - `slowlog_count` - number of times the command was written in the slowlog
  - `slowlog_time_ms_sum` - sum of execution time of the command (only from the slowlog)
  - `slowlog_time_ms_max` - maximum execution time of the command (only from the slowlog)
- #14841 `INFO STATS` (global, all clients aggregated):
  - `total_client_processing_events`: attempts to process client input buffers; does not guarantee any command was actually parsed
  - `eventloop_cycles_with_clients_processing`: event loop cycles where client input buffers were processed
  - `commands_per_parse_batch_sum`: cumulative number of commands parsed across all parsing batches for all clients
  - `commands_per_parse_batch_cnt`: number of parsing batches across all clients. A batch is counted each time at least one command is parsed from a client's query buffer
  - `commands_per_parse_batch_avg`: average commands parsed per batch (sum/cnt). Approximates pipelining depth
- #14841 `CLIENT INFO` and `CLIENT LIST` (per-client):
  - `read-events`: number of read events for this client
  - `parse-batch-cmd-sum`: cumulative number of commands parsed across all parsing batches for this client
  - `parse-batch-cnt`: total number of parsing batches for this client. Divide `parse-batch-cmd-sum` by this value to get the client’s average commands per batch

### CLI tools

- #14371 Divide-by-zero in redis-benchmark and redis-cli
- #14863 Memory leak in redis-cli

- Hot keys detection and reporting; new command: `HOTKEYS`
- TLS certificate-based automatic client authentication
- Time series: support NaN values; new aggregators: `COUNTNAN` and `COUNTALL`
