ScyllaDB Open Source Release 3.0.7

ScyllaDB Open Source 3.0.7 is a bugfix release within the ScyllaDB Open Source 3.0 stable branch, offering backward compatibility and support for rolling upgrades. This release addresses specific issues such as incorrect handling of empty counters in the "mc" SSTable file format, rare conditions causing missing rows during range scans, performance impacts due to a "use after free" scenario in the TimeWindowCompactionStrategy, and latency spikes caused by stalls when calculating the Heat Weighted Load Balancing (HWLB) for a large number of tables. Users are encouraged to report any problems encountered with this version.
