+* No changes.
+
+3.7.3
+-----
+
+* Fixed Get issues, highlighted by IE10.
+
+  1) IE10 seems to interrupt JS execution, in the case of a 304'ing script to invoke
+  the onLoad handler. If this happened inside the transaction execute loop, the transaction
+  would terminate early (call onSuccess before all scripts were done), because the _waiting
+  count would only reflect the number of scripts added to the DOM, when the loop was
+  interrupted. Changed the logic so that we only finish a transaction when the expected
+  number of requests are accounted for which seems reasonable in general.
+
+  Also wrapped the internal onLoad/onError callbacks in a setTimeout for IE10, so we're
+  re-introducing asynchronicty for external onSuccess, etc. app code. We can take this out
+  when/if the bug below gets fixed.

+
+  2) transaction._finish() would move on to the next transaction, before the current
+  transaction's onSuccess/Finish/End listeners were invoked, since the logic to move to
+  the next transaction was invoked before the `on` listeners were invoked. This meant that
+  for all browsers, when issuing a CSS transaction followed by a JS transaction, the CSS
+  success callback wouldn't be invoked until the JS transaction was initiated.
+
+  3) Added user-agent to feature test for async support, because IE10 wasn't returning true for it.
+  If IE10 ends up fixing the issue below by GA, we'll pull out the explicit ua test.

+
+  ---
+
+  Get should work OK with IE10 now aside from one pending issue. If you issue 2 Get
+  requests to the same 404ing script, IE10 doesn't call the success handler for the
+  subsequent valid (200 etc.) request. This seems to be an IE10 issue, which we cannot
+  control:

+
+3.7.0
+-----
+
+* No changes.
+
+3.6.0
+-----
+
+* No changes.
+
+3.5.1
+-----
+
+* Fixed a bug that could cause CSS requests to hang on WebKit versions between
+  535.3 and 535.9 (inclusive).
+
+
+3.5.0
+-----
+
+* [!] The `Y.Get.abort()` method is now deprecated and will be removed in a
+  future version of YUI. Use the transaction-level `abort()` method instead.
+
+* [!] The `charset` option is now deprecated and will be removed in a future
+  version of YUI. Specify an `attributes` object with a `charset` property
+  instead.
+
+* [!] The `win` option, which allowed you to specify the window into which
+  nodes should be inserted, is now deprecated and will be removed in a future
+  version of YUI. Use the `doc` option instead, which allows you to specify a
+  document, as opposed to a window (which makes more sense).
+
+* [!] The `win` property of transaction objects is now deprecated and will be
+  removed in a future version of YUI. Since any given request in a transaction
+  may now have its node inserted into any document, the best way to get this
+  info is to find the request you're interested in inside the transaction's
+  `requests` property, then look at that request's `doc` property to figure out
+  what document it's associated with.
+
+* [!] The `tId` property of transaction objects is now deprecated and will be
+  removed in a future version of YUI. Use the `id` property instead.
+
+* The Get Utility has been completely rewritten to improve performance and add
+  much-needed functionality. Backwards compatibility has been maintained, but
+  some methods and APIs have been deprecated and will be removed in a future
+  version of YUI.
+
+* Multiple scripts within a transaction are now loaded in parallel whenever
+  possible in browsers that are capable of preserving execution order regardless
+  of load order. This improves performance in those browsers when loading
+  multiple scripts.
+
+* Multiple CSS resources within a transaction are now always loaded
+  asynchronously, since CSS rules are applied based on the order of link nodes
+  in the document, not the order in which resources finish loading. This
+  improves performance in all browsers when loading multiple CSS files.
+
+* Script and CSS resources that fail to load due to HTTP or network errors are
+  now correctly treated as failures in all browsers that support `error` events
+  on script or link nodes. Most browsers support this on script nodes, but only
+  Firefox 9+ currently supports this on link nodes.
+
+* CSS load completion is now detected reliably in older versions of
+  WebKit (<535.24) and Firefox (<9), which don't support the `load` event on
+  link nodes. Unfortunately, while our workaround makes it possible to detect
+  when loading is complete, we still can't detect whether it completed
+  successfully or with an error, so in these browsers CSS resources are always
+  assumed to have loaded successfully.
+
+* Added a `Y.Get.load()` method, which allows you to load both CSS and JS
+  resources in a single transaction.
+
+* Added a `Y.Get.js()` method, which is now the preferred way to load JavaScript
+  resources. `Y.Get.script()` is now an alias for `js()`.
+
+* Added a new `Y.Get.options` property containing global options that should be
+  used as the default for all requests, along with similar `cssOptions` and
+  `jsOptions` properties containing default options that apply only to CSS or
+  JS requests, respectively, and that take precedence over the global defaults.
+
+* Added a new `pollInterval` option, which allows you to customize the polling
+  interval (in milliseconds) used to check for CSS load completion in WebKit and
+  Firefox <=8.
+
+* The `css()`, `js()`, `load()`, and `script()` methods now return an instance
+  of `Y.Get.Transaction`, which encompasses one or more requests and contains
+  useful properties and methods for getting information about and manipulating
+  those requests (and related HTML nodes) as a unit.
+
+* The `css()`, `js()`, `load()`, and `script()` methods now accept an optional
+  Node.js-style callback function as either the second or third parameter. This
+  function will be called after the transaction finishes. The first argument
+  is an array of errors, or `null` on success. The second argument is the
+  transaction object.
+
+* The `css()`, `js()`, `load()`, and `script()` methods now accept URL strings,
+  objects of the form `{url: '...', [... options ...]}`, or arrays of URL
+  strings and/or objects. This allows you to specify per-URL options if desired,
+  such as node attributes, parent documents, `insertBefore` nodes, etc.
+
+* The logic used to determine where a node should be inserted when no custom
+  `insertBefore` node has been specified has changed slightly. By default,
+  script and link nodes will now be inserted before the first `<base>` element
+  if there is one, or failing that, before the last child of the `<head>`
+  element, or if there's no `<head>` element, before the first `<script>`
+  element on the page.
+
+* The source for the `get` module has moved from `src/yui` to `src/get`. This
+  allows it to be built separately from the core YUI modules.
+
+
+3.4.1
+-----
+
+* No changes.
+
+
+3.4.0
+-----
+
+* Added an `async` option to `script()`. When set to `true`, the specified
+  scripts will be loaded asynchronously (i.e. in parallel), and order of
+  execution is not guaranteed. The `onSuccess` callback will be called once,
+  after all scripts have finished loading.
+
+* Added an `onProgress` callback, which is useful when loading multiple scripts
+  either in series or in parallel by passing an array of URLs to `script()`.
+  The `onProgress` callback is called each time a script finishes loading,
+  whereas `onSuccess` is only called once after all scripts have finished
+  loading.
