I finished a run in Giftscop 1.2-pre27 and came to upload it here but there is no category for 1.2. Will there be a new category made ever or what?

Probably not until the final 1.2 build is released, if you can, try doing the run in 1.1.1 for now

Now that 1.2 is out of prerelease, we are updating things so 1.2 runs can be submitted.
