xxx Molly is behind a few versions too now.
Was it? I was on v7.53.5-1 from Accrescent (August 26), the only versions since then were a pre-release from October 16 which I don't know if those get pushed to Accrescent, and the current latest which came out 3 days before Accrescent was fixed. So it didn't hold that one back too much (unless some very serious security fixes were in 7.61.3)
I'd recommend subscribing to the Github to get email notifications when new releases are added, and you can check if Accrescent has kept up. The built-in update check for Molly from the Github releases is not necessarily reliable either though; it has failed in the past and left me >10 versions behind, to a point where the version I had installed wasn't working anymore, and I hadn't noticed because I rarely use it in the first place. So this with Accrescent could have been pretty bad, had there been more (mandatory) updates to Signal between August 26 and now.
