Fox Thigh Highs

• Changed versioning from semver to git hashes.
• Changed pack_format from 23 to 26.
  • the Fandom Wiki claims 23 for 1.20.3-1.20.4, but minecraft.wiki claims 26. The fandom wiki has moved to https://minecraft.wiki, so we're going with that.

Going forward releases will only contain the changed files, not all files.
