Changes for 0.3.0 release

[mikeskydev]

Tidy up readme, update version numbers

[mikeage]

Looks great! When you merge this, you'll get a 0.2.30 build on main, but after you push the v0.3 tag to main (on the squashed merge commit), it'll build 0.3.0 and create the release in github. (hopefully ;-) )

[mikeskydev]

Thanks for checking, and reminding me which tag I need to make! Will add the GitHub sponsors link and squash.

@mikeage so close! Looks like it didn't pull the full changelog since 0.2?

[mikeage]

Hmmm... did you update the changelog? What's there now looks perfect... I can check the logs from the action

[mikeskydev]

Yes, I've brought in from all the other changelogs manually, it just had the single most recent change before

[mikeage]

Gotcha. It looks like this test wasn't correct:

if [ $(git describe --tags --abbrev=0) == $(git describe --tags) ]
then
    PREV=$(git describe --tags --abbrev=0 HEAD^)
else
    PREV=$(git describe --tags --abbrev=0)
fi

I'll check why in a little bit (going home now). Sorry about that!

[mikeage]

Oh, duh, of course. I copy pasted the wrong thing when I finally merge this. Will fix soon.

[mikeage]

Fixed in #101 (along with a bit of duplicate code removed)
