Background When attempting to use the v0.2.14 release, @pandadefi discovered an issue using the "@nonreentrant" decorator. Impact Reentrancy protection storage slots get allocated to the same slots as storage variables, leading to the corruption of storage variables when using the "@nonreentrant" decorator. Patches This issue was fixed in v0.2.15 in #2391, #2379 Workarounds Don't use the "@nonreentrant" decorator in these versions.
