Stella release 4.7.1 for Linux, MacOS X and Windows is now available.

• Improved TV 'jitter' emulation; the recovery time can now be spread over multiple frame, to simulate a real TV taking multiple frames to recover. Related to this, added new commandline argument 'tv.jitter_recovery' to set the recovery time. Finally, enabling the jitter effect and the recovery time are now accessible through the UI. Special thanks to SpiceWare of AtariAge for the initial idea and implementation.
• Fixed bug with 'Medieval Mayhem' ROMs; the paddle range was set too low, and as a result the number of players couldn't be selected.
• Fixed bug when using more than two input controllers with the same name; each controller after the second one was named the same as the second one. This caused the joystick mappings to be lost, since there was only information about two controllers being saved.
• Indirectly fixed issues with Stelladaptor/2600-daptor devices and paddles having too large of a deadzone in Linux. Currently, this involves running an external application to set the deadzone, since SDL2 does not yet expose this information. The program is called 'evdev-joystick', and will be released separately from Stella.
• Updated internal ROM properties database to ROM-Hunter version 11 (thanks go to RomHunter for his tireless research in this area). Related to this, updated the snapshot collection.
