I don't know when that would be mate.
2.54 is close to Beta, but I need to finish implementing all of the datatypes and some less dramatic stuff. It sucks, as I lost the combodata vars in my HDD crash. I thought that I had committed it to the repo, but apparently I did not, so I have the added bonus if doing that again. It's a mere 83 instructions .
...plus some new stuff that I was prepared to append to it. Ugh.
Alpha 21 will be close to what I envision as 'Beta 0'.
