Security

• Vim plugin: Version 0.2.0 executed node_modules/.bin/quick-lint-js without
  validating that the program is really quick-lint-js. The plugin now
  conservatively ignores quick-lint-js in node_modules by default.

Added

• New JS syntax: .?, class fields, import.meta, top-level await,
  #privateProperties
• Translations: Swedish (implemented by Kim "Linden")
• Emacs plugin (implemented by wagner riffel)
• Neovim plugin
• Errors and warnings are now documented on the website
• Various new errors and error message improvements (implemented by
  AidenThing, Daniel La Rocque, Erlliam Mejia, Himanshu, Lee
  Wannacott, [Matheus Sousa][])
• Shell completion for the CLI (Bash, Fish, Zsh) (implemented by Shivam
  Mehta)
• --stdin CLI option allows reading JavaScript from standard input instead of
  a file (implemented by wagner riffel)
• Partially implemented: Global variables can be configured using a
  quick-lint-js.config file

Fixed

• Using browser variables such as document and window no longer reports
  undesired undeclared variable warnings
• with statements and eval no longer cause spurious undeclared variable
  warnings (implemented by Himanshu)
• ++a[0]; no longer reports an assignment-to-const-variable error if a was
  declared with const (implemented by Himanshu)
• 'undefined' === typeof foo ? 3 : 4 no longer reports a warning that foo is
  undeclared (implemented by Himanshu)
• Building tests with GCC 11.1.1 no longer fails due to -Werror
• Various crashes given invalid JavaScript no longer happen
• Building the VS Code plugin now works on Windows (implemented by Jimmy
  Qiu)
