Yes I know that my aggregation is not the universal truth.

I tried to aggregate the interesting informations from the SVN log,
devided it into three sub-sections and filtered out lots of
uninteresting stuff like "fixed a typo, renamed a file, added this
unimportant line of code" and so on...

You are right, I only looked at the trunk. So only development versions
are included here. Sorry for that.

Again, I know it's not the best way of doing it, but I wanted to create
at least an overview that most people can understand.

The real main problem is the fact that the informations in the SVN
changelog mostly are held too short and does not give you an information
about the importance of a change.

It is the responsebility of every developer with write access to the SVN
to add an informative log describing the problem and the solution to
each svn checking and also to give a hint about the importance of the

Then we could keep this list much shorter and more informative to the

My first intention was something like the kernel changelog:


Which is much more informative than our SVN changelog but still totally unreadable.

Ideally something like 


How can we achieve that every developer will cultivate it like this?

How to make the right trade-off of the importance (So we should not list everything but what is important enough?)

Any comments are wellcome :)
