What's new in Qt SDK 1.2.1
Sep 25, 2013
- Provides updates that improve support for developing apps for the Nokia N9 smartphone, including:
- landscape and portrait orientation support in the Simulator.
- the Qt Quick Components used in the phone.
- three QEMU images: one each for PR1.0, PR1.1, and PR1.2.
New in Qt SDK 1.2 (Feb 3, 2012)
- Fixes for Qt Creator 2.4 in a new 2.4.1 patch update
- Qt 4.8 for desktops delivering Qt Quick 1.1, Qt platform abstraction, Qt WebKit 2.2, and threaded OpenGL. See Sinan’s blog post for more details.
- More Qt Mobility examples for Nokia N9 and Symbian devices
- Ability to specify network proxy setting in the SDK Maintenance Tool
- Update to the Symbian Complementary Package introducing Analyze Tool plugin and new CODA 1.0.6 installation package
- An update to Notifications API improving the end user experience and fixing issues in the Nokia N9 implementation of the API.
New in Qt SDK 1.1.4 (Dec 16, 2011)
- Qt Platform Abstraction (QPA):
- QPA restructures the GUI stack to enable easier porting of Qt to different windowing systems and devices. More info on: Lighthouse has grown up now.
- Threaded OpenGL support:
- Enables those of us that are not OpenGL-ninjas to render OpenGL from more than one thread concurrently. More info on: Threaded OpenGL in 4.8.
- Multithreaded HTTP:
- HTTP requests are now handled in a separate thread by default. This should make application guis smoother, as networking will no longer use the main event loop.
- Optimized file system access:
- The file system stack received some heavy lifting under the hood. The result is better I/O performance, achieved by reducing the number of system calls performed for I/O and by better use of cached data, when available. The improvements in performance can be seen across all platforms.
New in Qt SDK 1.1.3 (Sep 1, 2011)
- Qt Creator 2.3: Plenty of small improvements to improve the basic developer experience.
- Qt Simulator 1.2: in addition to a significant UI facelift, Qt Simulator 1.2 is introducing several new features: sensor simulation, simulation of NFC tags as well as gesture simulation.
- Notifications API 1.1 is introducing QML bindings and quality improvements.
- Qt 4.7.4 for desktop app developers.
- MeeGo 1.2 Harmattan beta: This version of the Harmattan target is built on the same software image that was used in the version released in June so does not introduce new features, but is required to be updated in order to continue developing MeeGo 1.2 Harmattan apps.
- Update to Symbian Complementary Package: important CODA update to expand the support also to the latest Symbian Belle devices. Note that the apps created with the beta level new target for Symbian Belle devices can not yet be submitted to OviStore.
- Update to Qt Quick Components for Symbian is not introducing functional changes.
New in Qt SDK 1.1 (May 4, 2011)
- Qt 4.7.3 (for Symbian, desktop, and simulator) and Qt Mobility 1.1.2 APIs.
- Qt Quick and Qt Creator 2.1 to provide a complete solution for UI development.
- Tools for Symbian, Maemo, and desktop apps, including the use of native APIs.
- Device binaries to enable apps created with the SDK to be run on Symbian devices.
New in Qt SDK 1.1 Beta (Mar 1, 2011)
- Included a significant amount of updates, namely:
- Qt 4.7.2 for Symbian ^1 and Symbian ^3
- Qt 4.7.2 for the Desktop
- Qt 4.7.2 for the Qt Simulator
- Qt Mobility 1.1.1 for Symbian^1, Symbian^3 and the Qt Simulator
- Qt Creator 2.1 final
- Qt Simulator 1.1 beta
- Updates to the Symbian Complementary package, providing the toolchain and build tools for the Symbian platforms
New in Qt SDK 1.1 Pre (Jan 21, 2011)
- The new Qt SDK 1.1 Technology Preview enables developers targeting desktop platforms to use the same setup, features and environment as developers targeting platforms. This eases the migration of desktop applications to mobile platforms (Have you heard about the “Qtest Mobile App Port” contest yet?).
- We have received lots of feedback from developers about the Symbian support level in the Nokia Qt SDK 1.0, specifically that it was not possible to use native APIs. In this case developers were asked to install the platform SDK, which required manual efforts. Now we have simplified this by refactoring the Symbian toolchain parts completely, allowing you to enable the usage of native APIs for Symbian^3 optionally. This can be done via the installer or the maintenance tool. Further features will be coming in this area in coming releases.
- In addition to this, supplementary packages have been added or received updates. The Nokia Qt SDK 1.0 already had the remote compiler integrated, which allows compilation of your project on a remotely hosted server. Several improvements made it into the latest version, also allowing compilation based on the updated Qt and Qt Mobility versions.
- The Notifications API describes a unified framework to create a connection to a server for receiving notifications, of course based on Qt. It is designed to use a minimum of data bandwidth as well as behave in a battery friendly manner, as is required by today’s smart phones. This feature is located in the experimental section of the SDK and will finalize soon.
- Concurrently we have fixed bugs we received during the time between the last release and this one for the Qt Simulator and the Installers.
