What is Joplin?

Joplin 3.7 ships AI chat, semantic search, and MCP integration — all off by default, all controllable by the user.

Joplin 3.7 is the product's first real AI release: an in-app chat panel for querying the currently open note, semantic (meaning-based) search across notebooks, and an MCP server that lets external AI assistants connect to Joplin's note graph. The implementation is privacy-first by design — AI is disabled by default, local models (Ollama, LM Studio) are explicitly supported, and cloud AI services only receive the specific note content relevant to a request rather than the full notebook. A companion documentation post published September 14 lays out the privacy model explicitly.

What is Radarr?

Radarr's maintenance run finally carries a few things users will see

6.4.3.10645 is a fuller release than the recent run: Trusted Networks and hostname validation arrive from the shared *arr base, external IDs are included for movies with links and shown only for the main link group, movies can be searched by original title from the page header, and days of the week use translations. The fix list covers Freebox single-file imports, re-importing an already-imported torrent, invalid languages stored in the database or hit during manual import, and connecting to Jellyfin 12 and later.

6.3

Joplin 3.7 ships AI chat, semantic search, and MCP integration — all off by default, all controllable by the user.

◆ Current state

Joplin 3.7 is the product's first real AI release: an in-app chat panel for querying the currently open note, semantic (meaning-based) search across notebooks, and an MCP server that lets external AI assistants connect to Joplin's note graph. The implementation is privacy-first by design — AI is disabled by default, local models (Ollama, LM Studio) are explicitly supported, and cloud AI services only receive the specific note content relevant to a request rather than the full notebook. A companion documentation post published September 14 lays out the privacy model explicitly.

◆ Where it's heading

Joplin is repositioning from a sync-agnostic note-taking app into an AI-native knowledge base, differentiated by opt-in, local-first controls. The HMD Terra M preload partnership and the warrant canary point to a deliberate push toward privacy-conscious enterprise and professional users who distrust cloud-first tools. The MCP integration is particularly strategic: it makes Joplin's note graph accessible to external orchestration pipelines without locking into any particular AI provider.

◆ Prediction

The next major release will likely expand AI chat to multi-note context — currently limited to the open note — and add more configurable MCP tools. The HTR (handwritten text recognition) project from the 2024 French government partnership is also likely to appear in a near-term release.

Radarr's maintenance run finally carries a few things users will see

◆ Current state

6.4.3.10645 is a fuller release than the recent run: Trusted Networks and hostname validation arrive from the shared *arr base, external IDs are included for movies with links and shown only for the main link group, movies can be searched by original title from the page header, and days of the week use translations. The fix list covers Freebox single-file imports, re-importing an already-imported torrent, invalid languages stored in the database or hit during manual import, and connecting to Jellyfin 12 and later.

◆ Where it's heading

Reliability with third-party services remains the axis the work actually moves on — Freebox, Jellyfin, torrent re-import and language handling are all cases of another system behaving in a way Radarr had not accounted for. The framework-level additions in this release are inherited rather than chosen: Trusted Networks, hostname validation and health-check reasons appear identically in Prowlarr on the same day. The genuinely Radarr-specific additions are small search and metadata conveniences, which is the first time in two months the visible surface has moved at all.

◆ Prediction

Expect the external ID and original-title work to continue as metadata breadth rather than becoming a feature cycle, since that is the only axis on which this application has grown recently. The notes give no sign of a larger change.
