Yes, it has been fixed. But Ubuntu 20.04 doesn't 'see' anything modern enough to download/update.
Ironically, with the [faulty] compiler I'm using,
my_uint8_t / 2
generates the code I want (single 8-bit shift),
Whilst my "better than dividing by 2 code" I used back in the 80's,
my_uint8_t >> 1
generates more (and unnecessary) assembler code.
