Announcing Lift 3.0-RC1

Breaking Changes

• (#1766) lift-json's \\ used to return a JValue. In cases where it matched a single field directly, it would return the field's value rather than a consistent container type. Matching multiple fields would return a JObject with the matched fields in it. Now, \\ always returns a **JObject** with the matching fields in it, even if there is only one such field. This may require adapting certain uses of \\, especially in for comprehensions. Code like for (JString(name) <- object \\ "name") will have to be changed to something more like for (JField(_, JString(name)) <- object \\ "name") to work correctly. Thanks to @eallik for reporting!
• (#1773), (#1779) Lift was depending on outdated versions of many libraries. We've bumped those dependencies, so we now depend on **specs2 3.7** and **Java Servlet 3.1**. All other version bumps were non-major, including **lift-json-scalaz** now depending on **Scalaz 7.2**. See the dependency file's diff for the full breakdown of dependency updates.

Improvements

• (#1772) When JsCmds including Noop were combined with &, you would get a lot of empty lines, since each Noop would emit some empty lines in those cases. Now, we ignore Noop when combining JsCmds, which should lead to reduced noise in serialized JS output. The most immediate impact is that page-specific JavaScript will be much more compact than it was before. Fixes
• (#1779) Props.whereToLook works correctly again. In **3.0-M8**, we expanded the abilities of Props to read from arbitrary sources. Unfortunately, in the process, we broke the whereToLook setting that allowed you to adjust the search paths for Props to look for named property files. This has been fixed in **RC1**. Thanks to @serioga for reporting!
• (#1769) Lift's JavaScript settings customization was set up such that you couldn't override things provided by **Lift's liftVanilla** or **liftJQuery** objects. This is now fixed, so custom JavaScript settings can build on and override those base functions. Thanks to @joescii for reporting… And fixing! ;)
