News: FileZilla - the free FTP solution

The FileZilla is open source software distributed free of charge under the terms of the GNU General Public License.
This software working with multi-platforms: Linux, Windows, MacOS.
Today I saw this month - December 2016 come with news about FileZilla software.
The good news from the official website is:

• Key file paths entered in the Site Manager are now saved to corresponding server entries in the transfer queue 
• MSW: Work around a bug in wxWidgets causing bad icons in the remote directory tree due to wxImageList::GetBitmap errorneously stripping the alpha channel from images 
• Allow relative paths and environment variables in the "Cache directory" setting. 
• Work around a bug in wxWidgets that has been causing a virtually infinite loop when deleting toolbar buttons 
•  Speed up icon scaling and cache scaled icons for faster subsequent loading. The cache directory can be changed through fzdefaults.xml using the "Cache directory" setting 
• OS X: Fixed icon display on high-DPI displays in a few more dialogs 
• Loading a corrupted layout.xml or search.xml no longer shows an error message, these files are now silently overwritten 
• MSW: Fixed a regression where UNC paths where not handled correctly as config location in fzdefaults.xml

News: A new image format for the Web.

The news comes from here.
WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster. WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller than comparable JPEG images at equivalent SSIM quality index. Lossless WebP supports transparency (also known as alpha channel) at a cost of just 22% additional bytes. For cases when lossy RGB compression is acceptable, lossy WebP also supports transparency, typically providing 3× smaller file sizes compared to PNG.

News: Google come with Neural Machine Translation.

In 10 years, Google Translate has gone from supporting just a few languages to 103, connecting strangers, reaching across language barriers and even helping people find love. At the start, we pioneered large-scale statistical machine translation, which uses statistical models to translate text. Today, we’re introducing the next step in making Google Translate even better: Neural Machine Translation.

News about the Firefox browser.

Come with download protection for a large number of executable file types on Windows, Mac and Linux.
The team improved performance for SDK extensions or extensions using the SDK module loader. This new version comes with Guarani (gn) locale.
One of the good features is WebM EME Support for Widevine on Windows and Mac but nothing about Encrypted WebM streams.
As you know the Encrypted WebM streams are encrypted at the block level with AES-128 CTR encryption.
The AES encryption takes way lesser processing time than decryption.
Last come with new two updates to keyboard shortcuts:
 - set a preference to have Ctrl+Tab cycle through tabs in recently used order;
 - view a page in Reader Mode by using Ctrl+Alt+R (command+alt+r on Mac);
