Greasy Fork

• updated dependency factory function call name

• removed async requirement for factory function, since dependency is now static webhook code

• updated example code with correct tested code

• updated @require URL again due to new dependency version, which will have no effect other than FYI, but it's technically a code change

• updated @require URL to new version of dependency (which changes nothing, since only the script @requires are used)
• removed @grants that were no longer used
• clarified metadata required by scripts using this library
• updated example code

• minor metadata edit

• made constructor construct private members properly

• removed unworkable scheme for storing class

• learned that when a @required script is updated, the caller's @require metadata needs updating too, or else the caller keeps using the old version of the dependency

• @granted all privileges needed by dependency

• addressed bug in code that computes key under which the returned class is stored

Added @homepageURL and @supportURL to script metadata

• included license
