Just a note for those interested. PCGen had to go through some webserver migration issues but our website is back up and running we are currently on 6.08.00RC6, there have been many sourcebooks added in the last year.
Also we do plan on supporting PF2, but since we aren't a legal entity, and only use the CUP (we've been in touch with Glenn on this). We don't qualify for early access so it won't be ready on day one.
