- IMPROVED: if you use ScrollTrigger to pin something inside a pinnedContainer (and both have pinSpacing), it'll now adjust the padding/sizing of that pinnedContainer's pin-container element. So nested pinning has better support now.

- IMPROVED: Previously, MotionPathHelper would only set the pathColor, pathWidth, and opacity if the path that was defined wasn't an svg <path> (if it created a new one), but now it'll honor those properties even if you're using an existing path. See https://greensock.com/forums/topic/34009-arguments-in-the-motionpathhelper-function-are-ignored/

- IMPROVED: added a console.warn() for when you forget to define a "content" element for a ScrollSmoother.

- IMPROVED: MotionPathHelper is gsap.context()-aware and has a kill() method for better management.

- FIXED: regression in 3.11.2 that could cause a .fromTo() tween to render its starting values immediately after .revert() is called. See https://greensock.com/forums/topic/34016-fromto-not-reverting-inline-styles-as-expected/

- FIXED: if you set a pin value in a ScrollTrigger and fail to set any pinSpacing (true or false) and the pin element's parentNode is NOT a valid Element, it could throw an error. See https://greensock.com/forums/topic/34021-pinned-element-using-scrolltrigger-breaking-the-flow-on-litdev-app-error-failed-to-execute-getcomputedstyle-on-window-parameter-1-is-not-of-type-element

- FIXED: if ScrollTrigger.refresh() is called when a ScrollTrigger is pinned and the scroll position is not at the very top/left, it could render that pinned element incorrectly.

- FIXED: When calling ScrollTrigger.refresh(), it may (in certain circumstances) cause ScrollSmoother to jump to the top. See https://greensock.com/forums/topic/33877-scrollsmoother-scrolling-to-top-with-scrolltriggerrefresh/

- FIXED: if you enable snapping on a ScrollTrigger and have scroll-behavior: smooth on the scroller, it may not settle properly. 3.11.3 sets scroll-behavior to auto automatically in that condition now.

- FIXED: if you call setPositions() on a ScrollTrigger that pins and has pinSpacing, it'll adjust the pin spacer's height/padding accordingly rather than just changing the start/end.

- FIXED: in 3.10.0, ScrollTrigger switched to waiting for a requestAnimationFrame() tick to update after a "scroll" event, but newer version of Safari repaint earlier which could lead to things looking jerky in certain cases, so we switched back to immediately updating ScrollTrigger on every "scroll" event. See https://greensock.com/forums/topic/34062-greensock-scrolltrigger-animation-jumping-when-scrolling/

- FIXED: in some rare cases, a ScrollSmoother-based page couldn't be scrolled all the way to the bottom. This is usually related to nested pins. See https://greensock.com/forums/topic/34056-nested-pins-dont-work/
