• Upgrade of Elixir Programming Language Version
  The software language, Elixir, we use in our application has been updated to its newer version, 1.17.2. This ensures we're utilising the most recent features, improvements, and security updates released by the Elixir community.

• Updated Compatibility Measures
  To ensure this new version of Elixir works flawlessly with our application, unique identifiers - 'rev' and 'sha256' - have been updated. This essentially acts as the bridge, making the new Elixir version compatible with our existing setup.
