<ch_title>New Search Feature in View Results Tree to allow searching for text / regexp in Request/Responses/Headers/Cookies/… This will ease correlation and Test plans creation</ch_title>
<p>JSON is now a first class citizen in JMeter with the introduction of a new <ahref="http://goessner.net/articles/JsonPath/"target="_blank">JSONPath</a> post processor.
This post processor is very similar to Regular Expression Post Processor but is well suited for JSON code.
It is based on <ahref="https://github.com/jayway/JsonPath"target="_blank">Jayway JSON Path library</a>
<ch_title>New validation feature, in one click run a selection of Thread Groups with <code>1</code> user, no pause and <code>1</code> iteration</ch_title>
<p>A new "<code>Advanced</code>" tab has been added to HTTP Request to simplify configuration. The file upload feature has been moved into a dedicated tab.
<p>Migration to HttpClient 4.5.2 improves the following fields of JMeter:
<ul>
<li>Support of recent RFC like <ahref="https://tools.ietf.org/html/rfc6265"target="_blank">HTTP State Management Mechanism RFC-6265 for Cookies</a>, you should use now <code>HC4CookieHandler</code> in HTTP Cookie Manager component</li>
<li><ahref="https://en.wikipedia.org/wiki/Server_Name_Indication"target="_blank">Server Name Indication (SNI)</a> support for HttpClient4 implementation</li>
<li>Improved and better performing validation mechanism for Stale connections and Keep-Alive management, see properties <code>httpclient4.validate_after_inactivity</code> and <code>httpclient4.time_to_live</code></li>
<li>Many bug fixes since previous version 4.2.6 used in JMeter 2.13, see <ahref="http://www.apache.org/dist/httpcomponents/httpclient/RELEASE_NOTES-4.5.x.txt"target="_blank">HttpClient 4.5.X release notes</a></li>
<li>Better support of HTTP RFC 2616 / RFC 7230 and fixes to issues with <code>deflate</code> compression management</li>
<li>Parsing of CSS imported files (through <code>@import</code>) or embedded resources (background, images, …)</li>
<li>Lazy initialization of SSL context: For 15 Threads 138% more sampling in 5 minutes for HTTP only tests. Gain increases as number of threads increases</li>
<li>Rework of Connection management for Parallel Download: This now reproduces nowadays browsers behaviour and improved throughput. For 15 Threads 135% extra samples in 5 minutes.</li>
<li>Total of 750% more throughput found on test with 15 threads, the more threads you have the more the gain</li>
<li>You can now compute and store just the MD5 of embedded resources instead of storing the entire response, this can be done by setting <code>httpsampler.embedded_resources_use_md5=true</code> property</li>
<p>Around 40 UI fixes have been made to either fix buggy, confusing behaviour or simplify usage by not allowing incompatible options to be selected</p>
Creating and testing a Test Plan before Load Test has been much simplified by allowing you to only start a selection of Thread Group, start them without applying Timers (thus gaining time)
or start them using a new Validation mode. This validation mode allows you to start a Thread Group (without modifying it) with 1 thread, 1 iteration and without applying timers.
<li>Since version 3.0, Groovy-2.4.6 is bundled with JMeter (<code>lib</code> folder), ensure you remove old version or referenced versions through properties <code>search_paths</code> or <code>user.classpath</code></li>
<li>Since version 3.0, <code>jmeter.save.saveservice.assertion_results_failure_message</code> property value is true, meaning CSV file for results will contain an additional column containing assertion result response message, see <bugzilla>58978</bugzilla></li>
<li>Since version 3.0, <code>jmeter.save.saveservice.print_field_names</code> property value is true, meaning CSV file for results will contain field names as first line in CSV, see <bugzilla>58991</bugzilla></li>
<li>Since version 3.0, <code>jmeter.save.saveservice.idle_time</code> property value is true, meaning CSV/XML result files will contain an additional column containing idle time between samplers, see <bugzilla>57182</bugzilla></li>
<li>In RandomTimer class, protected instance <code>timer</code> field has been replaced by <code>getTimer()</code> protected method, this is related to <bugzilla>58100</bugzilla>. This may impact 3<sup>rd</sup> party plugins.</li>
<li>Since version 3.0, you can use Nashorn Engine (default javascript engine is Rhino) under Java8 for Elements that use Javascript Engine (<code>__javaScript</code>, <code>IfController</code>). If you want to use it, use property <code>javascript.use_rhino=false</code>, see <bugzilla>58406</bugzilla>.
<note>Note in future versions, we will switch to Nashorn by default, so users are encouraged to report any issue related to broken code when using Nashorn instead of Rhino.</note>
<li>Since version 3.0, JMS Publisher will reload contents of file if Message source is "<code>From File</code>" and the "<code>Filename</code>" field changes (e.g. if it uses a variable)</li>
<li>org.apache.jmeter.gui.util.ButtonPanel has been removed, if you use it in your 3<sup>rd</sup> party plugin or custom development ensure you update your code. See <bugzilla>58687</bugzilla></li>
<li>Property <code>jmeter.errorscounter.display</code> has been removed, errors/warnings counter is now always displayed. See <bugzilla>59236</bugzilla></li>
<li>Property <code>xml.parser</code> has been removed, it is not used anymore as <code>org.apache.jmeter.util.JMeterUtils#getXMLParser</code> has been deprecated and is not used neither. See <bugzilla>59236</bugzilla></li>
<li>MongoDB elements (MongoDB Source Config, MongoDB Script) have been deprecated and will be removed in the next version of jmeter. They do not appear anymore in the menu, if you need them modify <code>not_in_menu</code> property. JMeter team advises not to use them anymore. See <bugzilla>58772</bugzilla></li>
<li>Summariser listener now outputs a formated duration in <code>HH:mm:ss</code> (Hour:Minute:Second), it previously outputed seconds. See <bugzilla>58776</bugzilla></li>
<li>WebService(SOAP) Request and HTML Parameter Mask which were deprecated in 2.13 version, have now been removed following our <ahref="./usermanual/best-practices.html#deprecation">deprecation strategy</a>.
Classes and properties which were only used by those elements have been dropped:
<li><code>org.apache.jmeter.protocol.http.visualizers.RequestViewHTTP.getQueryMap</code> signature has changed, if you use it ensure you update your code. See <bugzilla>58845</bugzilla></li>
<li><code>__jexl</code> function (i.e. JEXL 1) has been deprecated and will be removed in next version. See <bugzilla>58903</bugzilla></li>
<li>JMS Subscriber will consider a sample to be in error if number of received messages is not equals to expected number of messages. It previously considered a sample OK if at least 1 message was received. See <bugzilla>58980</bugzilla></li>
<li>Since version 3.0, HTTP(S) Test Script recorder uses default port <code>8888</code> as configured when using Recording Template. See <bugzilla>59006</bugzilla></li>
<li>Since version 3.0, the parser for embedded resources (replaced since 2.10 by Lagarto based implementation) relying on htmlparser library (HtmlParserHTMLParser) has been dropped along with its dependencies.</li>
<li>Since version 3.0, the default property value for <code>http.java.sampler.retries</code> has been switched to <code>0</code> (no retry by default) to align it with the behaviour of HttpClient4.
<note>Note also that its meaning has changed: before 3.0, <code>http.java.sampler.retries=1</code> meant <code>No Retry</code>, since 3.0 <code>http.java.sampler.retries=1</code> means <code>1</code> retry.
(Note: this only applies to the Java HTTP Sampler)</note>
<li><code>httpsampler.await_termination_timeout</code> has been replaced by <code>httpsampler.parallel_download_thread_keepalive_inseconds</code> which is now the keep alive time for the parallel download threads (in seconds).</li>
<li>For Thread Group Test Element, the property "<code>Action to be taken after a Sample Error</code>" value has been switched from "<code>Continue</code>" to "<code>Start Next thread loop</code>". See <bugzilla>59152</bugzilla></li>
