• Update the TEXTINPUT event name to be 'textinput' instead of 'textInput' for IE, as IE does not fire event listeners for the camel-cased version.
• stop sealing functions directly assigned to goog.module exports values.

Closure Library v20160911

New Additions

• New selection change event type enum entry.
• Support for TEMPLATE tags. Added a method to turn off TEMPLATE tag content sanitization on browsers that support the TEMPLATE tag.

Backwards Incompatible Changes

• This changes the type of goog.dom.TagName members from string to object instances used to infer the type of created or got elements. This breaks string-only uses of goog.dom.TagName members such as in "case el.tagName" statement or with strict comparison ===. Most uses (passing goog.dom.TagName members to functions such as goog.dom.createDom or non-strict comparison ==) are unaffected. Closure Compiler unconditionally converts goog.dom.TagName members to strings which means that compiled code will still work even with string-only uses. Uncompiled code needs wrapping goog.dom.TagName members to String() in string-only context.
• goog.dom.forms.submitFormDataInNewWindow and goog.dom.forms.submitFormInNewWindow now works with form fields whose name shadow existing dom methods.

Other Changes

• Fix Chrome console warning when using goog.events.KeyHandler due to accessing deprecated KeyboardEvent.keyIdentifier.
• Update transpile.js, fixes bug in transpiling "for" loops using "let" or "const" declarations.
• Do not validate strict goog.require while goog.ENABLE_DEBUG_LOADER is false.
• Fixed numberformat (scientific) so it doesn't hang on specific very small numbers (say 5E-324) that are representable but for their exponent Math.pow(10, exponent) would return 0.

• Add goog.dom.TypedTagName and allow using it in goog.dom.createDom and similar.

Backwards Incompatible Changes

• The @define for disabling debug-loader transpilation has changed from goog.NEVER_TRANSPILE=true to goog.TRANSPILER="".
• goog.math.Rect now implements goog.math.IRect. Additionally, most methods now accept IRect rather than just goog.math.Rect. This allows operations between things like ClientRect and goog.math.Rect.

Other Changes

• Fix the .replace metacharacters handling in editor/plugins/removeformatting.js
• Update the debug loader transpiler.
• Few performance fixes to goog.html.sanitizer.sanitize.

The default mode is atLeast(1) which was the default behavior of verify without VerificationMode. VerificationError messages have been updated to include a description from the VerificationMode about what was expected.
• Add goog.soy.Renderer.renderSafeStyleSheet()
• Added goog.array.concatMap method.
• Add goog.html.sanitizer.sanitize (returns a SafeHtml from an untrusted String)
• Debug loader will now optionally transpile if {'lang': 'es6'} is passed to goog.addDependency and "transpile.js" is available in the same directory as "base.js".
• Added iPod detection in useragent.js and iPod OS version detection in platform.js.
• Add new public method getUserSelectableDateRange to goog.ui.DatePicker.
• Added fireFocusInEvent to goog.testing.events.
• Allow testSuites to have a name via the getTestName() method on the test object.

• Delete deprecated goog.string.linkify.linkifyPlainText.
• Breaking change for third parties: This will break your build if your code uses goog.ui.Dialog#setContent. Use setSafeHtmlContent or setTextContent instead. The method is removed because its usage can cause XSS. goog.ui.Dialog#setSafeHtmlContent or goog.ui.Dialog#setTextContent provide a safe alternative (unless the SafeHtml is constructed using legacyconversions).
• MockControl's createFunctionMock now has non-nullable @return to match goog.testing.createFunctionMock
• Breaking change for third parties: This will break your build if your code uses goog.dom.htmlToDocumentFragment or goog.dom.DomHelper#htmlToDocumentFragment. Use goog.dom.safeHtmlToNode or goog.dom.DomHelper#safeHtmlToNode instead.
• goog.labs.object.is is now goog.object.is
• Change goog.labs.mock such that later calls to #when create stubs which take precedence over previously created stubs. The previous behavior of later calls creating sequential stubs is exposed via chaining #then or #thenReturn calls to the same invocation of #when. With these changes the API now more closely matches the Java Mockito library as originally intended.

Other Changes

• labs.testing.Environment: Enable returning a promise from user defined setUp method.

• Support drag and drop for Opera 15 and above
