SNES:
- Add FastROM option for SuperFX (srg320).

Downloader:
- Version 1.8 released.
- Introduced a free space check before installing files. The minimum free space can be adjusted at your own risk using the minimum_system_free_space_mb and minimum_external_free_space_mb options in downloader.ini. More information is available in the README file.
- Added the capability to back up and restore system files during Linux updates (wizzo). Files included so far: /etc/hostname, /etc/hosts, /etc/network/interfaces, /etc/resolv.conf, /etc/dhcpcd.conf, /etc/fstab
- Introduced a new test bench to realistically measure system performance during development.
- Deprecated the base_path option. While it is still used internally, it has been removed from the README and is no longer intended for user customization.
- Implemented file system caching that improves the speed of short runs (runs with no updates) by around 3x when the system has been recently initialized.
- Databases are now processed in parallel during file installations, increasing overall speed. This results in a 5-15% speed improvement with stable Ethernet connections, and I've measured up to a 50% speed improvement on less reliable Wi-Fi connections.
- Introduced a job system to manage concurrency. Currently, it is used for fetching, installing, and validating files.
- Reworked the build script to reduce the bundle size, slightly speeding up the time the launcher takes to download it during each Downloader run.
- Local storage is now saved without compression, saving around a second in all runs but using slightly more system space (typically less than 5 MB).
- Improved handling of file and folder creation errors.
- Fixed a bug affecting non-Keep-Alive connections.
- Fixed a bug that occurred when trying to hash a corrupted file.
- Fixed a bug affecting the download filters feature under certain conditions.
- Reimplemented the debug script in Python, adding additional options and features. This is useful primarily for development.
- Various other fixes and improvements.

Distribution repo:
- Improved download_distribution.py utility to also work with branches and subpaths.
- Added “mister_firmware” as filter term for matching just the MiSTer firmware file.
- Fixed a bug on db_operator.py that caused the utility to not handle uppercase file hashes correctly.
- Added a way to easily add extra single files to the distribution under the “user-content-file” category.
- Moved Genesis Cheats to MegaDrive folder. Adding SMS cheats to the MegaDrive folder too.
