FlavoredScrabble In addition to what was said in by @matchboxbananasynergy in matchboxbananasynergy, the repository you're referencing is only one of about 10 actively maintained repositories under the Accrescent project, of which a few are currently private. Most active development over the past many months has occurred in these private repositories, so the changes aren't yet visible. The plan is to publish them once the components they contain are ready for deployment.
The project isn't dying and is still actively maintained. However, as already stated, I'm only able to work on Accrescent in my free time, so that's why development isn't as active as would be preferable.
