v3.3.0

• big re-write on how cellHeight() works. you can now call it at any time (not just grid init options) including switching to 'auto' or other modes on the fly.
• fix cellHeight:auto now keeps cell square as window resizes (regressing from 2.x TS conversion). Utils.throttle() works better too (guaranteed to be called last event)
• new cellHeight:initial which makes the cell squares initially, but doesn't change as windows resizes (better performance)
• new grid option cellHeightThrottle (100ms) to control throttle of auto sizing triggers
• fix 1600 height too small with cellHeight:auto loading in 1 column. Now detect we load at 1 column and size accordingly (default 'auto' could make big 700x700 cells, so explicit px might still be wanted)
• fix 1538 loading nested into small size and sizing back up
• fix 1604 nested grid resizing fix
• fix 1599 H5 resize from left side can move item right

v3.2.0

• fix 1413 website & lib works on mobile. We now compile the latest v1.0.8 jquery.ui.touch-punch
  into the JQ version (only 2k) so mobile devices (android, iphone, ipad, ms surface, etc...) are supported out of the box.
  HTML5 version will require re-write to plain mousemove & mobile touchmove instead of drag events in a future release.
• small optimizations (create placeholder content on the fly, moved more DD code into draggable class)

v3.1.5

• fix 1572 column: N option now sets CSS class so you don't have to
• fix 1571 don't allow drop-in when grid is full
• fix 1570 easier to drag out/in from below
• fix 1579 cellHeight() was not updating CSS correctly
• fix 1581 H5 draggable by actual div handle rather than entire item (let content respond to drag as well)

v3.1.4

• fix 1557 no-drop cursor on windows when dragging within a default grid (no external drag in)
• fix 1541 Safari H5 delay when dropping items

v3.1.3

• fix #1540 Safari H5 drag&drop now works (some issue remain #1550 and #1541)
• fix #1535 use batchUpdate() around grid init to make sure gs-y attributes are respected.
• fix #1545 disableMove() correctly prevents drag later (remove events and draggable attribute)
• fix #1546 resize no longer delayed, which caused race conditions errors
• fix #1001 resizing near bottom/top needs to auto-scroll. thanks @hbcarlos!

v3.1.2

(fixed bundle size in 3.1.1)

• fix #1419 dragging into a fixed row grid works better (check if it will fit, else try to append, else won't insert)
  possible BREAK (unlikely you use engine directly)
  engine constructor takes Options struct rather than spelling arguments (easier to extend/use)
  canBePlacedWithRespectToHeight() -> willItFit() like grid method
• fix #1330 maxW does not work as intended with resizable handle "w"
• fix #1472 support all options for new dragged in widgets (read all gs-xyz attributes)
• fix #1511 dragging any grid item content works
• fix #1438 web-component fixes & grid with 0 size initially. (edited)

v3.1.0

• add new addGrid(parent, opts) to create a grid and load children instead of init() + load(), which is used by load() to supports nested grids creation.
  see nested.html demo.
• save() will now work on nested grids, recursively saving info. added flag to also allow saving the current grid options + children
  (needed for nested grids) so you can now call new adddGrid() to re-create everything from JSON.
• fix 1505 don't call movable()/resizable() on locked items error. thanks @infime
• fix 1517 force typescript 3.6 as 3.7+ has breaking change forcing apps to be at least 3.7 (we only used one tiny feature in newest TS, not worth the incompatibility).

v3.0.0

• the big news is we finally have a native HTML5 drag&drop plugin (no jquery/query-ui, entire bundle now at 1/3 the size 64k), in addition to legacy jq one (186k), and new static grid bundle (34k). Huge thanks to @rhlin for creating this in stealth mode. Read all about it in main doc.
• we now have a React example, in addition to Vue - Angular is next!. thanks @eloparco
• fix placeholder not having custom GridStackOptions.itemClass. thanks @pablosichert
• fix #1484 dragging between 2 grids and back (regression in 2.0.1)
• fix #1471 load() into 1 column mode doesn't resize back to 12 correctly
• fix #1235 update(el, opts) re-write to take all GridStackWidget options (not just x,y,width,height) and do everything efficiently.
  Hiding locked(), move(), resize(), minWidth(), etc... as they just simply call update() which does all the constrain now as well!
• delete ddPlugin grid option as we only have one drag&drop plugin at runtime, which is defined by the include you use (HTML5 vs jquery vs none)
• BREAK: change attribute data-gs-min-width is now gs-min-w. We removed 'data-' from all attributes, and shorten 'width|height' to just 'w|h' to require less typing and more efficient (2k saved in .js alone!) #1491 #1492
• BREAK: also GridStackWidget used in most API width|height|minWidth|minHeight|maxWidth|maxHeight are now shorter w|h|minW|minH|maxW|maxH as well #1493
• **** see migrating to v3 ****

v2.2.0

• add margin option now support multi values CSS format '5px 10px 0 20px' or '5em 10em'
• add data-gs-static-grid attribute
• fix class="ui-draggable-disabled ui-resizable-disabled" have been added back to static grid items, so existing CSS rule to style continue working #1435
• fix getting DOM element by id with number works (api that uses GridStackElement handle more string formats)
• fix setting marginTop (or any 4 sides) caused resize to break. Marking legacy as I recommend using new margin format. Thanks @deadivan for suggested fix.

v2.1.0

• fix grid static: true to no longer add any drag&drop (even disabled) which should speed things up, and setStatic(T/F) will now correctly add it back/delete for items that need it only.
  Also fixed JQ draggable warning if not initialized first #858
• add addWidget(opt) now handles just passing a GridStackWidget which creates the default divs, simplifying your code. Old API still supported.
• add save(saveContent = true) now lets you optionally save the HTML content in the node property, with load() restoring it #1418
• add GridStackWidget.content now lets you add any HTML content when calling load()/save() or addWidget() #1418
• add ColumnOptions to column(n, options) for multiple re-layout options, including 'none' that will preserve the x and width, until out of bound/overlap #1338
  including a custom function for you to create the new layout #1332
