ares: vanhemmat versiot ja versiohistoria

ares v148 has now been released.
This release includes big improvements to a number of ares cores. Highlights include rewrites to the N64 CPU & RSP JITs resulting in significant performance gains across the N64 library, additional implementation & accuracy improvements to the PlayStation core, fixes to the GBA core, and support for the Famicom data recorder & Dendy.
Additionally, there have been many updates to the core ares application across all platforms. Per-core input configuration has been added, updated video, audio, & input drivers are available, bug fixes, additional options have been added, and core dependencies have been updated.
Since v147, 20 contributors have created 300 commits to the ares codebase.
As always, if you wish to see the full changelog in a per-commit format along with their authors, you can do so on GitHub here.
