This document lists the changes in the different releases

1.4.0.2

• Features
• Added PlaylistID and PlaylistTitle support to the subscription entries in youtube feeds, added support for subscriptions to the Google.YouTube namespace
• Added Google Contacts v2 support, including a new, vertical model like the YouTube programming model. You can find this in the Google.Contacts namespace.
• Added Batch access to the new generics model. You can now create a FeedRequest object, and use it's Batch method to send a List of entry objects to the server. Entry and Feed expose access to the batch data.
• Added Google Documents v2 support including the new download functionallity
• Added a new Google Documents exporter sample. It allows you to populate a treeview with your Google Documents and then export each individual file in a variety of formats.
• Extended the YouTube Notifier sample to use the User Events feed as well.
• Bugfixes/changes
• Added the missing contacts DLL to the setup program.
• Changed the new Feed model code to lazily load the feed on construction.
• Removed the CreateInstance methods from the new feedmodel and changed the internals to lazyily create the inner objects on demand. That means, no more Video v = Vidoe.CreateInstance() in your code, but Video v = new Video() is now fine.
• Removed an incorrect check for HTTP.StatusOK (200) as the result for an HTTP.Delete operation. Delete can return any 2xx code in theory.
• Fixed issue 209, an feed.Entries.Add(entryOfAnotherFeed) did create a source element automatically. That was too smart for it's own good. There is an explict method Entries.MoveOrCopy(entry) that does that, add will just change the ownership to the new collection.
• Changed Google.Client.Entry.ID to Google.Client.Entry.Id
• fixed the feed.Entries iterator to restart from the beginning when you want to use it again. Note that you should cache the output of the iterator is you want to use that in a loop.
• Fixed issue 217, a call to setUserCredentials now automatically invalidates a stored authtoken.
• Fixed issue 200. A feedQuery now supports an etag property, and several new service method overloads for query and send support an etag as a parameter.
• Service.Query(FeedQuery, ifModifiedSince) is now marked obsolete. You can use the ModifiedSince property on the FeedQuery object and Query(FeedQuery) instead.
• Added the ability to store a client token to GDataCredentials. Setting the credentials property will take this into account.
• Changed the base apps feed uri for Google Apps
• Changed GBatchStatus and GBatchError to use the correct namespace, it was incorrectly using the prefix instead.
• fixed issue 218, setting org.Title or org.name in a contact to null or an empty string did not remove the element.
• fixed issue 203, you can now retrieve the ACL feed for a document
• fixed issue 200, feedquery now has an etag property to create if-match queries.
• Fixed issue 221, setting private to false in an YouTubeEntry resulted in failure to persist that entr.
• Added a setter for Entry.Id
• Added a batch method for Feed
• YouTube.Video.VideoId now has a setter
• YouTube.YouTubeRequest has an AddComment method.
• Google.Client.FeedRequest has a new Get(Uri uri) method
• Added AppControl and IsDraft accessors to Google.Client.Entry
• Added a Get(uri) method to the Google.Client.FeedRequest
• Fixed YouTubeEntry.State to actually parse and return the yt:state element
• Added property accessors to YouTube.State
• Added a State property accessor to Google.YouTube.YouTubeRequest
• Added a GetVideoMetaData method to YouTubeRequest
• Changed Get on the FeedRequest to Retrieve for single entries. This was required for the new overloads introduced. Also, as Retrieve directly accesses the service, compared to Get wich is defered, a name change is a good distinction.
• Video.Rating, ViewCount and CommentCount returns -1 as default if no value was found.
• Lot's of addtions to the Entry Model and it's subclasses. Check the documentation for details

1.3.1.0

• Features
• Added a mergemodule for the Core libraries.
• Added a mergemodule for the YouTube libraries.
• Added a new sample application for YouTube, the YouTube Notifier
• Added a YouTubeQuery.GetYouTubeCategories method that returns a collection of category objects based on parsing the youtube category file hosted on the web.
• YouTube project template.
• New, simpler, YouTube object model. Look at the items in the new Google.YouTube namespace. This new code is used in the YouTube Sample application, the template above, and the youtubetest.cs file in the unittests.
• Added a ModifiedSince property on the FeedQuery object. If set to something different than DateTime.MinValue this results in an if-modified-since HTTP header produced if the FeedQuery is used in a Service.Query call.
• OAuth support for two-legged authentication. Look in samples/OAuth for a usage example. Code for this graciously provided by Andrew Smith and Eran Sandler. Note that due to different support on the Compact Framework, this is not available in the Windows Mobile build.
• Bugfixes/changes
• Fixed issue 198. HealthEntry.CCR returned null, as a wrong cast after the recent refactory that happened to the extensions returned always null.
• Fixed issue 195. Service.Update could call itself, resulting in recursion.
• Fixed bug 194. CreatePicasaUri was confusing because it used the albumname as a parameter compared to an albumid. Changed to now use an AlbumID.
• Removed the ASP build and marked the standard release assemblies as Partially Trusted.
• Fixed issue 191, Overloaded AuthSubUtil.getRequestUrl(hostedDomain, nextUrl, scope, secure, session) is broken
• Fixed issue 189, Cannot select Contacts by group
• Fixed an issue in AlbumEntry Accessor for Picasa, where ComentingEnabled accidently set the wrong element in the xml
• Removed the Service(service, application, library) constructor as this variation did not use the passsed in information. If you used this, just remove the 3rd parameter.
• Entry.Update and Entry.Delete will now thow an InvalidOperationException when they are called without a valid service object being set, instead of not doing anything silently.
• Removed the usage of StringCollection and replaced it with a generic List
• CommentingEnabled was accidently setting the CommentCount element.
• Made the created useragent string more uniform and meaningful
• AtomFeed.Entries are not an ILIst<> an no longer an arraylist.
• Fixed several v2 related YouTube issues

1.2.3.0

• Features
• Added support for EMail Settings in Google Apps
• Added support for the protocol version 2
• YouTube will work against version 2 of the protocol by default. Added support for the version 2 of the YouTube feed. Old methods are marked as obsolete and will be removed in future releases.
• Bloogger will work against version 2 of the protocol by default.
• Created a blogger service, feed, entry and query class. The query class allows the OrderBy parameter. This also fixes issue 151 on the public issue list. Added a PostUri method to the blogger entry.
• Added the Error subelement collection to GDataBatchStatus. Removed the Value element as it was not used.
• Issue 166: Added a GetTokenInfo helper method that returns a Dictionary with the Information returned about the authentication token.
• Added a bool property Private to the YouTubeEntry identifying if a video is private
• Added a script to create a linux friendly tarball
• Issue 165: Added the ability to access the error collection from inside the batch error.

• Fixed issue 154: you can now access the publishing priority element on a GBaseEntry directly.
• Fixed issue 176: onProgress events were potentially not being raised in the Async Methods.
• Fixed issue 178: Groups feeds on the contacts service did not work when using https.
• Fixed issue 180: Passwords with some special characters were incorrectly encoded, leading to a failure in authentication.
• Removed the version dependency for the NUNIT tests, so that the tests can now be used with different installed versions of the NUNIT framework.
• Some typographical changes. getExtensionValue and setExtension are now named GetExtensionValue and SetExtensionValue
• Unknown extension elements are now stored in a Wrapper XmlExtension element, which implements the usual IExtensionElements interfaces to enable removing untyped lists internally.
• Moved the core of the extension functionallity, so just the base classes, into the Google.GData.Client, so that the base AtomFeed/AtomEntry can be extended using this extension system. Otherwise there would be a circular reference between client.dll and extension.dll

1.2.2.0

• Features
• Added a SetRequestFactory method on the AppsService. This allows a user of the AppsService to set advanced HTTP properties for the underlying service objects used (like setting a proxy server, additional headers etc.) by creating a new RequestFactory object and passing it into the service. To make it easy to create this factory object a helper CreateRequestFactory was added to the AppsService object as well.
• Asyncronous/background support including a sample application. You can now easily fire off that long running YouTube upload, or the download of a picture as a seperate thread, so that your main application is no longer blocked. It uses the AsyncOperation pattern, and is not available (due to missing base support in the compact framework) in the Windows Mobile build.
  The sample PhotoBrowser application was changed to use that pattern, and a page in the helpfile introduces the concept.
• Added support for Issue 163: the calendar recently introduced several new elements, this adds support for syncEvent, uui and sequence
• Bugfixes
• Fixed a bug in CommentingEnabled on the PhotoAccessor, which was setting internally the wrong property.
• Changed the behaviour of AlbumEntry.AlbumAuthor. The setter will now create a new author is no author is present.
• Fixed an issue regarding content, type=text. This element was not encoding correctly which could lead to server errors based on the contents of the element.
• Fixed issue 164, the code will now throw an exception if we get an empty location header in a redirect situation
• Fixed issue 161, changed the WebProxy property on the RequestFactory object to IWebProxy to make this interface more flexible.
• Removed an obsolete size check for the authentication response for client login and login for webapplications.
• Fixed issue 160, FirstName in the profile feed of YouTube was spelled wrong and hence not loaded correctly.
• Fixed issue 157, Slug Header encoding. This was not correctly confirming to RFC5023. Introduced a new helper method in the utilities class for this purpose.
• Fixed issue 147, a composite feed with a comment was not loading
• Fixed issue 148, RemoveAt did not remove the object from the containing collection, only locally. Fixed by overriding the OnRemove method.
• Fixed issue 155, there was no way to create a read only youtube service, or rephrased, one that did not require a developer key
• Fixed issue 159, a typo in the makefile that prevented gac install/uninstall
• Fixed issue 156, if an exception happened during upload, the resource was kept open
• Fixed issue 149, the Who element failed to parse attendee status if a whitespace element was encountered
• Fixed issue 144, recurrenceexception is not parsed correctly
• Fixed issue 145, FeedLink element parser error
• Fixed issue 146. Passwords containing percentage signs were not properly encoded.

1.2.1.0

• Features
• Added media:rating to media:group
• Added the most-popular constants to the defined youtube queries
• Added missing convienience classes to YouTube (Comments, Complaints etc, check the YouTube documentation)
• Added PDF support to the Google Documents API
• Added a CategoryQueriesAsParameter property on the feedquery class, and making that false by default. On the YouTubeQuery this is true by default. The effect is that category queries will not be created by extending/changing the path portion of the URL, but instead using a new parameter "category" and putting the categories comma delimited into the query part of the uri.
• Bugfixes
• Fixed issue 135. There was a bug in the FeedQuery parsing code that resulted in URIs with date parameters that are encoded to potentially throw
• Removed the Cookie property and replaced it with a Cookies properter on the RequestFactory. The old code, using just a simple string, was implemented for mobile benefits, as the CookieContainer, that is used now, does not exist on the compact framework. The simple solution though is creating problems in some scenarios, and had to be removed.
• Added over 100 more unittests for the YouTube service
• Fixed issue 102, 142

1.2.0.0

• Features
• Added support for the gd:rating element
• Added direct properties for Url, Height, Width for the MediaThumbnail

• Created a real app:control extension. This one is currently only used in the YouTube namespace.
• Added support for YouTube
• Added support for Google Health
• Added HealthTool in the samples directory as a supporting tool for Google Health
• Added support for the timeout property of the http request. You do this by setting tbe timeout on the GDataRequestFactory to something else than -1, which indicates the default of the created HTTPRequest object.
• Added support for the new Contacts feed.
  • ContactEntry now has a collection of ExtendedProperties
  • ContactEntry now has a collection of GroupMemberships
  • The ContactsQuery.CreateContactsUri returns a FULL projection now by default. There is a new CreateContactsUri(user,projection) to get the old behaviour, or get other projections
  • There is a new ContactsQuery.CreateGroupsUri helper
