Although Microsoft Edge does not dominate the browser market, the offspring of the Redmond corporation has some exclusive features that make it a worthy competitor.

The Document Foundation announced the cessation of the formation of 32-bit binary builds of LibreOffice for Linux. The change will take effect starting with version 6.3, which is expected on August 7.
