Highlights
This release includes major improvements from @giffmex to the welcome and tutorial documentation, and new development docs incorporating the work of @cheigele and @cjrk.
Incompatible Changes
Change System Tag $:/tags/stylesheet with $:/tags/Stylesheet
The issue is that the capitalisation of $:/tags/stylesheet is not consistent with other system tags. This release adds support for $:/tags/Stylesheet, and adds a deprecation warning if $:/tags/stylesheet is used. Support for $:/tags/stylesheet will be removed before the beta.
- Added support for 
$:/tags/Stylesheetand a deprecation warning when$:/tags/stylesheetis used 
Change ButtonWidget title attribute to tooltip
The use of the title attribute in the ButtonWidget was not consistent with the tooltip attribute used by the ImageWidget and LinkWidget. This release adds support for the tooltip attribute to the ButtonWidget alongside the existing support for the title attribute, but with a deprecation warning.
- Added 
tooltipattribute to ButtonWidget 
Removing Support for RegExp Filter Operands
As discussed in the associated ticket, the support for regular expression filter operands is incomplete and inconsistent. The plan is to remove support for this feature in the next release. A new filter operator has been provided to replace it, along with the addition of a deprecation warning that is displayed whenever regular expression filter operators are used.
