Qt Creator version 2.2 contains bug fixes and new features.

The most important changes are listed in this document. For a complete

list of changes, see the Git log for the Qt Creator sources that

you can check out from the public Git repository. For example:

git clone git://gitorious.org/qt-creator/qt-creator.git

git log --cherry-pick --pretty=oneline origin/2.1...origin/2.2

General

   * Add support for running user defined external tools (Tools > External)

   * Move tool chain definitions out of Qt versions:

      * You can now define tool chains in Tools > Options > Tool Chains

      * Qt Creator now supports more than one instance of a tool chain

   * Add support for customizing MIME types by editing patterns and

     magic headers

   * Integrate the memcheck tool from Valgrind for Linux and Mac OS X

   * Create the infrastructure to set up "soft dependencies" between plugins

   * Add the qtpromaker tool that has the same functionality as

     "qmake -project", but is much faster. It provides a way to easily set up

     dummy .pro files that you need to quickly inspect and navigate "alien"

     codebases with Qt Creator

   * Document Qt Creator coding style

Editing

   * Add an Inkpot color scheme

   * Add UTF-8 BOM support

   * Move the Open in External Editor item to Tools > External > Text

   * Add the Expand/Collapse All context menu item to the Outline pane

   * Add support for user-defined macros (contributed by Nicolas Arnaud-Cormos)

   * Add a snippet editor with syntax highlighting, indentation, and basic

     auto-completion for C++ and QML

   * Add GLSL support with:

     - Syntax checking

     - Highlighting

     - Code completion

   * Binary editor:

     - Visualize data differences after updates

     - Fix selection if cursor is left of anchor

     - Allow copying also if selection is "backwards"

     - Do not draw blinking cursor when there is a selection

     FakeVim:

     - Implement Ctrl-N/Ctrl-P

     - Implement 's' in visual block mode

     - Fix Alt-Gr handling on Windows

     - Handle more Ctrl-W + <x> commands

Managing Projects

   * Improve the robustness of qmake project support against syntax errors

   * Change the handling of command line arguments of processes that are

     started from build and run configurations:

     - Argument lists use native shell syntax; this affects quoting and

       environment variable expansion most

     - The SOURCEDIR and BUILDDIR environment variables were replaced

       with %{sourceDir} and %{buildDir} variables

     - This affects working directories and executable paths as well

   * Support syntax highlighting and completion for qmake project files

   * CMake: Add UI completion, changes in .ui files are picked up without

     a rebuild

   * Specify text editor behavior settings per project

   * New project and file wizards:

     - Support new keywords %MONTH% and %DAY% for C++ template file

     - Add wizards for creating OpenGL fragment and vertex shaders

     - Add a wizard for creating HTML5 based applications

     - Add a wizard for creating JavaScript files, QTCREATORBUG-3070

Debugging

   * Rewrite debugging engine using the Microsoft Console Debugger (CDB)

     for debugging executables built with Microsoft Visual Studio,

     resulting in significant speed-up and better display of data

     types, supporting both 32-bit and 64-bit versions of the

     Debugging Tools for Windows

     QBasicAtomicPointer, bit fields, boost::shared_ptr (GDB only)

   * Improve dumpers for QRegion, QVariant (custom types), QSharedPointer,

     QMultiMap (QTCREATORBUG-3122), QObject, QWeakPointer

   * Qt Quick Application: Allow debugging also in release builds, improve error

     diagnostics

   * GUI cosmetics in JS debugger: Show stack frame level, only valid

     line numbers in stack view, do not show function code, show dummy

     child entry for empty arrays
