Opera 19 has just received another update, so in case you’re running the app right now, make sure you get the fresh build as soon as possible.
The parent company has only recently updated the download links, so there are no details regarding what’s new in this build for the time being.
Opera Web Browser 19.0.1326.63 is probably supposed to fix bugs and address a number of performance glitches found in the previous versions, so it’s mandatory to deploy the update especially if you’ve been experiencing issues with the older installations.
As usual, Opera comes with a built-in update engine, so the new version is automatically downloaded and installed on both Windows and Mac OS X computers.
