I've noticed a few oddly named Unciv releases like "3.9.20-scenarioTest2"
and "3.10.2-diplomaticRelationshipDisabling". I'm assuming that anything
besides "patch1", etc after the main version number means it's a test
release for an unstable feature or debugging. Thus I am ignoring these
releases. It should be an easy PKGBUILD change if you want to try them.

When I think about it, this package should be called "unciv-bin"
because it's downloading a precompiled binary from the upstream
releases. I'm thinking about resubmitting this package with the
new name and turning the current one into a transitional dummy
package that just depends on the new one. Then I could disown
this package and make it available for anyone who wants to make a
proper "download and compile source" package.

For those who are curious, the "pkgrel" version (e.g., the last "3" in "3.9.0-3") is set to 1 + $PATCH. This scheme will break the package ever needs redoing within a given upstream Unciv release. But it's the cleanest way I could think of to incorporate that information.

I've decided to keep maintaining this package after all, but
would gladly disown it if a more dedicated maintainer wants to
take over. I also posted the PKGBUILD update script to [1].

(License note: The script I pasted into my previous comment is my own work and I hereby license it under the WTFPL version 2.)

I'm moving on from maintaining this package for personal reasons.

For anyone who wishes to adopt this package, here's the script I've been using for automating updates (i.e., change PKGBUILD to point to new version, download it, update sha256sums array, and make unciv-$pkgver-$pkgrel.src.tar.gz for upload). It should be ran from the parent directory of an "unciv" directory that contains the PKGBUILD. I'm sorry for the messy code.

echo "Done! ^.^"

Note: The "Sources" list on this page is inaccurate because I use a "_patch" variable and "${_patch:+-patch$_patch}" Bash syntax in the PKGBUILD to match upstream "-patch1" versions.

I also made a script for automating PKGBUILD updates, but I want to fix some things before posting it (or see if there's a better way than a ton of sed commands to update PKGBUILD versions).…

This package has frequent upstream updates and is relatively low priority for me (updates are unlikely to have particular security implications, and I mostly play Unciv more on my phone). So I triage and this package is often a couple days/weeks out of date. If anyone wants to keep it more up-to-date, then I'll disown it so you can take over. Otherwise, enjoy the game!
