Hi,
Is this build - https://www.curseforge.com/minecraft/mc-mods/torchmaster/files/3017979 actually version 1.8.2?

No, this is 1.8.1.82. There is no version 1.8.2.
1.12 uses the scheme MAJOR.MINOR.PATCH.BUILDNUMBER
With MC 1.13 i removed the buildnumber from from the version string as it didn't provide any additional information. Every release I do will always increase either of the 3 version numbers, so there is no point in having the buildnumber.

Whoops, well - yes, it looks like this should've been 1.8.2.82. The version 1.12 actually builds automatically and I always forget to update the version number. I guess I changed the version number and did the commit but selected the wrong file to release. The Dreadlamp Visual Bugfix should still be in this version though.

No worries, I wondered because the file in CurseForge also didn't have the proper changelog.
I've marked the update in my Technic Solder as 1.8.2 (I also marked the previous ones without the buildnumber as I saw it was pointless)
