Short answer: No, the repo has not been abandoned.
langchain-community is still actively maintained. Even if the visible commit frequency looks low at times, maintenance activity doesn’t always show up as steady daily commits — reviews, internal syncs, refactors in related repos, and batching of merges can make it look slower than it is.
A few important points:
The repo still receives commits (including very recent ones).
PR backlogs can fluctuate depending on:
Maintainer bandwidth
Priority work in core repos
Ongoing refactors across the LangChain ecosystem
Large ecosystems often go through cycles — periods of rapid merges followed by stabilization/cleanup phases.
The 147 open PRs doesn’t necessarily mean stagnation — many may:
Need changes
Be waiting on contributor updates
Be blocked by dependency refactors
Overlap with other work
If your PR hasn’t been assigned after a week, that’s not unusual for high-traffic OSS repos. A polite follow-up comment (once) is totally reasonable.
So in short:
It’s still maintained — just operating at ecosystem scale, which can feel slower than earlier phases.
