+Errors and Exceptions
+=====================
+
+
+Errors i18n
+-----------
+
+A general rule is to tranlate only errors that are shown to end users only. If
+it is a regular exception, debug screen etc. then message should not be translated.

+Yii version numbering
+=====================
+
+A.B.C
+
+A = For Yii2 it's always 2.
+B = Major version. Non-BC changes with upgrade instructions.
+C = BC changes and additions.
+
+A.B.CrcD
+
+This is when we want to release release candidate. D is the RC number. Starts with 1 and increments till we're getting a stable release with no critical bugs and BC incompatibility reports.
