v0.11.0

Fixed

• Playgrounds now ensure that the service worker they are connected to have a
  matching version. Fixes issues relating to playgrounds being broken for some
  time after an upgrade.

• The --playground-tab-bar-font-size CSS custom property now behaves as
  documented, and defaults to 14px.

• The --playground-floating-controls-color CSS custom property now behaves as
  documented.

• Fix missing .js extension from import in build.js that may have broken
  Webpack and other builds.

• The hover effect and touch area for tabs in the tab bar are no longer offset
  by the height of the active tab indicator.

• Fix bug that caused failures to load d.ts files and "Could not resolve
  module specifier" console errors when using import maps.

Changed

• BREAKING playground-base-url is now resolved relative to the
  import.meta.url of the module containing the definition of
  <playground-project>, instead of relative to document.location.href as
  before. This means that . can now be used to refer to the local playground
  installation directory.

• The service worker now sets the Origin-Agent-Cluster: ?1 heading on all
  responses, to encourage browsers to allocate a separate process or thread for
  Playground preview iframe under certain conditions. See the Process
  isolation
  section of the README for more details.

• It is now possible to change the font-family of the tab-bar using a
  ::part(tab-bar) selector.
