[ANN] Kivy 1.5.0 released

[Mathieu Virbel]

Hi everyone,

We are pleased to announce Kivy 1.5.0.

Kivy is a full featured framework for creating novel and performant
user interfaces, such as multitouch applications, under the LGPL 3
license. The framework works on Windows, OSX, Linux, Android and iOS.
All downloads are available on the website:

http://kivy.org

What's new in this release?

- DPI support improvements. We now have a kivy.metrics module with
various converters. We removed the invalid calculation in the
Label.font_size for simulating DPI. It was something we had from
the first Kivy release, and must now be removed to correctly
handle DPI. All your labels will be 33% smaller now, if you
specified font_size in pixels (or without units). All our widget
dimensions are now using DPI-related units.

The preferred way to specify font_size value is to use "sp" units:
Scale-independent Pixels. To specify any other dimension use "dp"
units: Device-independent Pixels.

Both notations came from the Android world, and are explained in
the kivy.metrics module: http://kivy.org/docs/api-kivy.metrics.html.

- New "screen" module. With this module, you can simulate how your app would
render on different devices like::

python main.py -m screen:droid2
python main.py -m screen:onex,portrait
python main.py -m screen:ipad

- New ListView widget. This widget provides a scrollable/pannable viewport
that will load and display only the item instances that are clipped in the
current view. This way, you can display thousands of items, minimizing
UI lag.

This isn't just a simple widget; it has a separation between the View and
the data source through use of adapters that perform creation and
management of list item views. We have adapters for different kind of data
sources. ListView also supports selection (single, multiple), configurable
views (via kv template or custom widget), and custom data converters, which
convert source data items to arguments for their list item widgets.

Check the extensive documentation at:

http://kivy.org/docs/api-kivy.uix.listview.html

- New CodeInput widget. This is a TextInput that support syntax
coloration, via pygments.

- iOS branch is merged to master. Now iOS will follow master
revision, same as python-for-android.

- PPA for Ubuntu and COBS packages for Meego are now available!

As usual, any issues / features should be reported at:

http://github.com/kivy/kivy/issues

Thanks all,

great upgrade experience here on Mac OSX Lion (10.7.5) from kivy 1.4.1:

I just moved the Kivy.app from the Kivy-1.5.0-osx.dmg to my Applications folder replacing the former version.

Clicking its icon in Launchpad resulted in upgrading the /usr/local/bin/kivy command as well, which had been created using the 'Make Symlinks' script when 1.4.1 got installed. (The /usr/local/bin/kivy command now uses python2.7 instead of python2.6).

One minor thingie: kivy reports it's version v1.5.1-dev already :-)

Oops, my bad.

It's not a big deal about 1.5.1-dev, but i'll redo and reupload the
correct package with 1.5.0 version.

Yes, i completely forgot to announce that now, OSX version is based on
2.7 system python. It also include an updated GStreamer version that
works with http/h264 streams, and pygments library.

Can you elaborate on the http/h264 streams?

What has been fixed?

It wasn't working on OSX, now it's working. So just put a http:// with a
h264 stream in the Video or VideoPlayer as a source, it will work :)
