Release a new version, could be based on patch

My CI builds are breaking again too many times for the same error - TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'. I reckon you had fixed that error somehow but there hasn't been a new release since. Could you possibly release a new version on pip(that's where we install meson from) with a patch upgrade 0.34.1 if you're not thinking of releasing a major version soon.
