Running the miner under python >= 3.12 causes a SyntaxWarning. The problem was
already present in previous versions, but it only triggered a
DeprecationWarning, which was not shown by default.
The change is useful for future-proofing the code base, since future python
versions will start to exit with a runtime exception (see the reference given
later).
Command to see the warning at runtime under python3.11 (DeprecationWarning,
needs "-Walways"):
$ python3.11 -Walways ./contrib/signet/miner
<BASE>/contrib/signet/miner:33: DeprecationWarning: invalid escape sequence '\d'
RE_MULTIMINER = re.compile("^(\d+)(-(\d+))?/(\d+)$")

Command to see the warning at runtime under python3.12 (SyntaxWarning, no
modifiers needed):
$ python3.12 ./contrib/signet/miner
<BASE>/contrib/signet/miner:33: SyntaxWarning: invalid escape sequence '\d'
RE_MULTIMINER = re.compile("^(\d+)(-(\d+))?/(\d+)$")

Reference ( https://docs.python.org/3.8/library/re.html ):
Regular expressions use the backslash character ('\') [...]. This collides
with Python’s usage of the same character for the same purpose in string
literals; [...]
Also, please note that any invalid escape sequences in Python’s usage of the
backslash in string literals now generate a DeprecationWarning and in the
future this will become a SyntaxError.
The solution is to use Python’s raw string notation for regular expression
patterns;
