Git branch conventions

We follow the Git Flow branching model (Read more about it in the original document describing it). Basically that boils down to having at least two branches:

  • develop - for the daily work, always has the latest merged commits, and is equal to or ahead of the latest release
  • master - only changes on new releases (right now and until the 3.0.1 release, some of our repositories don’t have a master branch but will get one then again)

Furthermore there might be more branches, which must always be namespaced:

  • feature/<name> - Used for developing new features (feature/printservice)
  • hotfix/<name> - Used for making hot fixes for releases (hotfix/bug_123)
  • release/<name> - Used for preparing releases, very short-lived (release/3.0.1)

Some Linux distributions have a package called git-flow which will provide easy git command shortcuts to use the merge/branch model of Git Flow without having to do everything by yourself (which is still possible and you should always know how Git Flow uses plain git to achieve things).

  • naming conventions

Issue conventions

Issues (bugs and features) are administrated in the mapbender-repository at:

We create a milestone for every version of Mapbender3:

There are some rules you should keep in mind:

  • write understandable tickets!!
  • write your title so that the issue is already described in the title:
  • write comments with all necessary information: * for bugs: describe step by step how the error can be reproduced * for features: describe feature and functionality
  • when you create a new ticket do not assign it to a milestone or developer, if you are not sure
  • add labels to your ticket * bug - describes a bug that orrurs in a special version of Mapbender3 (add info about the version) * feature - new feature * enhancement - stands for feature enhancement * wip - work in progress
  • when you work on a ticket or close it please assign a user and milestone
  • when you close a ticket, please:
    • add a comment in the ticket and refer to the commit,
    • refer to the documentation at or a demo if possibile.

Version conventions

The Mapbender3 version is defined by a four digit numbering system, seperated by dots.

  • The first digit is constant and represents the Mapbender3 software cycle.
  • The second digit describes all new features and major changes in Mapbender3, with the highest difficulty level of a update process.
  • The third digit describes new features and minor changes, which can be easily updated.
  • The fourth digit represents only bugfixes and micro changes.

Increase a digit means always a reset for all digits before. For example - ->
