 ver. 0.10.2-dev-1 (2017/??/??) - development edition

+### Incompatibility list:
+* The configuration for multiport jails using banaction `pf` can be incompatible after upgrade, if

 ### Fixes
+* action.d/pf.conf: 
+  - fixed syntax error in achnor definition (documentation, see gh-1919);
+  - enclose ports in braces for multiport jails (see gh-1925);
