Roadmap

Q1 2015: jQuery 3.0 and jQuery Compat 3.0

See issue tracker for 3.0.0 tickets.

Ongoing work

• Potential use of new DOM/ES features , if they improve performance (e.g., gh-1868 and gh-1753)

  • Historically, new DOM/ES features have not been performant so we'll need to jsperf them and weight against increased code size and complexity.
  • May need new API surface for things like .usedStyle and it may be master-only

• Improve modularity (e.g., gh-1864)

  • This may only be possible/useful in the master branch, since -compat uses so much of the plumbing to backfill IE8 shortcomings.

• Start using ES6 modules and transpile to other formats.

  • PEP has already started using ES6 modules: jquery/PEP#157
  • QUnit is next: jquery/qunit#707

• Improve support for "Web Components" features like ShadowRoot

  • See gh-1748, gh-1784, gh-1976.
  • Several important jQuery APIs like .offset() and .position() break here, but the solution may require changes to the evolving standard.

• Reconcile invalid input behavior across the API. This is to be done in stages.

  • See gh-2134
