Call graph: Outgoing calls are now always from the right side of the node
Call graph: Opening outgoing calls first opens the important nodes as configured in the view settings, only on the second click it opens all nodes
Clicking on edges in graphs jumps to the target node if invisible, Ctrl/Cmd Click jumps to the origin node

Ctrl/Cmd C in graphs copies text from the selected node or the tool tip text if no nodes are selected
Quick search in graphs
Undo/Redo actions for all changes to graphs
Call tree analysis for collapsing recursions

Recording actions for probe events

Retina support on Mac OS X
"Set root" action in call tree now limits data in hot spots view and call graph
Support for MongoDB driver 3.x with both old and new API
Heap walker: It's now possible to retain finalizer references in the heap dump options, also the weak reference inspections can retain finalizer references
MBean browser: Always add "ObjectName" attribute
MBean browser: Show keys in MBean tree
MBean browser: Search now also works on folders
Show non-modal messages for "Run GC" and "Save snapshot" actions

Bugs fixed:
Thread dumps view: Line numbers were not exported to HTML or copied to the clipboard
Improved detection of physical JDBC connections
Thread name changes were not tracked on Mac OS X with Java 7
Very large reference graphs or call graphs graphs would block the UI when nodes were opened
Method graph was re-layouted when nodes were removed
Mac OS X: Repeated use of the right arrow key did not open the call tree along the line of the maximum performance impact
Call tree view filters did not work as expected in several ways
When using inspections, some views could be empty when going back in the heap walker browser history
Calling Controller.triggerHeapDump() and Controller.triggerThreadDump() when the agent is not loaded printed an exception instead of an error message
Overhead of MBean browser could be high
"analyze" and "export" ant tasks did not have attributes for deobfuscation
"analyze" ant task did not have options for selecting retained reference types
File probe did not work correctly with streams created before recording started
Regression in 9.0: "Recorded objects" and "All objects" views did not contain primitive arrays when viewed in a snapshot
v9.0 [Jun 16, 2015]
JDBC probe: For Postgres, prepared statement execution was not recorded
Web service probe: Not all web service calls were tracked, for example when they were made from Weblogic
Probe telemetry comparison did not work if stacked telemetries were recorded (e.g. JPA/Hibernate)
Probe tracker did not work for formatted hot spots (e.g. JPA/Hibernate)
In snapshots, only the first activated probe displayed probe telemetry or probe tracking data
If instrumentation recording was started while a thread was inside a lambda, the call tree was corrupted
eclipse 4.5 integration did not work on Mac OS X

- Eclipse IDE integration failed if the previous eclipse installation directory was deleted.
- "Out of memory exception" trigger could not be edited.
- Fixed a crash while retransforming Java 8 Lambda classes.

- Heap walker: Optional retained size column in the classes view of the heap walker
- Heap walker: Action to use all retained objects for the current object set
- Heap walker: Actions to use retained objects for the selection in the classes and references views

Bugs fixed:
- Script classes were not recompiled when the selected JVM was changed
- Hot spots views: Exceptional methods runs were not merged in backtraces
- Session settings: Relative paths in java file paths were not interpreted as relative to the installation directory
v7.2 [Oct 8, 2012]
- New features:
- Biggest objects view in the heap walker: Objects in "cutoff" nodes can now be selected.
- Bundled integration for IntelliJ IDEA 12.x (the newest IDEA plugin is always available in time from the IDEA plugin manager).
- Bugs fixed:
- Platform API was partially broken (regression in 7.2).
- Monitor history and locking history graph: If a very large numbers of events were recorded, opening a snapshot could be very slow.
- Monitor history graph: For snapshots, the telemetry could not be zoomed out.
- Attaching to a 64-bit JVM from a 32-bit process did not work on Solaris and HP-UX.
- Attaching to a 64-bit JRockit JVM did not work.
- Sampling did not produce any results with Java 1.4 under some circumstances (regression in 7.0).
- Code samples in help were compressed to single lines.
- Mac OS X: IntelliJ Idea integration from JProfiler did not work.
- Fixed NPE in eclipse IDE integration.
v7.1 [Mar 13, 2012]
-A JPA/Hibernate probe has been introduced
v7.0 [Sep 1, 2011]
Probes. JProfiler now has a dedicated JEE & probes view section where you can record and analyze high-level data from various subsystems. There are built-in probes for:
JDBC
JMS
JNDI
Servlets
Files
Sockets
Processes
Probes can have the following views: In the time line view, the probe shows its control objects as colored bars along a time axis. Control objects are long-lived objects associated with single probe events. For example, in the JDBC probe, the control objects are the database connections. The colors on the time line bars correspond to the different states that the control object can be in.
