A special release for legacy systems

This is a special release only for Windows for legacy systems such as Windows XP and Vista. This release includes Chromium 49.0.2623.110 which is the latest Chromium version that supports WinXP/Vista.

Installation

You can install pypi/cefpython3 package using pip tool. You can also download packages for offline installation available on this GitHub Release page. Command to install with pip:

pip --no-cache-dir install cefpython3==49.0

Please note that if you were previously installing cefpython3 package it is required to use the --no-cache-dir flag, otherwise pip will end up with error message No matching distribution found for cefpython3==49.0. This happens because 49.0 release occured after 57.0 and 66.0 releases.

Changes and notes for this release

• Update to Chromium 49.0.2623.110 (#460)
• Support for Windows XP SP3 or later (Vista, 7, 8, 10). Chromium requires at least SP3 on WinXP.
• Support for Python 2.7 and 3.4. Python 3.4 is the last version of Python that supports Windows XP.
• There were multiple changes in upstream CEF that are backward incompatible and thus require modifications in your app code. See the Migration Guide document for details.
• Documentation is available in the docs/ directory in the cefpython49-winxp branch
• API reference is available in the api/ directory in the cefpython49-winxp branch
• Examples that were tested and do work fine: hello_world.py, gtk2.py, qt.py pyqt4, qt.py pyside, tutorial.py, screenshot.py, tkinter_.py and wxpython.py (all except gtk3.py which wasn't tested)
• Add snippets in the examples/snippets/ directory
• Update screenshot.py example to pass switches to disable GPU acceleration which is not supported in OSR mode and can cause issues if enabled. Also pass additional Chromium switches to enhance performance. (#463)
• Do not call WindowUtils.OnSize function which can sometimes cause app hanging during window resize event. Call instead the new WindowUtils.UpdateBrowserSize function. Except when you use the pywin32.py example, in such case WindowUtils.OnSize must be called. (#463)
• Known issue: qt.py pyqt4 and gtk2.py examples can sometimes hang app during window resize (rare, but happens from time to time)
• Update unit tests and add OSR unit test
• The cefpython57 branch was used as a base for the cefpython49-winxp branch and thus it comes with all the new build tools, fixes and new examples
• Upstream CEF prebuilt binaries for this release are available in release tagged v49-upstream.

Known issues

• Enter key doesn't work in Developer Tools window in the wxpython.py example. Enter key works fine when running the hello_world.py example, so this is only an issue with wxPython. To resolve it create either a devtools.py script or use remote debugging and open DevTools in a Google Chrome browser. The devtools.py script is basically a hello_world.py example with one change to url, set it to http://127.0.0.1:1234/. In your wxpython app set ApplicationSettings.remote_debugging_port to 1234 and open DevTools popup by executing subprocess.Popen([sys.executable, "devtools.py"]). The "Developer Tools" from mouse context menu won't work, however you can implement a custom context menu in javascript.

With these upstream CEF prebuilt binaries and libraries you can build CEF Python from sources in less than 10 minutes. See the Build instructions document for details.

Prebult binaries and libraries were created according to build instructions with the automate.py script by running the automate.py --prebuilt-cef command.

Notes:

• The cefclient and cefsimple sample applications require Vista or later. It should be possible to build these to support XP as well, but it would require modifications to CEF's cmake/ninja configuration in the cef_binary archives. If there are still issues on XP then see upstream Issue #1787.
• The cef_binary archives contain only Release mode binaries
• CEF binaries for v49 (branch 2623) are not available anymore in upstream CEF (neither cefbuilds nor Spotify), as this is an old unsuported branch

Installation

You can install pypi/cefpython3 package using pip tool. On Linux pip 8.1+ is required. You can also download packages for offline installation that are attached to this GitHub release. Command to install with pip:

pip install cefpython3==66.0

Changes and notes for this release

• Update to CEF/Chromium 66.0.3359.181. (#403) See also the "Notable changes in upstream CEF" section further down on this release page.

• Add easy to understand code snippets in the "examples/snippets/" directory. These snippets show how to use various CEF features:
  • javascript_bindings.py - Communicate between Python and Javascript asynchronously using inter-process messaging with the use of Javascript Bindings.

Master branch is currently v66. There is no cefpython66 branch at the moment.

With these upstream CEF prebuilt binaries and libraries you can build CEF Python from sources in less than 10 minutes. See the Build instructions document for details.

Built according to build instructions with the automate.py script. On Windows and Mac binaries from Spotify Automated Builds ("Standard distribution") were used and then ran automate.py --prebuilt-cef. On Linux CEF was build from sources by running automate.py --build-cef.

LINUX NOTE: Linux binaries were built on Ubuntu 14.04 64-bit. These binaries contain libcef.so with minimal symbols so that you can debug CEF with gdb and get a meaningful stack trace. Currently cefpython v54-v66 and later distribution packages on PyPI and on GH releases ship a stripped version of libcef.so with no symbols at all (Issue #262). Download archive from this release and switch libcef.so in your already installed package to allow for debugging CEF.

Built according to docs/Build-instructions.md with the tools/automate.py script.

NOTE for Linux: Linux binaries were built on Ubuntu 14.04 64-bit. These binaries contain libcef.so with minimal symbols so that you can debug CEF with gdb and get a meaningful stack trace. Currently cefpython v54 and later distribution packages on PyPI and on GH releases ship a stripped version of libcef.so with no symbols at all (Issue #262). Download archive from this release and switch libcef.so in your already installed package to allow for debugging CEF.
