1.8.4.1
Issue 1168 - Added lightning:accordionSection component.
Issue 1169 - Fixed a parser issue with {! in HTML/XML comments in Visualforce/Lightning.
Fixed an issue with proper language injection for {!...} formulas in HTML/XML string literals. This seems to be a behavioral regression in IntelliJ IDEA/WebStorm as the previous implementation did work in older builds and evidently stopped working at some point recently. The new implementation should work in all builds.
Updates required for IntelliJ IDEA/WebStorm 2018.3+.
