+Version 0.5.0, Release Date: 2014-10-06
+---------------------------------------
+
+ This release focuses on simplifications and more flexibility in the frontend
+ and the query language. Most of those changes are not backward-compatible
+ but easy client implementations.
+
+ * sysdb:
+ - Include priority when printing log messages.
+ - Fixed handling of empty queries.
+ * store:
+ - When serializing the entire store (LIST command), return an array of
+ host objects (rather than wrapping it into another object).
+ - Fixed JSON format of time-series data.
+ - Fixed error checks of invalid compare expressions and reject them.
+ - Fixed lookups by back-end name.
+ - Added support for comparing attributes with different types by
+ comparing their string values.
+ * frontend:
+ - Clarified details about asynchronous messages and authentication
+ options and made client implementation more robust.
+ - Introduced a new message type encoding the JSON serialized response of
+ a query and its data type.
+ - Include the priority in log messages.
+ - Include object types in FETCH, LIST, and LOOKUP messages.
+ - Added support for including services and metrics in LIST responses and
+ skip hosts without the respective children.
+ * query language:
+ - Added support for services and metrics to LIST command.
+ - Changed syntax for attribute lookup to 'attributes[<name>]'.
+ - Changed syntax for accessing queryable fields to '.<field>'.
+ * utils:
+ - strbuf: Improved memory management.
