v0.11.4, 2026年06月07日 Improved error reporting / Added nbexec flags

• nbexec: Added -export_html flag to export the executed notebook to HTML at a specified target path.
• nbexec: Added -check_cells flag to check and report cells that failed execution, exiting with code 1 if any failure occurs.
• Fixed an issue where the Cell/Line or errors were not being displayed correctly.
• Extended cell compilation error hover popups to also trigger when hovering over the cell/line area, in addition to the file/line area.
• Added support for rich HTML execution/runtime error reporting, enabling hoverable popups that show code context directly over Go stack traces printed to stderr (e.g. panics and fatal logs).
• Refactored execution error handling: stderr streams in real-time to Jupyter (not buffered), and the rich hover-popup HTML boxes for cell-related error lines are printed after the execution exits.
• Improved error CSS layout to wrap long code lines without displaying horizontal scrollbars.

• Added -go_work flag that also works with the installer gonb -install.
• Added a %%gx cell magic that will eventually support gx cells. Currently just echoes the cell code and allows executing go code below. Requires --tags=gx.
• Bumped Go to version 1.24.4 in preparation for using GX.

• Support Jupyter for more OSSes (thanks @yuce!)
• Updated dependencies
• Increased gopls timeout.
• Package plotly:
  • Added DisplayFigAsJSON and AppendFigAsJSON to display Plotly figures directly from their
    JSON rendering. This allows one to do arbitrary editions.
• Installation:
  • Fixed the handling of the installation flags forwarded to the kernel execution.
  • Make a copy of the binary if the gonb binary is under a .cache directory. Same as is already done if
    the binary is in a temporary directory.
  • Fixed duplicate error logging issues.
• Added internal util package. Improved error logging.

Very small update, but bumped the version number because the plotly package API is broken, due to the dependency on the new go-plotly version. A trivial update, if you have problems, just update your go-plotly dependency as well.

It also adds the plotly.DarkTheme, plotly.Seaborn and GGPlot2Theme that can be used in your Plotly figures (based on plotly.io Python package).

• Updated dependencies:
  • Bumped go-plotly dependency to v0.7.0.

• New --version and -V flags to print version; Improved %version output. (#158)
• Clean up, refactorings and fixed context leakage.
• Added version.txt with target version for build.

• Reverted replace directive: contrary to what the AI suggested, it doesn't work when running from outside a cloned repository.
  • Temporary solution, as this leaves gonb "at the mercy" of the default GOPROXY proxy.golang.org continuously proxying
    the now extinct packages under go.lsp.dev. See #157
  • See more in: go-language-server/jsonrpc2#28
  • v0.10.9 skipped: issues with the release and GOPROXY. Instead I skipped the version.

• Added a replace directive from go.lsp.dev/{jsonrpc2,uri,protocol} to github.com/go-language-server/{jsonrpc2,uri,protocol}
  in go.mod, since go.lsp.dev seems to be down.
• Updated dependencies to go.lsp.dev/uri and go.lsp.dev/protocol.
• Set MIMEType KernelLanguageInfo.MIMEType, which enabled auto-complete with VSCode+Polyglot to work with GoNB+Auto-complete.
  Thanks @tonidy for the find and fix. More in dotnet/interactive#3511
• Updated Dockerfile to build the docker from main/HEAD.

• Improved autostart logic: it now requires being mounted as "readonly" under /root/autostart.
• Added %version, and environment variables GONB_VERSION, GONB_GIT_COMMIT.
• Added %help info on missing environment variables.
• Added stack traces to protocol parsing errors.
• Include function comments in the generated code. This makes tags like //go:noinline work. See #150
