Below we cover the 3 phases of lesson transition towards the Carpentries Workbench:

- transition-step-1 (`transition_url` variable needed): we indicate that there

is a new version of the lesson that is available for testing, and that it will be deprecated in the future.

- transition-step-2 (`transition_url` and `transition_date` variables needed): we indicate that a new version of the lesson is avaiable with a deprecation date.

- transition-step-3 (`transition_url` variable needed): the lesson is fully deprecated, and a redirect is set up to the new URL

Below we cover the 2 phases of lesson transition towards the Carpentries Workbench:

Variables needed:

  - transition_date_prebeta: the date of the prebeta stage

  - transition_date_beta: the date of the beta stage

  - transition_date_prerelease: the date of the prerelease stage

- transition-step-1: We notify that there is a snapshot of the lesson available for testing, and that it will supersede this version.

- transition-step-2 We indicate that this version of the lesson is a snapshot and a new version of the lesson is avaiable and will supersede this version at a given date.
