Nuvola 4.9

Nuvola 4.9 was released on December 17th, 2017. It is mostly a maintenance release as most of energy is invested in the Chromium port of Nuvola and the development of other features has slowed down. The current status of this ambitious effort will be described in a separate announcement.

Note that Nuvola versioning has changed after Nuvola 3.1.3 and version 3.1.x became 4.x (3 + 1 = 4).

Under the hood

  • WebKitGTK >= 2.18.0 is required.
  • If Nuvola is told that WebKitGTK supports MSE, it checks whether it is so and aborts otherwise. Don't use --webkitgtk-supports-mse if it isn't true.
  • Fixed various memory leaks.
  • Ongoing optimizations to replace synchronous IPC calls with asynchronous variants.
  • ValaCEF project has been created to provide Nuvola with Vala bindings for Chromium Embedded Framework (CEF).
