3.6.3: Fix for when/callbacks

• Fix regression in when/callbacks introduced in 3.6.1

3.6.2: Work around v8 bug, fix regressions

• Work around v8 optimizing compiler bug with some truly amazing help from community members. Thank you @anodynos, @jefflage, @kidkarolis, @pbarnes, @spion, @tsouza.
• Fix regressions in when.filter and when.reduce (which also affected when/sequence).

3.6.1: More perf improvements

• Significant improvements to when.try, and when.lift.
• Additional improvements to array functions: when.reduce, when.any, and when.some.
• Improved handling of early bail-out cases in when.all, when.map, and when.any.

3.6.0: Significant perf and mem improvements

• Significant performance improvements:
  • 10x or more for when.map, especially for large arrays
  • ~2x for when.reduce and promise.fold
  • ~1.5-2x for generators using when/generator lift, call, and/or apply.
• Memory use reductions for when.reduce and promise.fold.

3.5.2 Accept Arguments objects in when/function

• when/function.apply now handles passing an Arguments object directly, e.g. fn.apply(f, arguments);.
• Prevent minifiers from clobbering unhandled rejection reporting if they remove console.* calls. For example, unhandled rejections will be reported even when using Uglify drop_console.

3.5.1: Improve race errors and environment support

• when.race & Promise.race now reject with a TypeError if you pass something that is not iterable.
• Improve scheduler compatibility with MutationObserver shims
• Simplify checks for vert.x environment

3.5.0: Improve race performance

• Improve when.race & Promise.race performance.
• Internal changes to start paving the way toward 4.0.0.
• Deprecate when.iterate and when.unfold. Use cujoJS/most for streaming asynchronous values.
• Deprecate progress events. See the docs for more information and tips on refactoring code that uses promise progress.

3.4.6: Ensure webpack compatibility

• Ensure webpack compatibility by excluding vertx from browser bundles

3.4.5: Improve unhandled rejection reporting

• Fixes for edge cases for unhandled rejection reporting

3.4.4: Workaround node 0.10.30 setTimeout bug

• Workaround for node 0.10.30 setTimeout bug. See this issue
