ScyllaDB release: version 1.2.5

ScyllaDB 1.2.5, a bugfix release of the ScyllaDB 1.2 stable branch, has been announced by the ScyllaDB team, bringing backward compatibility and support for rolling upgrades. This release addresses various issues, including the inability of scylla.yaml to read initial_token strings with spaces and unexpected aborts when querying with contradicting clustering column restrictions, which are now fixed to return an empty result. Contributions from several developers, such as Paweł Dziepak and Tomasz Grabiec, have led to improvements like ignoring spaces in the initial_token list and fixing use-after-free issues involving bound_views. The release also provides guidance for upgrading from 1.1.x to 1.2.y and encourages reporting problems and contributing to ScyllaDB development.
