And then after 5.1, basically every minor version (5.2, 5.3, so on) have major changes between them, from what I recall.

Their defence is always that they do not follow semver.

I remember some undocumented edge cases in string match patterns breaking between 5.1 and 5.2. Imagine Python changing how regexes worked between two minor releases.

"Defence"? Seems like the correct answer and a fact, Lua doesn't do semver, so when there are major changes between 5.3 and 5.4, it's not illogical or actually breaking semver, as they don't follow it.

Plenty of projects don't follow semver, and that's perfectly fine.
