v2.2.2 (2026-07-26)

New features

• Define Dygraph.integerTicks (#925), Dygraph.pickDateTickGranularity
• Warn in console if points are out of range (#1050)

Bugfixes

• Re-add missing Dygraph.DOTTED_LINE export
• Some edge cases in the crosshair plugin (#1034, #1038, #1039, #1040)
• Update list of exported symbols
• Drop “comments are OK on data lines” from the CSV documentation, as the CSV file format has no notion of a comment, and the current code merely strips lines beginning with an octothorpe and reportedly sometimes also parts of fields, but (obviously) the field separator can then not be used within a comment
• Document that the input data should be sorted (#503)
• Make date parsing more robust and in particular, allow the epoch (#1062)
• Work around breaking changes in newer node-source-map (Debian#1134275)

Other user-visible changes

• Add talk link to tutorial.html
• Documentation: make clear that use of so-called “AI” / LLMs to prepare a contribution or to communicate with the project or its users is not permitted
• Fix most broken links

Internal refactors/fixes

• Switch from jsdoc-toolkit to node-jsdoc2 (Debian #1074595)
• Bump some package versions matching Debian bookworm and *buntu 24.04
• Add support for newer babeljs and uglifyjs3
• Do not embed pre-uglified browser-pack shim, as it may break old browsers
