+Semantic Changes (TAKE NOTE):
+
+Channel keys and passwords (see the "oplevels" enhancement below)
+listed in a JOIN are now only checked against the corresponding
+channel. In ircu2.10.11, "JOIN #a,#b key" would attempt to use "key"
+as the key for both #a and #b. ircu2.10.12 will only attempt to use
+it as the key for #a. ircu2.10.12's behavior matches that documented
+in RFC 1459.
