- License was intended to be GPLv3 per earlier commit of GPLv3 LICENSE FILE - This is confirmed by the inclusion of libraries that are incompatible with GPLv2 - This is also confirmed by KLS and the agreement of KLS's predecessors - Added GPLv3 license headers to the compilable source files - Removed Folly licensing in strings.h since the string functions do not match the Folly functions and are standard functions - this must have been left over from previous implementations - Removed individual contributor license headers since the project has been under the "developer" mantle for many years - Removed comments on files that were previously automatically generated since they've been manually modified multiple times and there are no automatic scripts referencing them (removed in 2023)
