January 31st, 2013Core Improvements:
· A new Extractor that uses CSS or jquery-like selector syntax has been introduced, it allows using either JODD or JSOUP implementations
· JMeter can now handle different types of documents (PDF, MsOffice files, Apache OpenOffice's files...) within different elements
· A new Regex User Parameters Pre-Processor that enables injecting input parameter names and values using a reference extracted by Regular Expression Extractor from a previous response
· TCP Sampler has been enhanced with new options to allow setting Close Connection , SO_LINGER and End of line(EOL) byte value
· n __escapeOroRegexpChars(,) has been introduced quote ORO regexp meta characters
· ForEach Controller has now 2 new fields to control start and end of loop
· Result Status Action Handler now has a new option to "Start next thread loop"
· JMS Publisher can now send Bytes Messages
· Memory and performance improvements: significant improvements have been done in this version on memory usage per Thread and CPU when more than one Post Processor is used as child of a Sampler

GUI and ergonomy Improvements:
· Search feature has been improved to search within more internal fields of elements and expand search results
· Copy/paste is now possible between 2 JMeter instances >= 2.9 version

HTTP Proxy Server recording:
· HTTP Proxy Server now automatically uses HTTP Request with Raw Post Body mode for samples that only have one unnamed argument (JSON, XML, GWT...)
· HTTP Proxy Server does not force user to select the type of Sampler in HTTP Sampler Settings, this allows easier switch between implementations as Sampler do not have this information set anymore
· SamplerCreator interface has been enriched to meet new requirements for plug-in providers
· It is now possible to create binary sampler for x-www-form-urlencoded POST request by modifying proxy.binary.types property to add application/x-www-form-urlencoded

September 29th, 2009· Bug 47321 - HTTPSampler2 response timeout not honored
· Bug 47290 - Infinite loop on connection factory lookup (JMS)
· JDBC Sampler should not close Prepared or Callable statements as these are cached

· Bug 47377 - Make ClassFinder more robust and close zipfile resources
· Fix some errors in generating the documentation (latent bug revealed in 2.3.3 when Velocity was upgraded).
April 23rd, 2009Incompatible changes:
· To reduce the number of classes loaded in non-GUI mode, Functions will only be found if their classname contains the string '.functions.' and does not contain the string '.gui.'. All existing JMeter functions conform to this restriction. To revert to earlier behaviour, comment or change the properties classfinder.functions.* in jmeter.properties.
· The reference value parameter for intSum() is now optional. As a consequence, if a variable name is used, it must not be a valid integer.
· The supplied TCPClient implementation no longer treats tcp.eolByte=0 as special. To skip EOL checking, set tcp.eolByte=1000 (or some other value which is not a valid byte)
· Leading and trailing spaces are trimmed from variable names in function calls. For example, ${__Random(1,63, LOTTERY )} will use the variable 'LOTTERY' rather than ' LOTTERY '.
· Synchronization has been removed from the RunningSample class (it was not fully threadsafe anyway). Developers of 3rd party add-ons that use the class may need to synchronize access.
