Sorry in advance for being blunt, but when it comes to releasing 0.91 you guys really need to shit or get off the pot.
Right now you don't have any viable downloads on your website. The 0.8x series is too resource-intensive for most users, and 0.90 is unusably crash-prone.
A year ago, I could point people in this situation:
http://www.fr33aid.com/1511/fr33-aid-bitcoins-stolen/ at your website and know they'd find something there they could download and use, but that hasn't been true for the last six months and I don't see any particular acknowledgment of this or urgency on your part.
It's not a problem for me personally since I can just grab the 0.91 branch from Git, but a lot of people who can't are losing Bitcoins because there aren't any good usable cold storage solutions any more.
New features are great to have, but they shouldn't delay you having a minimal viable product out, where "minimum viable product" is defined as "an application that lets you send and receive bitcoins from cold storage without consuming obscene amounts of RAM and also doesn't crash every few seconds."
I was not aware that 0.90 was "unusably crash-prone". If that was the case, I would not have delayed the 0.91-beta release. What platforms/contexts are unusably crash-prone (besides Mac)? As far as I can tell, Windows and Ubuntu seem to be working well for most.
