When polling a lot of changes it takes very long time for mercurial to generate the changelog. In some cases we care about what was changed but in most of the cases when running test builds for example or when changing branches for testing purposes we do not care about what changes were made.

This will result in much quicker build times.

It will be really nice to have a "Determine changes" checkbox in the plugin settings that will allow to enable/disable the changelog calculation.
