Patches
Users are required to update to version 1.2.1 or newer.
Versions older than 1.2.1 have been yanked from crates.io. This was believed to have already been done at the time of the 1.2.1 release, but upon double checking now they were found to still be available, so has been done now (22nd October 2020).
