MMEdit 5 on Ubuntu 10.25

Does anyone know if MMEdit 5 is still being maintained? I used it all the time on my Ubuntu desktop and it was really useful especially with the communication app to quickly upload my updated code for testing on my PicoCalc, but at one point I needed to upgrade my Ubuntu from 04.25 to 10.25 and now it no longer works because of missing Qt5 libraries that are no longer available in 10.25.

I haven’t seen any discussion on the MMEdit page and it’s a huge bummer.
