| # Incompatible Changes between EMQX 5.x and EMQX 6.0 | ||
|
|
||
| ## Deprecated Packages | ||
|
|
||
| - [#15939](https://github.com/emqx/emqx/pull/15939) Stopped releasing packages for systems that have already reached end-of-life: | ||
| - Debian 10 (Buster) | ||
| - Enterprise Linux (CentOS) 7 | ||
| - Ubuntu 18.04 | ||
| - Ubuntu 20.04 | ||
| - macOS 13 (Ventura) | ||
|
|
||
| - [#16050](https://github.com/emqx/emqx/pull/16050) Stopped releasing packages for Amazon Linux 2. It will reach end-of-life on June 30, 2026. | ||
|
|
||
| ## Durable Sessions | ||
|
|
||
| If the durable sessions feature was not enabled before, you can ignore this section. | ||
|
|
||
| In EMQX 6.0, the internal representation of durable sessions and their messages has changed. | ||
| Clusters previously running on version 5.x with durable sessions enabled must be recreated from a clean state when upgrading to 6.0. | ||
|
|
||
| For detailed upgrade instructions, see the [rolling upgrade documentation](../deploy/rolling-upgrades.md#emqx-enterprise-rolling-upgrade). | ||
|
|
||
| - [#15496](https://github.com/emqx/emqx/pull/15496) The state of durable sessions has been migrated from Mnesia to a new database built on EMQX durable storage. | ||
| - As a result, all durable session states created before 6.0.0 will be lost during the migration. | ||
| - This change resolves potential session state corruption caused by Mnesia’s limited transaction isolation (see [#14039](https://github.com/emqx/emqx/issues/14039)). | ||
| - It also improves the performance and scalability of durable sessions through sharding and a more efficient data representation. | ||
|
|
||
| ## Will Message Behavior | ||
|
|
||
| Authorization checks for durable sessions are now performed at the moment of client disconnection to determine whether the will message may be published. | ||
|
|
||
| Previously, these checks were deferred until after the configured `Will-Delay-Interval` had expired. | ||
|
|
||
| ## Configuration Changes | ||
|
|
||
| **Durable Sessions** | ||
|
|
||
| - `durable_storage.messages.n_sites` parameter has been renamed to `durable_storage.n_sites`. This parameter has become common for all durable storage. | ||
| - `durable_storage.sessions` and `durable_storage.timers` have been added. | ||
| - [#15734](https://github.com/emqx/emqx/pull/15734) Improved the reliability and throughput of durable sessions. | ||
|
|
||
| **Durable Storage** | ||
|
|
||
| - `durable_storage.messages.n_sites` has been renamed to `durable_storage.n_sites`, which now applies to all durable storage types. | ||
| - Added new configuration entries for `durable_storage.sessions` and `durable_storage.timers`. | ||
|
|
||
| **RocketMQ** | ||
|
|
||
| - [#15635](https://github.com/emqx/emqx/pull/15635) The `parameters.strategy` field no longer accepts key templates (which previously implied the `key_dispatch` strategy). | ||
| Instead, set `parameters.strategy = key_dispatch` explicitly and specify the key template in `parameters.key`. | ||
|
|
||
| **Platform Support** | ||
|
|
||
| - [#15613](https://github.com/emqx/emqx/pull/15613) Discontinued package builds for Debian 10. | ||
|
|
||
| ## Rate Limit | ||
|
|
||
| - [#15743](https://github.com/emqx/emqx/pull/15743) Listener connection rate limits (`max_conn_rate` and `max_conn_burst`) are now enforced per listener rather than per acceptor, restoring the behavior before 5.9.0. As a result, configurations from versions 5.9.0, 5.9.1, and 5.10.0 are incompatible: the specified rate values must be scaled up by the number of acceptors configured for each listener to preserve the same effective limits. |

| If you relied on the previous (incorrect) behavior, you may need to update your payload templates to ensure messages are formatted as expected. | ||

I reorganized the dir.yaml also. The "breaking-changes-6.0.0.md" includes changes between EMQX 5.x and EMQX 6.0, while "breaking-changes-6.0.md" includes changes in 6.0 series such as in 6.0.1, 6.1.0, 6.2.0....
