Recorded objects and recorded throughput telemetries were always disabled for snapshots
Command line export: -liveness option was not respected for RecordedObjectsView
Mac OS X: Applet profiling instructions given by the wizard were wrong

Much lower memory overhead on the profiled JVM when taking a heap snapshot
Much lower memory overhead when opening snapshots with heap dumps or HPROF snapshots
Much lower memory overhead when opening snapshots with lots of CPU data (for snapshots saved with 5.2+)

Trigger enhancements
Added "JVM startup" and "JVM exit" triggers
Enabling and disabling triggers from the GUI and the API
Trigger groups that can be enabled or disabled together
Trigger action and API for controlling the call tracer
"Trigger heap dump" trigger action now also works in online mode

Threads were not sorted alphabetically in the thread selector of the CPU views
Bookmarks created with the API were sometimes not transmitted immediately
When modifying trigger settings, the config file was not updated after closing the session settings dialog

Remote integration wizard: If the installation directory of JProfiler on the remote machine was specified with a trailing file separator, the modification instructions were wrong or the integration failed.
Call tree view: "Show all" action after "Set as root" action did not always work correctly.
Web start sessions: The chooser button for JNLP URLs in the application settings did not show any results from a Java 6 installation (new cache format).
Web start sessions did not work with Java 1.6.0 update 10 and higher
"Hot spots" view: For hot spot types other than methods, average times and invocation counts were not displayed if "Sampling" was selected as the method call recording type, even though this information is always available.
