This is a regular minor release, thus it not only includes many bugfixes but also many new features and improvements.

• With qooxdoo being a universal JavaScript framework not only for typical rich internet applications, but also for low-level webapps (think jQuery) or GUI-less server-side solutions (think node.js), it was quite a natural step to embrace the mobile world as well: Now you can leverage qooxdoo's object-oriented programming model and its powerful toolchain to also create mobile apps for smartphones. With its dedicated mobile widget set you can create multi-platform mobile apps (currently for Android and iOS devices), while sharing code and app logic with a more typical desktop-oriented qooxdoo app. A mobile variant of the feedreader demo for instance reuses a common layer based on data binding, while a mobile showcase highlights most of the existing mobile widgets and features. As with most of the mobile world nowadays also qooxdoo's mobile enhancement is still experimental and work in progress. We will keep you up-to-date and invite everybody to try it out, get familiar with its current state and contribute back.

• The set of virtual widgets, which can easily handle even huge data sets, has been completed even further. The virtual List, introduced as experimental last time, is now meant for production. In addition both a new virtual SelectBox and a virtual ComboBox are ready to be used. And yet another thing: a new experimental virtual Tree is also part of the package.

• Introduced new "Simple" theme, which leverages modern browsers' new theming capabilities, specifically CSS3, not requiring images for gradients, rounded borders or shadows. The "Modern" default theme has been updated to also take advantage of CSS3 in newer browsers. Two different fallback strategies for legacy browsers have been implemented in those themes: while Modern falls back to the previous image-based theming, the Simple theme looks a bit less shiny but still great in browsers like IE6 and others.

• Talking of images: there is now full support for base64 images, which get included via "data:" urls as inline resources in today's browsers. The toolchain greatly supports you in doing so in quite a transparent way, i.e. with a proper fallback in older browsers.

• With that many enhancements in theming, it made sense to create a new demo app that showcases most - if not all - of the widgets and themes that ship with the framework: The new Widget browser complements the existing demo apps like Showcase, Demobrowser or the interactive Playground.

• With the large variety of classical browsers, even browser-based runtimes, on desktop as on mobile, there's much debate about feature detection. Besides all religious beliefs, in practical life every developer should be able to decide to what extent an app should take advantage of build-time and/or run-time branching. qooxdoo supports both in an elegant and powerful way: with the new "Environment" implementation you can go from a pure feature detection at run-time to optimized feature-specific builds. It also unifies and replaces qooxdoo's previous layers for feature detection, settings and variants.

• Apparently a general topic of this release is the enhanced support for modern browsers. Of course, this release comes with full support for the latest browsers IE9 and Firefox 4. It also comes with extended HTML5 support, including first experimental wrappers to Audio, Video, Geolocation, Web Storage, Web Workers.

• The new Testrunner, included as a preview in the last release, has replaced the previous one. It is a prominent part of qooxdoo's built-in unit testing solution. The Testrunner is now elegantly based on data binding, and allows for different UIs: while it still comes with the traditional rich user interface, it also supports a lightweight HTML view and even a pure browser console view. Advanced developers will also appreciate the possibilities to use spies, stubs and mocks within their unit tests.

• Another experimental tool of the previous release is now meant to be put into production: The Simulator is qooxdoo's built-in solution for automated GUI tests using Selenium. All infrastructure now ships with the SDK, you only need to download Rhino and Selenium RC.

• The comprehensive toolchain has been made even more robust, e.g. when developing apps against multiple framework versions, for varying platform setups, with a more complete dependency analysis or when creating localized apps. Besides spearheading or complementing new enhancements like feature-specific builds or base64 images, it introduces a handy source-hybrid target, for generating an app, which combines the ease of debugging an app's source version with near the speed of loading its build version.

See this detailed list of issues resolved for qooxdoo 1.4, which includes the fixes of the accompanying 1.3.1 patch release. A detailed list for those issues that were resolved for 1.4 exclusively, see here.

Being a regular release with many additional and improved features, there are some migration steps needed for upgrading your apps from the previous 1.3.x releases. After the semiautomatic migration steps supported by the toolchain, you will most likely notice a number of typical deprecation warnings in the development version of your apps ("source"), while that shouldn't affect the production version of your app ("build"). Nevertheless you should get rid of those runtime warnings altogether by adjusting the places in code you are pointed to.

If you need a bugfix-only drop-in replacement, you might want to check-out qooxdoo 1.3.1, the corresponding patch release.

• Many improvements to API consistency, documentation and usability of the Simulator. (#4702)

• Added new skeleton as a starting point for developing mobile apps. (#4793)

• Support for base64 images; base64-based combined images can now be created and used in place of traditional combined images, and are then applied e.g. as data: URLs.
• The generator now better supports the use of alternate Python interpreters in subprocesses by using Python's sys.executable instead of hard-wiring the interpreter name. This is also available in configuration files through the PYTHON_CMD macro (see further). (#4479)
• The default CACHE macro is now version-dependent (e.g. /tmp/qx1.4/cache); this better supports side-by-side installations of different qooxdoo versions, which no longer clear each others cache objects.

• A new default job, source-hybrid, has been introduced; it collects the unaltered source code of classes into common .js files, thus combining the ease of debugging of a source version with the near speed of app loading of a build version.
• Generation of parts has been strongly improved, making package merging more robust and enforcing additional constraints on the parts configuration that could otherwise lead to non-working packages being generated. (#4491, #4576)
• Recursive method dependency analysis has been extended to include file-level method calls, making dependency analysis more complete. Analyzing a method recursively is now indicated by a _ (underscore) in the generator console output. (#1455)

• New default config macro PYTHON_CMD exposes the Python executable with which the generator was started (aka sys.executable; usable e.g. in shell config keys).
• Removed support for non-dependent excludes in exclude key which are completely covered by normal exclude expressions, for better code efficiency.
• New job-level configuration key environment, which unifies and supersedes the deprecated keys settings and variants. Environment settings can serve as a simple key:value store, can trigger variant builds by the generator, and allow compile-time code optimization. Supported values are all simple JSON values (string, number, boolean, 'null'), or lists thereof. If you use both variants and environment with same keys in your job configs, the variants settings will take precedence.

• Upgraded CLDR data from unicode.org to version 1.9 (of 2010/12/01).
