Keep version aligned with GNOME
3.34 was released 3 weeks ago at the same time as GNOME 3.36 (presumably because there was no update with GNOME 3.34?), which is confusing.
It would make more sense to keep the version aligned with the nearest GNOME release, so make the next one 3.38 (or 3.40 if released with GNOME 3.40 etc.)
