Announcing Lift 2.6 M4

Notable Changes

• 2.10 versions of Lift are now built for Scala 2.10.4.
• We are now publishing Lift builds for 2.11, built with Scala 2.11.1.
• MongoRecord.save now has a default true value for its safe parameter.
• Add saveBox, updateBox, and deleteBox_! methods to MongoRecord that catch exceptions and return a Box.
• Moved MongoIdentifier to use a common ConnectionIdentifier shared with other record types.
• Added RecordRules.fieldName, a FactoryMaker that lets you modify a field's corresponding database name based on the database connection and the field's variable name. (#1505).
• Added RecordRules.displayName, a FactoryMaker that lets you modify a field's display name (the name rendered in the UI) based on the record instance being handled, the current locale, and the default display name.
• Added MongoRules.collectionName, an Inject that lets you modify the name of a MongoRecord class's collection based on the connection and the class name.
• Fix MongoListField's setFromJValue to properly handle special mongo data types.
• Add AsObjectId extractor for pattern matching ObjectId Strings.
• Add AsMongoRecord extractor for pattern matching a Mongo Record instance based on an incoming String id.
• Add JsonObjectId, JsonRegex, JsonUUID, JsonDate, and JsonDateTime extractors for lift-mongodb-formatted JValues.
• Added a withFilter method to suppress warnings when using the BaseResponse class in Lift tests (see #1253).
• Wrap mail parts in multipart/related MIME part in emails (see #1569).
• CometActor now handles ResponseShortcutExceptions with redirect responses by sending an appropriate RedirectTo command to the client. This means that e.g. S.redirectTo will work as expected in a CometActor. Note that this is implemented in the default exceptionHandler of CometActor, so if you've overridden it you'll need to make sure that the default handler is something you eventually invoke.
• Added the ability to get a forced version of a request body as JSON or XML, regardless of whether the specified Content-Type of the request was correct. These are Req.forcedBodyAsJson and Req.forcedBodyAsXml, respectively.
• Return a Failure with descriptive error message if bodyAsJson or bodyAsXml are invoked and we don't return the relevant JSON or XML due to an incorrect Content-Type in the request.
• Added a short note on StackableMaker's doWith (used by FactoryMaker, amongst other things) regarding the fact that its changes to its maker's value are thread-local.

Deprecations

• JSONParser, Lift's legacy JSON parser, along with its dependents:
  • MetaRecord.setFieldsFromJSON
  • MetaRecord.fromJSON
  • CometActor's handleJson, jsonCall, and jsonInCode
  • S.buildJsonFunc
  • S.jsonFmapFunc with Any=>JsCmd
  • JsonHandler
  • SHtml.fjsonCall
  • SHtml.jsonButton with Any=>JsCmd
  • SHtml.jsonForm
• Mapper and MetaMapper's snippet bindings that use PartialFunctions:
  • addSnippet, editSnippet, viewSnippet (in favor of addFormSnippet, editFormSnippet, and viewTransform, all based on CSS selector transforms)
  • modSnippet, used in addSnippet and editSnippet, superseded by formSnippet.
  • add, edit, and view snippets in HTML, in favor of addForm, editForm, and viewTransform
  • fieldMapperPF, in favor of fieldMapperTransforms
  • fieldPF, appendField, and prependField, in favor of fieldTransforms, appendFieldTransform, and prependFieldTransform.
• MongoAddress, MongoHostBase, MongoHost, MongoSet and all functions that take them as parameters. Please use the Mongo Java driver's MongoClient instead.
• MongoRecord.save with no parameters. Please use the version with one parameter, and invoke it with empty parens (save()) if you want a safe save. The default for save with no parameters was an unsafe save, which can be achieved using save(false).
• MongoMeta.ensureIndex; use MongoMeta.createIndex instead.
• ListenerManager.updateListeners(Any); use ListenerManager.sendListenersMesage(Any) instead.
