Final or stable version of Opera 43 based on Chromium 56 has been released for Windows, Mac and Linux platforms and available for download from Opera website. The new version promises even faster page loading when compared with previous version, thanks to Instant Page loading and Profile Guided Optimization (PGO).

As we’ve told when Opera version 43 was in developer stream version that speculative prerenderer in address bar makes it possible to load pages in the background by predicting what you’re going to type in the address bar.

Krystian Kolondra. EVP Desktop @ Opera says in a blog post about how instant page loading works: ” Instant page loading is a technology that predicts which website you’re typing the address for. Once recognized, it begins loading the site in the background even before you hit enter.”

“Instant page loading becomes smarter over time by learning which URL inputs led to a specific website.” He added.
