+------------------
+
+* We now use PSR-4 for the directory structure. This means that everything

+* Expanded the vobject cli tool validation output to make it easier to find
+  issues.

+
+
+3.2.2 (2014-05-07)

+  properties such as N, ADR, ORG and CATEGORIES.

+  into individual objects (thanks @DominikTO and @armin-hackmann).
+* Added: VFREEBUSY component, which allows easily checking wether timeslots are
+  available.
+* Added: The Reader class now has a 'FORGIVING' option, which allows it to parse
+  properties with incorrect characters in the name (at this time, it just allows
+  underscores).
+* Added: Also added the 'IGNORE_INVALID_LINES' option, to completely disregard
+  any invalid lines.
+* Fixed: A bug in Windows timezone-id mappings for times created in Greenlands
+  timezone (sorry Greenlanders! I do care!).
+* Fixed: DTEND was not generated correctly for VFREEBUSY reports.
+* Fixed: Parser is at least 25% faster with real-world data.
+
+
+2.0.0 (2012-08-08)
+------------------
+
+* VObject is now a separate project from SabreDAV. See the SabreDAV changelog
+  for version information before 2.0.
+* New: VObject library now uses PHP 5.3 namespaces.
