+# Release policies
+
+## Versioning
+
+Releases are organized in `<major>.<minor>.<patch>` style. A release is made
+about every week around tuesday-thursday. Releases increment the `minor` version
+number. Occasionally bug-fix releases occur after a weekly release. Those
+increment only the `patch` number. No releases have yet made a `major` version
+increment. Those are expected to be major releases that introduce large number
+of breaking changes.
+
+## Deprecation
+
+Changes to the public API are governed by a deprecation process in three stages.
+In the warning period of no less than _3 months_, the use of a deprecated
+package, module, or value will produce a warning but otherwise operate as
+expected. In the subsequent deprecated period of no less than _3 months_, the
+use of that component will produce an error after the deprecation message. After
+these two periods, the deprecated capability will be completely removed.
+
+!!! Info "Deprecation process"
+
+    - 3 months - warning
+
+    - 3 months - warning + error
+
+    - removal
+
+Changes that result in non-backwards compatible functionality are also reflected
+in the version numbering. In such cases, the appropriate level version change
+will occur at the introduction of the warning period.
+
+## Currently derpecating features
+
+- Starting 1.0.0, the `trulens_eval` package is being deprecated in favor of
+  `trulens` and several associated required and optional packages. See
+  [trulens_eval migration](/trulens/guides/trulens_eval_migration) for details.
+
+    - Warning period: 2024-09-01 with `trulens-eval` 1.0.0a0 -- 2024-12-01.
+      Backwards compatibility during the warning period is provided by the new
+      content of the `trulens_eval` package which provides aliases to the
+      features in their new locations. See
+      [trulens_eval](trulens/api/trulens_eval/index.md).
+
+    - Deprecated period: 2024-09-01 -- 2025-02-01 . Usage of `trulens_eval` will
+      produce warnings and errors.
+
+    - Removed expected 2024-02-01 Installation of the latest version of
+      `trulens_eval` will be an error itself.
