What is Misskey?

Misskey deleted its bundled machine-learning stack and made moderation someone else's service to run.

The visible history is essentially one release train, nine tags from 2026.7.0-beta.0 through the 2026.7.0 release, plus the first alpha of 2026.8.0. The defining change is that sensitive-media detection no longer runs inside Misskey: nsfwjs, TensorFlow.js, and the bundled NSFW model are gone from the codebase, replaced by HTTP calls to a separate sensitive-detector service. Operators who rely on the feature must stand that service up and point the control panel at it; if they do not, detection stops and all media is treated as non-sensitive.

What is Respond.io?

respond.io is widening the inbox again after landing Copilot and metered AI credits.

Early August was respond.io's AI moment: Copilot arrived in every workspace with an agent builder that drafts and test-runs an AI agent, and AI Credit On-Demand started billing overage instead of cutting AI off at the plan limit. Since then the work has moved back to the inbox itself - a Microsoft 365 and Outlook email channel, TikTok Business Messaging for US-registered accounts, conversation collaborators who can act without reassignment, a missed-call follow-up template, and now a contact's Google Calendar meetings shown beside the conversation.

Misskey deleted its bundled machine-learning stack and made moderation someone else's service to run.

◆ Current state

The visible history is essentially one release train, nine tags from 2026.7.0-beta.0 through the 2026.7.0 release, plus the first alpha of 2026.8.0. The defining change is that sensitive-media detection no longer runs inside Misskey: nsfwjs, TensorFlow.js, and the bundled NSFW model are gone from the codebase, replaced by HTTP calls to a separate sensitive-detector service. Operators who rely on the feature must stand that service up and point the control panel at it; if they do not, detection stops and all media is treated as non-sensitive.

◆ Where it's heading

The direction is a smaller, more conventional Node application with its heavy and specialized dependencies pushed outside the process. The same release raises the Node floor to 22.22.2, 24.17.0 and 26.4.0, moves the Docker image to Node 26 on Debian trixie, and inherits a sharp requirement that breaks x86_64 CPUs without SSE4.2. The rebuilt logging layer points the same way, with one-line JSON output, per-domain levels, automatic credential redaction, and Sentry trace correlation, which is what an operator using standard tooling wants rather than what a self-contained appliance would ship.

◆ Prediction

Node 22 support is already flagged for removal, so the next train should drop it. Whether OpenTelemetry returns after being pulled between beta.6 and the release candidate is not something these entries settle.

respond.io is widening the inbox again after landing Copilot and metered AI credits.

◆ Current state

Early August was respond.io's AI moment: Copilot arrived in every workspace with an agent builder that drafts and test-runs an AI agent, and AI Credit On-Demand started billing overage instead of cutting AI off at the plan limit. Since then the work has moved back to the inbox itself - a Microsoft 365 and Outlook email channel, TikTok Business Messaging for US-registered accounts, conversation collaborators who can act without reassignment, a missed-call follow-up template, and now a contact's Google Calendar meetings shown beside the conversation.

◆ Where it's heading

The pattern is accumulation around a single conversation view rather than depth in any one channel. Each release adds either a place messages arrive from or a piece of context that used to require another tab, and most ship as pre-built workflow templates or read-only panels rather than as new configuration for an admin to learn. With AI usage now metered rather than capped, every surface feeding the inbox is also more material for agents billed against those credits - the channel expansion and the AI pricing change point the same way.

◆ Prediction

The calendar integration is read-only and sends users to Google to create or edit, which is the obvious next gap to close. Beyond that, expect channel availability to keep opening region by region on the TikTok pattern rather than new channel types arriving.
