+## Versioning and Maintenance
 
-### Bug fixes
+Phlex does not follow semantic versioning. Instead, we use the following scheme:
 
-- Only the latest minor version of each major version will receive bug fixes
-- We may choose to fix bugs by releasing a new minor version rather than patching the existing minor version
-- Major versions will stop receiving bug fixes one year after the next major version is released
+```
+DISRUPTIVE.INCOMPATIBLE.COMPATIBLE
+```
 
-### Security patches
+- `DISRUPTIVE`: This is for milestone/announcement releases and/or major changes that are not backwards compatible and will likely require some work to upgrade.
+- `INCOMPATIBLE`: This is for changes that are not backwards compatible and may require a little work to upgrade.
+- `COMPATIBLE`: This is for bug fixes, new features and security patches that are non-breaking.
 
-- When a security issue is brought to our attention, we aim to release patches for any minor version that was released in the last year.
-- Additionally, the latest minor version of the latest major version will receive security patches, even if that version is over a year old.
+When a security issue is brought to our attention, we aim to release patches as soon as possible. We aim to patch with a new `COMPATIBLE` version:
+
+- every `INCOMPATIBLE` version that was released in the last year;
+- the latest `INCOMPATIBLE` version of the latest two `DISRUPTIVE` versions, even if over a year old; and
+- the `main` branch in GitHub.
