| only authenticated and authorized users. |

| memory, heap corruption and potentially remote code execution. Specifically: |
| using COMMAND GETKEYS* and validation of key names in ACL rules. |

| Redis 7.2 RC1 Released Wed Mar 22 12:00:00 IST 2023 |
| ================================================================================ |
|
|
| Upgrade urgency LOW: This is the first Release Candidate for Redis 7.2. |
|
|
| Redis Release Candidate (RC) versions are early versions that are made available |
| for early adopters in the community to test them. We do not consider |
| them suitable for production environments. |
|
|
| Introduction to the Redis 7.2 release |
| ===================================== |
|
|
| Redis 7.2 includes optimizations, several new commands, some improvements, |
| bug fixes, and several new module APIs. |
|
|
| In particular, users should be aware of the following changes: |
|
|
| 1. Redis 7.2 uses a new format (version 11) for RDB files, which is incompatible |
| with older versions. |
| 2. See section about breaking changes mentioned below. |
| 3. If you use modules, see the module API breaking changes section below. |
|
|
| Here is a comprehensive list of changes in this release compared to 7.0.10. |

| at https://github.com/redis/redis/pull/<number> |

| different error code (#11012) |
| * Command stats are updated for blocked commands only when / if the command |
| actually executes (#11012) |
