Opera, the alternative web browser from Norway, adds several new features in version 50, which was released earlier in January.

Perhaps the most interesting new feature detects and blocks covert cryptocurrency mining, a new threat that sneakily uses your computer’s resources to make money for the perpetrators.

Other changes in this release include:

• Chromecast support
• VR Player enhancements, including Oculus Rift support
• new: save web pages as PDF files
• improvements to the tab context menu
• currency and unit converter improvements
• better crash protection
• enhancements to the built-in VPN service

You can peruse the Opera 50 change log for additional details. Keep in mind that the log shows all changes to Opera 50 from its origin as a developer release in September 2017, through its beta stages, to its official release in early 2018.
