+## RabbitMQ 5.0.0
+
+RabbitMQ `5.0.0` is a new major release.
+
+See Compatibility Notes below to learn about **breaking or potentially breaking changes** in this release.
+
+
+## Breaking Changes and Compatibility Notes
+
+### `rabbitmq_amqp1_0` Plugin was Removed
+
+Since `4.0`, AMQP 1.0 has been a [core protocol](https://www.rabbitmq.com/blog/2024/08/05/native-amqp) that is always enabled, and the `rabbitmq_amqp1_0` plugin has been a no-op kept around only to simplify upgrades from `3.13.x` and earlier.
+
+Starting with `5.0.0`, the `rabbitmq_amqp1_0` plugin no longer ships with RabbitMQ. AMQP 1.0 support is unaffected: it continues to be enabled by default and does not require any plugin.
+
+Installations that still have `rabbitmq_amqp1_0` listed in their enabled plugins file **must remove it before upgrading**. This can be done using `rabbitmq-plugins disable rabbitmq_amqp1_0` or by removing the entry from `RABBITMQ_ENABLED_PLUGINS_FILE` directly.
+
+Clusters that upgrade without doing so will not fail to start: `rabbitmq-plugins list`, `enable` and `disable` will tolerate the now-missing plugin but will print a warning such as
+
+```
+WARNING - plugins currently enabled but missing: rabbitmq_amqp1_0
+```
+
+until the plugin is removed from the enabled plugins file.
