Current version:
https://github.com/Merzasphor/MWSE/releases/tag/v0.9.5-alpha.20150718

New in this version:

• Fixed bug where newly created spells could not be added to an actor. (xCreateSpell)
• Spell names are now properly truncated to 31 characters and don't use more memory than needed (xCreateSpell)
• Spells are created with a default cost of 1. (xCreateSpell)
• xStringMatch no longer finds partial pattern matches.
• Added functions to read and write skill parameters. (xGetSkillInfo, xSetSkillInfo)
• Progress functions no longer need an explicit player reference. They now implicitly access the player's reference as needed. (xGetProgressLevel, xSetProgressLevel, xModProgressLevel, xGetProgressSkill, xSetProgressSkill, xModProgressSkill)

See readme for more information.

From the last thread:


Yes, it's been turned off, and you should no longer experience the bug that qqqbbb, et al., reported.


Yes, you should be able to do some interesting things with these. The big advantage over the progress functions is that these let you dynamically tweak the progress awarded for individual actions, and should help you avoid premature skill ups.
