OpenSeadragon is truly a community project; we welcome your involvement!
When contributing, please attempt to match the code style already in the codebase.
However, we are in the process of changing our code style (see issue [#456](https://github.com/openseadragon/openseadragon/issues/456)), so avoid spaces inside parentheses and square brackets. Note that we use four spaces per indentation stop. For easier setup you can also install [EditorConfig](http://editorconfig.org/) if your IDE is supported. For more thoughts on code style, see [idiomatic.js](https://github.com/rwldrn/idiomatic.js/).

OPENSEADRAGON CHANGELOG
=======================
3.0.0: (In progress)
4.0.1: (in progress...)
* The viewer no longer emits canvas-key events for both keydown and keypress events; canvas-key is now just for keydown, and the new canvas-key-press is for keypress (#2270 @hrghauri)
* You can now specify a priority when calling addHandler, to control when your event handler gets called relative to others (#2273 @Aiosa)
* Added tileRetryMax and tileRetryDelay options, so the viewer can retry loading failed tiles (#2238 @Ughuuu, @paaddyy)
* Fixed: Navigator display rectangle was off if the page had box-sizing: border-box (#2276 @ambujsahu81)
* Fixed: Code that required identifying functions would fail for async functions (#2273 @Aiosa)
* Fixed: Reference strip click detection was not accurate for long reference strips (#2280 @damonsson)
4.0.0:
* NEW BEHAVIOR: Setting the viewport rotation now animates by default (pass false for the new `immediately` parameter to disable) (#2136 @jonasengelmann)
* NEW BEHAVIOR: The auto resize now takes both width and height into account when scaling the contents proportionally to the viewer (#2256 @pearcetm)
* DEPRECATION: Don't access the viewport's degrees property directly anymore; instead use setRotation and getRotation (#2136 @jonasengelmann)
* New gesture: Double-click and drag to zoom (on by default for touch) (#2225 @HamzaTatheer)
* You can now provide a pivot point when rotating the viewport (#2233 #2253 @pearcetm)
* Improved the constraints that keep the image in the viewer, specifically when zoomed out a lot (#2160 @joedf, #2246 @pearcetm)
* You can now provide an element for the navigator (as an alternative to an ID) (#1303 @cameronbaney, #2166 #2175 @joedf)
* Now supporting IIIF "id" and "identifier" in addition to "@id" (#2173 @ahankinson)
* We now delegate tile fetching and caching to the TileSource, to allow for custom tile formats (#2148 @Aiosa)
* Added support for dynamic URLs from tile sources (#2247 @JohnReagan)
* The viewer now emits before-destroy and destroy events (#2239 @pearcetm)
* Auto resize detection is now more efficient (#2256 @pearcetm)
* Improved documentation (#2211 @shyamkumaryadav)
* Fixed: Cropping tiled images with polygons was broken (#2183 @altert)
* Fixed: Boundary constraints were wrong when the viewport was rotated (#2249 @pearcetm)
* Fixed: IIIF tile sizes would be calculated wrong on rare occasions (#2206 @filak)
* Fixed: Disabling buttons only changed their appearance, but they were still clickable (#2187 @pearcetm)
* Fixed: ImageTileSource produced an error having to do with getTileHashKey (#2190 @Aiosa)
* Fixed: On startup you would get an unnecessary "Viewer.buttons is deprecated" warning (#2201 @joedf, #2219 @jssullivan, #2212 @joedf)
3.1.0:
* Added subPixelRoundingForTransparency Viewer option to address seams that can appear in semi-transparent images (#2075 @TanukiSharp)
* Added Viewer.isAnimating() (#2075 @TanukiSharp)
* Added isFullScreen method to Viewer (#2067 @JachiOnuoha)
* Added option to include POST data when loading files via Ajax (#2072 @Aiosa)
* Exposed TiledImage's private functions for better maintainability (#2134 @Aiosa)
* Tile cache keys are now generated by the tile source, so it's easier to override them as needed (#2138 @Aiosa)
* Pinch to zoom now zooms around the center of the pinch, rather than the center of the viewer (#2158 @cavenel)
* Added fallback and deprecation warning for Viewer.buttons (which got changed to buttonGroup in 3.0.0) (#2153 @devbyjonah)
* Fixed an issue where turning off panVertical or panHorizontal would not affect the panning keyboard combos (#2069 @JachiOnuoha)
* Cleaned up console.logs so that errors and warnings use console.error and console.warn as appropriate (#2073 @Abhishek-90)
* Improved documentation (#2067 @JachiOnuoha, #2112 @shyamkumaryadav, #2152 @joedf, #2155 @samwilson)
* Fixed: Setting useCanvas to false would break the viewer (#2116 @rvv-bouvet)
* Allow silencing multi-image warnings on viewport coordinate conversion functions (#2120 @claycoleman)
* Fixed: Swiping fast multiple times made contact points in MouseTracker out of sync for touch events (#2121 @ronnymikalsen)
* Made MouseTracker more robust in certain scenarios (#2134, #2147 @Aiosa)
* Fixed an issue where full page mode wouldn't grow properly if you resized the window (#2100 @TanukiSharp)
* Now if you pass an error handler into makeAjaxRequest, it doesn't report errors into the console (#2142 @Aiosa)
* Fixed error caused by attaching MouseTracker to the page's document element (#2145 @tdiprima)
* Fixed an issue that would sometimes cause problems with freeing up ImageTileSource memory (#2162 @pearcetm)
3.0.0:
* BREAKING CHANGE: Dropped support for older browsers (IE < 11) (#1872 #1949 #1951 @msalsbery, #1950 @rmontroy)
* BREAKING CHANGE: Removed deprecated OpenSeadragon.getEvent function (#1949 @msalsbery)
@ -55,6 +108,10 @@ OPENSEADRAGON CHANGELOG
* Now ensuring that the new item is already in the navigator when the "add-item" event fires (#2005 @RammasEchor)
* Added keys to change image in sequence mode (j: previous, k: next) (#2007 @RammasEchor)
* Fixed a bug where the navigator wouldn't pick up opacity/composite changes made while it is loading (#2018 @crydell)
* Explicitly set passive:false for wheel event handlers to suppress console warnings. Fixes #1669 (#2043 @msalsbery)
* Viewer's canvas-click events now include an originalTarget property so you can know which element received the click (#2037 @iangilman)
* Added method for getting the size of an image in window coordinates (#2049 @superbland)
* Added a setMaxLevel function to TileSource so you can change its maxLevel if needed (#2059, #2066 @kim-sanghoon)
