Larian Studios Forums Divine Divinity (English) General Patch Confusion

I remember seeing the "remastered" version of the game advertised as 1.4a and (I think) 1.05/1.05a.

Are there any differences here?

Edit: Wow...another topic with the exact same name...it doesn't EXACTLY cover my question, though.

The original remastered version was 1.004A, which people often abbreviate to 1.04 or 1.4. The patched download version (which should already be integrated into the download files at GoG and Impulse) brought the version number up to 1.005A (AKA 1.05 or 1.5).
