Version 0.1.6

This release improves the handling and visibility of tags across all node types, ensuring consistent rendering and better user experience. It also includes detailed documentation to help future contributors understand the node tags architecture.

New Features

  • Documented the node tags architecture with guidance on rendering, CSS considerations, and adding new node types (b6fc56) (Eric Ma)
  • Refactored tags to be a fundamental property of all nodes by rendering them centrally in renderNode(), preventing accidental omission in new node types (81b0e3) (Eric Ma)

Bug Fixes

  • Fixed tag visibility issues by removing overflow:hidden from node containers, allowing tags positioned outside node boundaries to be fully visible (2916df) (Eric Ma)
  • Ensured tags remain visible at all zoom levels and added missing tag rendering for Matrix nodes (ecdd52) (Eric Ma)

Version 0.1.5

This release introduces URL fetching support to the /note command, allowing users to include content from web pages as markdown. It also improves development workflow by adding a pre-commit hook to keep the pixi.lock file in sync with pyproject.toml changes, ensuring dependency consistency.

New Features

  • Added URL fetching capability to the /note command, including a new API endpoint that converts web pages to markdown using Jina Reader and html2text as a fallback. Also included documentation and tests for this feature (e0117d) (Eric Ma)
  • Added a local pre-commit hook that automatically updates the pixi.lock file when pyproject.toml changes, preventing the lockfile from becoming stale (976c60) (Eric Ma)

Bug Fixes

  • Synchronized pixi.lock file after version bump in the automated release workflow to maintain consistency (58bb2c) (Eric Ma)

Version 0.1.4

This version improves the user experience of the layout view by maintaining the current viewport, adding helpful hints, and enabling easier navigation when zoomed out.

New Features

  • The layout view no longer auto-zooms to fit content, preserving the current viewport for better user control (7e2e87) (Eric Ma)
  • A hint overlay is shown when nodes exist but none are visible in the viewport, helping users understand the layout state (7e2e87) (Eric Ma)
  • Users can drag nodes from anywhere when zoomed out (scale ≤ 0.6), improving navigation and interaction (7e2e87) (Eric Ma)
  • Added a codebase map to AGENTS.md to facilitate easier navigation of the project (7e2e87) (Eric Ma)

Version 0.1.3

This release introduces a new slash command to create standalone markdown notes, allowing users to paste content such as papers or notes without triggering an AI response. These notes can be edited and used as context for branching questions.

New Features

  • Added the /note command to create standalone NOTE nodes for markdown content, which do not auto-attach to existing nodes and have a 4:3 aspect ratio with scrollable content. An edit button is also enabled for modifying note content (41d3e8) (Eric Ma)

Version 0.1.2

This release introduces a powerful new feature called the LLM Committee, enabling multi-model consultation with parallel querying, peer review, and synthesized responses. It also includes retroactive release notes for previous versions and improvements to the release note generation process.

New Features

  • Implemented the LLM Committee feature that allows querying multiple language models simultaneously, includes a peer review stage where models critique each other, and synthesizes the final response via a chairman model. This includes backend SSE endpoint, frontend modal for model selection, and streaming UI with stop controls. (f46fdf) (Eric Ma)
  • Added retroactive release notes for versions 0.1.0 and 0.1.1 to improve documentation and changelog completeness. (38bb01) (Eric Ma)
  • Integrated LLM-generated release notes using llamabot in the auto-release workflow, automating the generation and storage of release notes for future versions. (357656) (Eric Ma)

Version 0.1.1

This release brings major improvements to the Canvas Chat experience, including a robust CI/CD pipeline, automatic PyPI publishing, a refactored Python package structure, and significant enhancements to the force-directed layout and node overlap handling. It also introduces LLM-generated release notes, improved test coverage, and a more reliable and maintainable codebase.

New Features

  • Add LLM-generated release notes using llamabot, with automated storage and GitHub release integration. (116346, Eric Ma)

  • Refactor to a proper Python package structure for PyPI publishing, including CLI entry point and improved test imports. (f836a6, Eric Ma)

Bug Fixes

  • Fix force-directed layout edge spring to respect node sizes, preventing large nodes from overlapping when connected by edges. (7ff72f, Eric Ma)
  • Fix force-directed layout overlap detection for rectangles, ensuring repulsion only when bounding boxes actually intersect. (7c2ca1, Eric Ma)
  • Fix resolveOverlaps to properly separate large nodes, improving convergence speed and correctness for heavily overlapping nodes. (53686c, Eric Ma)
  • Fix handleNodeResummarize to use correct streaming pattern, and document API verification steps for agents. (3367d9, Eric Ma)
