At the moment, no. Beyond just fixing problems I've found, for the last year I've been doing a lot of haphazard development inside of Sprite itself, so "fixes to bugs in released Sprite" are intermingled with "features I've added". The bigger problem is that getting data in/out of Sprite is ... harder than you'd imagine.

I am hoping to make a big writeup "soon", since there's a lot of interesting information about Sprite that's mostly been lost to time, where Sprite is mostly remembered as having "process migration" and "LFS". Meanwhile, it's mostly forgotten that Sprite was (apparently) one of the first OSes to adopt a mostly-GNU userland, had a modern event-loop style abstraction in C for handling I/O and timers (Fs_Dispatch), had a userspace filesystem abstraction akin to FUSE (PFS), implemented a PTY-like system entirely in userspace (the Td* functions in libc), and overcommitted memory by default.
