This is the claim used to make edits and fixes to TR_Mainland. Do not make changes arbitarily.
TR_Mainland should not break compatibility unless it is structurally necessary. This means do not change the IDs of anything that was released in a TR_Mainland.esm unless strictly necessary.
TR_Mainland is the esm which contains the “finished” parts of Tamriel Rebuilt. Save major restructuring, the landmass contained within is supposed to be fully interiorised, npced, quested, and cleaned.

Uploaded here is only the esp. Make sure to redate the .esp to 01/01/2012 18:00:00 with WryeMash so that it loads before other plugins that rely on it. Remember to load this when doing edits to the section files.
Quests and dialogue refinement. Veloth's Path could be widened if desired, and its texture changed to the one used west of Alt Orethan.
Gnomey can be asked for details, if an implementation is desired and looking at those areas don't make clear what is required.
Various works of touching up existing content, such as reworking that AI island in Boethiah's Spine, giving the IAS members their faction assignment, and the like, should be kept an eye on.
Additionally, medium-term, the cliffs should be replaced with our newer meshes.
