v0.4.0

Breaking changes

• Require Volt 0.19. Lint :plugins, :env, and :globals in config :volt, :lint take string names, such as plugins: ["typescript", "jsx-a11y"]; see Volt's changelog.
• Require MDEx 0.14.1 and Lumis 0.10 for syntax highlighting. Lumis 0.10 installs each language's parser as its own lumis_wasm_* package; add one for every language your code fences use.

Fixed

• Show development render errors in Volt's error overlay instead of crashing the request with an empty 500. Exceptions raised while rendering .astral pages, layouts, and components are reported with Volt.HMR.error/3 with their source file, line, frame, and stacktrace, and the overlay clears once the page renders again. The error page keeps the error as plain text for clients without JavaScript.
• Report the component's own .astral file in stacktraces instead of the page or layout that rendered it.
