 All changes to the package starting with v0.3.1 will be logged here.
 
+## v1.2.0 [2023-03-03]
+#### What's New
+* Support for Azure Managed Identities as federation providers.
+
+#### Enhancements
+* Fall back to reduced functionality (no shell completion) when the python environment is using `click<8.0.0`.
+
+#### Bug Fixes
+* If a justification for checkout/secrets viewing is provided, ensure it is <=255 characters.
+* Fix issue with extraction of OIDC token expiration time. Moved to `jwt` library to perform the token decode.
+
+#### Dependencies
+* Switching `britive` dependency from a compatible version requirement to a `>=` requirement to capture minor updates.
+* `britive>=2.16.0` from britive~=2.15.1
+
+#### Other
+* Modify the error handling and reporting process to not raise `click.ClickException` exceptions in the `safe_cli` method. Instead, raise the underlying exception so a better error message is provided.
+
 ## v1.1.1 [2023-02-16]
 #### What's New
 * None

 The end user is free to install the CLI into a virtual environment or in the global scope, so it is available
 everywhere.
 
+If the `pybritive` executable is not found when attempting to invoke the program, you may need to add the location
+of the `pybritive` executable to your path. This location can differ by OS and whether you are using a virtualenv or
+not. The easiest way to see where executables get installed via `pip install ...` is to run the following command.
+
+~~~
+echo `python3 -m site --user-base`/bin

+You will need to add this location to your path. The following command will do that but it is recommended to add
+this command into your `.bashrc, .zshrc, etc.` file, so it will always get executed on new terminal windows.

 Before `pybritive` can connect to a Britive tenant, it needs to know some details about that tenant.

 However, if you are using one of the above providers, a shortcut is provided to abstract away the complexity of sourcing these tokens.
