What is AFFiNE?
AFFiNE's canaries stay on upkeep: a Swift Collections bump follows CVE and migration fixes.
AFFiNE ships a canary build almost daily, and nearly all of October has been dependency and infrastructure work. The newest, canary 915, bumps Apple's Swift Collections package to 1.7.4 for the native apps. Before it came a happy-dom code-execution CVE patch, payment-record repairs during a data migration, and non-root, read-only containers with multi-architecture Windows builds.
What is Outline?
Outline adds personal docs even admins can't open, pairing agent access with user privacy.
Outline ships on two tracks: an agent integration surface (April's MCP editing tools, September's browser-native WebMCP) and steady workspace UX work. The October release gives every member a Personal sidebar section for drafts and notes that no one else can see, admins included. That is a notable stance for a team wiki, where admin visibility is usually the default.

AFFiNE
5.0COLLAB
AFFiNE's canaries stay on upkeep: a Swift Collections bump follows CVE and migration fixes.
◆ Current state
AFFiNE ships a canary build almost daily, and nearly all of October has been dependency and infrastructure work. The newest, canary 915, bumps Apple's Swift Collections package to 1.7.4 for the native apps. Before it came a happy-dom code-execution CVE patch, payment-record repairs during a data migration, and non-root, read-only containers with multi-architecture Windows builds.
◆ Where it's heading
The feed reads like a team hardening the backend and toolchain ahead of a larger cutover: a payment-identity migration, stricter deployment defaults and steady Renovate bumps across web, server and native code. Feature work isn't visible in canaries this month; the last user-facing fix was October 12's blob-upload quota correction.
◆ Prediction
Expect the data migration to finish in the next canaries, followed by a stable release that bundles it; the entries don't show which user-facing feature is next.
Outline
2.5COLLAB
Outline adds personal docs even admins can't open, pairing agent access with user privacy.
◆ Current state
Outline ships on two tracks: an agent integration surface (April's MCP editing tools, September's browser-native WebMCP) and steady workspace UX work. The October release gives every member a Personal sidebar section for drafts and notes that no one else can see, admins included. That is a notable stance for a team wiki, where admin visibility is usually the default.
◆ Where it's heading
Outline is building toward an agent-accessible knowledge base that individuals also use for private work, not only shared documentation. MCP and WebMCP opened the content to agents, Open Knowledge Format export lowered lock-in, and personal documents pull pre-publication drafting into the product. The pattern is to widen what lives in Outline while giving users clear control over who, or what, can reach it.
◆ Prediction
The next likely move is connecting personal documents to the existing flows, for example promoting a personal draft into a shared collection or defining what the MCP tools can see in personal space. The entries don't show how agent access and personal privacy will interact, and that is the open question.
