    Welcome to YUI Weekly, the weekly roundup of news and announcements from the YUI team and community. If you have any interesting demos or links you’d like to share, feel free to leave a comment below.


This week saw the release of [YUI 3.9.1][1], a patch release that includes bug fixes and enhancements for [Handlebars][2], [LazyModelList][3] fixes, and [Y.Tree][4]. Details of all changes can be found in the [YUI 3.9.1 History Rollup][5].


With the 3.9 release out the door, planning for the next release of YUI is underway! One big thing you can expect to see in the upcoming preview release is Satyen Desai's work on Base performance improvements. By including [these updates][6], we're seeing a 2-5x improvements in the [base-benchmark][7] perf tests in Chrome/OSX. Improvements in Base will affect anything extending it, which includes many parts of the library. Stay tuned!


For those anxious to get started with the new Y.Promise component, documentation is on the way! Here's the [pull request][8


## funkyclosure.js
for (var logLevel in this.levelList) {
    this[logLevel] = (function(logLevel) {
      return function (message,callback) {
        this.logAtLevel(message, this.levelList[logLevel], callback);
      }
    })(logLevel);
  }
});
