Hi, I actually did a bit of the math. So currently, 0.5 came out less than three months ago for tier 2+ patrons. 6 days later, it released for tier 1 patrons and 0.4.8 was released on Itch to the public. That's how CHYSA does things, so when 0.5.5 gets released for tier 2+ patrons, about 6 days later 0.5 will be on Itch. CHYSA has a progress page on patreon in the "About" section, and judging by their own calculations, they're over 2/3 of the way through 0.5.5. Maybe about a month, at least, if I had to guess.
