| 6 | +--- |
| 7 | + |
| 8 | +Today we are releasing Milestone 3 of the Scala IDE V2.1.0, available for both Scala 2.9 |
| 9 | +and 2.10.0-RC5. The highlights of this release are an improved Scala Debugger, JUnit4 |
| 10 | +support, better relevance metrics in code completion, and several stability improvements |
| 11 | +for mark occurrences and semantic highlighting. |
| 12 | + |
| 13 | +Let's have a quick round at what happened in the past four months. |
| 14 | + |
| 15 | +### Scala Debugger |
| 16 | + |
| 17 | +While debugging, have you ever tried to *step over* a ``map`` or ``foreach`` call on a |
| 18 | +collection class? Sure you have! And, didn't you find it annoying that the existing Java |
| 19 | +debugger would not actually step *inside* the closure passed in argument? |
| 20 | +Or, have you ever needed to look at the content of a Scala ``List`` in the debugger view? |
| 21 | +Then you know that to check its content you need to **manually** unfold the list. |
| 22 | +Sounds like something a debugger should do for you. |
| 23 | + |
| 24 | +The Scala Debugger has gone through some heavy restyling, and we believe it is now ready |
| 25 | +to be adopted as the default debugger; make sure to use it every time you are chasing down |
| 26 | +a bug. Since last milestone we have improved it in many ways, and we kept on adding new |
| 27 | +features. For instance, we now have support for remote debugging, enabling/disabling |
| 28 | +breakpoints during execution, step filters for Scala specific features (yes, the Scala |
| 29 | +Debugger knows it's debugging Scala code!) and much more. |
| 30 | + |
| 31 | +Keep reading [here][scala-debugger] to find out about the supported features and how to |
| 32 | +make it the default debugger for all your Scala projects. |
| 33 | + |
| 34 | +### JUnit4 Support |
| 35 | + |
| 36 | +Many of you have been asking for better JUnit4 support; we heard you. With this milestone |
| 37 | +we ship a completely re-written module to fully support automatic lookup and execution of |
| 38 | +both your Scala and Java JUnit4 tests. Right click on a project, package or source, and |
| 39 | +run your tests via the ``Scala JUnit Test`` runner. |
| 40 | + |
| 41 | +You can read more about the Scala JUnit4 runner [here][scala-junit4] |
| 42 | + |
| 43 | +### Editor Enhancements |
| 44 | + |
| 45 | +We have also found the time to squeeze in some great enhancement: |
| 46 | + |
| 47 | +* Code completion proposals are now sorted according to their distance, i.e., local |
| 48 | + definitions (local variables, local methods) are shown at the top. |
| 49 | + |
| 50 | +* A brand new Quick Fix for automatically correct your code when a *type missmatch error* |
| 51 | + occurs. For instance, if a method expects an ``Option[T]`` to be returned, and your |
| 52 | + implementation currently returns a value of type ``T``, you will get a suggestion to |
| 53 | + wrap the returned value in an ``Option.apply``. |
| 54 | + |
| 55 | +### General improvements |
| 56 | + |
| 57 | +We have been fixing over 90 tickets since milestone 2 was released. You will notice many |
| 58 | +stability improvements affecting the Scala editor, semantic highlighting and update |
| 59 | +occurrences. You want to know all the glory details? Have a read at the |
| 60 | +[changelog][changelog]. |
| 61 | + |
| 62 | +## Install it now! |
| 63 | + |
| 64 | +The preferred way to install this release is through one of the |
| 65 | +[milestone update-site][milestone-download]. |
| 66 | + |
| 67 | +This milestone is available for both [Scala 2.9][scala-29] and |
| 68 | +[Scala 2.10.0-RC5][scala-2.10-rc5] and it works with [Eclipse 3.7 (Indigo)][indigo] and |
| 69 | +[Eclipse 4.2 (Juno)][juno]. Make sure to use the update-site that matches the Eclipse |
| 70 | +version you are using, or the Scala IDE plugin will refuse to install. |
| 71 | + |
| 72 | +Furthermore, each update-site contains a number of additional plugins that you can install |
| 73 | +together with the Scala IDE: the [ScalaTest Eclipse plugin][scalatest] and the |
| 74 | +[Scala worksheet][worksheet] are already available! |
| 75 | + |
| 76 | +## Road to the final |
| 77 | + |
| 78 | +What's left to make this a final? Not much to be honest, we are confident this |
| 79 | +milestone release will make many of you happy. But, before making it a final, we still |
| 80 | +need to work on improving performances in both the Scala Debugger and the Scala Editor. |
| 81 | +This will be our focus for the next month: we plan to enter RC mode in early February. |
| 82 | + |
| 83 | +Don't miss the chance to give this milestone a spin, this is the perfect time to |
| 84 | +[report back issues][issues-tracker], if you want to see them fixed in time for the final |
| 85 | +release. |
| 86 | + |
| 87 | +## Welcoming Simon Schäfer |
| 88 | + |
| 89 | +We are happy to announce [Simon Schäfer][simon] as the latest addition to the |
| 90 | +[Scala IDE Team][scala-ide-team]. Simon joined the project just about six months ago, |
| 91 | +and we have been simply amazed by the high-quality contributions and his great positive |
| 92 | +attitude. |
| 93 | + |
| 94 | +Simon is a computer science student in Germany, at the |
| 95 | +[Karlsruhe Institute of Technology][kit], currently carrying out his 3rd semester bachelor. |
| 96 | +His main interest is compiler construction, and he started to contribute on the Scala |
| 97 | +IDE to gain experience on that topic. |
| 98 | + |
| 99 | +Wonder how he spends his free time? |
| 100 | + |
| 101 | +> Hmmm, programming? Scala is so much fun, there is no need to have another hobby. Ok, |
| 102 | +> I'm doing some martial arts, but that often feels to be harder work than working for |
| 103 | +> the Scala IDE. ;) |
| 104 | +
|
| 105 | +Simon, we are really glad to have you on the team. |
| 106 | + |
| 107 | +## Thanks |
| 108 | + |
| 109 | +We would like to take the opportunity to thank all contributors for the amazing work they |
| 110 | +have done to make this milestone possible. Special thanks go to Luc Bourlier, Chee Seng Chua, |
| 111 | +Mirco Dotta, Iulian Dragos, Ivan Kuraj, Michael Holzer, Eric Molitor, Simon Schäfer, Amir |
| 112 | +Shaikhha, Mirko Stocker, Matt Russell and Eugene Vigdorchik. |
| 113 | + |
| 114 | +#### Merry Christmas to everyone! |
