<p dir="ltr">In Erlang, two and only two versions of the same module can coexist in the run time system (an old version and a new version). Processes running the old version of the code will keep running that version (even if you load a new version of the module) until they make a fully qualified call to the module itself (I.e. M:F(A)). If you add a third version of the code in the system (e.g. you load a module twice) the "very old" version gets purged and those processes executing the obsolete version get killed. You can also use code:purge and code:soft_purge to "force" this behaviour. Look at the "code" module for more options.</p>
