The MapServer Project Steering Committee (PSC) has voted in January 2021 to rename the default 'master' repository to the less-insensitive name of 'main', for all of the projects under the Github "MapServer organization" umbrella. All repositories were switched to 'main' as the default branch, on 2021-01-15.

Github recently made this renaming more straightforward (https://github.com/github/renaming).

If you have forked one of the MapServer project's repositories, you may receive a notice on your Github project page such as:

Execute the following steps to rename your fork's default branch to 'main':

Step 1: Click on the "Settings" link (top / right of your forked repository page)

Step 2: Click on "Branches" in the left panel

Step 3: In the "Default Branch" section, click on the edit tool (right-side)

Step 4: Type 'main' and click 'Rename branch' button

Locally, execute the following 4 git commands to make sure that your clone's origin will be the new 'main' branch:

  git branch -m master main
  git fetch origin
  git branch -u origin/main main
  git remote set-head origin -a
