What is Paperless-ngx?

Paperless-ngx shipped its 3.0 rewrite, then spent a week putting out the fires.

3.0.0 landed on July 22 after a long beta, carrying both the largest feature set in the project's history and nine breaking changes. The five releases since are pure repair: a broken migration in 3.0.1 that forced an immediate 3.0.2, then three patch rounds covering OCR skipping, permission-filtered dedup, Gotenberg conversion, email date parsing, AI suggestion caching and search index edge cases. The pace tells you 3.0 shipped into real deployments fast.

What is SiYuan?

SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0

SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.

Paperless-ngx vs SiYuan: editorial side-by-side

P6.3

Paperless-ngx shipped its 3.0 rewrite, then spent a week putting out the fires.

◆ Current state

3.0.0 landed on July 22 after a long beta, carrying both the largest feature set in the project's history and nine breaking changes. The five releases since are pure repair: a broken migration in 3.0.1 that forced an immediate 3.0.2, then three patch rounds covering OCR skipping, permission-filtered dedup, Gotenberg conversion, email date parsing, AI suggestion caching and search index edge cases. The pace tells you 3.0 shipped into real deployments fast.

◆ Where it's heading

The project has moved from a document scanner-and-tagger to a document platform with AI in the core: Paperless AI, remote OCR via Azure, a document parser plugin framework, tantivy replacing Whoosh for search, file versions and sharelink bundles. The breaking changes are the other half of that story — dropping API v1, Python 3.10, document encryption and the old consumer clears the decks for that platform. Recent patches keep touching LLM plumbing, including passing output language into chat and adding docstrings so the classifier reads better as an LLM tool.

◆ Prediction

The 3.0.x patch cadence looks set to run at least another round or two — 3.0.5 is still landing search-compatibility and AI-suggestion fixes rather than tapering. Feature work resuming before that queue empties would be the surprise.

SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0

◆ Current state

SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.

◆ Where it's heading

This is consolidation of the surface 3.8.0 opened, not an extension of it. The agent, semantic search and MCP endpoint arrived in the 3.8.0 line; 3.8.1 makes them portable and pluggable - skills come from a directory the user controls, editor actions follow the user between devices, and the provider layer now speaks the OpenAI Responses API rather than one bespoke shape. The high beta count against a modest final diff shows a project stabilising a young subsystem rather than building a new one.

◆ Prediction

The next line most likely pushes on the skills directory - discovery, sharing or marketplace distribution of user-level skills - since that is the piece 3.8.1 made user-editable without giving it a distribution path.
