• Return adjusted stop from bin transform (thanks @domoritz!) (via #3967)
• Parse SVG paths containing a z (closepath) without a following space separator (thanks @hydrosquall!) (via #4236)

Maintenance

• Migrate vega-util to TypeScript (thanks @hydrosquall!) (via #4185, #4187, #4188, #4189, #4200, #4202, #4203, #4218, #4219, #4220, #4222)

• Add package metadata for homepage and issues (via #4282)
• Update node and TypeScript configuration at the repo root (via #4184)
• Numerous dependency bumps via dependabot (lerna 9, rollup, babel, jsdom, canvas, d3-format, GitHub Actions, and more)
• Docs: use the main data set for the domain in the grouped bar chart example (thanks @sl-solution!) (via #3593); zoomable scatter plot example cleanup (via #4217); grammar and typo fixes (via #4157, #4172, #4175, #4199)

Package versions

Unchanged (nothing new since their last publish): vega-canvas 2.0.0, vega-event-selector 4.0.0, vega-statistics 2.0.0, vega-util 2.1.1. Unlike v6.2.0's two-step release (#4132), vega-cli ships in this release: it pins vega to an exact version, so leaving it at 6.2.0 while the workspace moves to 6.3.0 makes npm install a nested registry copy of vega instead of linking the workspace package, which breaks the build ordering and CI.
