Deepgram is widening language coverage while quietly replacing its diarization core.
Deepgram shipped a new batch speaker diarization architecture as an opt-in diarize_model parameter, then made it the default in the May self-hosted release. Alongside it, profanity filtering rolled out to 50+ monolingual languages and then to all multilingual models, numerals support reached Russian, Romanian, and Hebrew, and Gemini 3.1 Flash Lite replaced its preview version in the Voice Agent API.
Misskey's next release cuts server memory by up to 140MB with a new start script.
Misskey, the ActivityPub social server, follows a monthly alpha-to-release cycle. The 2026.11.0 alpha adds a production start script, node ./scripts/start.mjs, that avoids leftover resident processes and cuts memory use by 70 to 140MB; official Docker images use it automatically. It also carries the improved display of quote posts from Mastodon and other software, plus a batch of deck, chat and push-notification fixes. October's 2026.10.1 moved to Sentry SDK v11.

Two tracks run at once. The model track is a genuine architecture replacement in diarization, moved from opt-in to default inside a week and a half, which is a fast promotion for a core speech component. The coverage track is unglamorous breadth — languages, filters, numerals — that determines whether the platform can be adopted outside English-first markets. The Voice Agent work is managed-model plumbing rather than a direction of its own.
Diarization v2 should reach streaming after landing in batch and self-hosted, since that is where the earlier architecture is weakest for live agents. Expect the language-coverage releases to continue at the same steady cadence.

Recent releases lean on operator concerns: security fixes, Sentry configuration, safe startup on bad queue config, and now memory footprint. Federation polish with non-Misskey software continues alongside, which matters for smaller self-hosted instances.
2026.11.0 is likely to go final within weeks carrying the start script, following the pattern of alphas reaching release in two to three weeks. Further memory or query-reduction work looks likely given the server fixes trimming unneeded user-data lookups.
