Yeah, I did the exact same thing; getting it half off in November, & I don't have 0.7a.

I can download 0.7a from the website, but it's not available in from the Install button and even using the Download link from the Library in the Itch App just falls back to 0.5/0.6. This might be because I bought it twice, at different prices, and it's using the initial purchase rather than the latest.
Edit-Actually I just checked the invoice for the latest $10 purchase and it's showing as granting access to the 0.5 files rather than the 0.7 files, so maybe it's just configured wrong ?
