+We want the 0 series to be backward-compatible. That means that a project created with MapMap 0.1 should still work with MapMap 0.99, if we ever get to such a version number. When we will break this backward-compatibilty, we will start the 1 series and provide a migration script. This script might be ran from the command-line or on the Web. The other thing we need to be backward-compatible is the OSC interface. The rest of the software can change. This includes the names of the menu items and the appearance of the user interface. We will try to keep these consistent, though.

+Code management with Git
+------------------------
+* We develop in the develop branch. The master branch is only for the latest tag.
+* Create a branch for each new features. Merge it to develop.
+* Create release-x.y.z branch for releases.
+* If possible, avoid merges, and use git rebase instead. (like in the GNOME projects)
+* Create a x.y branch for each x.y major.minor version series.
+* For a new release, merge develop to master (or your branch to the major.minor branch if it's a bugfix release) and then tag it there.
+* In doubt, ask the release manager.
+
+Make a release
+--------------
+* If it's a new feature, increment minor. If it's bugfix, increment micro. If it's not backward-compatible, increment major.
+* Create a release-x.y.z branch
+* Verify the version number:
+  * VERSION in mapmap.pro
+  * PROJECT_NUMBER in Doxyfile
+  * MAPMAP_VERSION in MainWindow.h
+  * MAPMAP_VERSION in sh_make_tarball.sh (until we fixe the tarball target in .pro)
+* Edit NEWS
+* run make
+* run ./sh_build_doc.sh
+* merge to master, or to the major.minor branch
+* run ./sh_make_tarball.sh
+* then untar it, cd to that dir and build the whole thing to see if it works
+* git tag x.y.z
+* go back to your release branch
+* increment micro (or minor) version number in the files above.
+* merge into develop.
+* keep developing.
+
+XML file version number
+-----------------------
+* update its minor number when you introduce new features.
+* update its major number when it's not backward-comptatible anymore with its previous versions
+* generally, we should follow the MapMap version, when new changes are introduced. (no need to increment it otherwise)
+* we will need to implement some fancy XML file version number checking in the future.

+* be able to change the media source
+* is it really the closest vertex that is dragged?
+* how come paint quads don't have a dimension?
+* create more number boxes for points when we change the dimension of a quad texture mapping.
+* Be able to cancel a change when moving around a mapping.
+* Be able to change the color of a color paint.
+* Be able to undo deleting a mapping, and a paint.
