<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.
<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>
<ch_title>JSR223 Test Elements do not require a Cache Compilation Key anymore</ch_title>
<p>Just check <code>Cache compiled script if available</code> checkbox and the elements (Pre-Processor, Post-Processor, Assertions, Listeners...) will pre-compile the script if underlying language supports it and cache the compiled code</p>
To enable <atarget="_blank"href="http://www.oracle.com/technetwork/articles/java/jf14-nashorn-2126515.html">Nashorn</a>, you need to set in <code>user.properties</code>:
<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.
<li><ahref="https://en.wikipedia.org/wiki/Apdex"target="_blank">APDEX</a> table that computes for every transaction the APDEX based on configurable values for tolerated and satisfied thresholds</li>
<li>A Statistics table providing in one table a summary of all metrics per transaction including 3 configurable percentiles : <figurewidth="1376"height="433"image="changes/3.0/report_statistics.png"></figure></li>
<li>An error table providing a summary of all errors and their proportion in the total requests : <figurewidth="1344"height="455"image="changes/3.0/report_errors.png"></figure></li>
<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 and select <code>standard</code> Cookie policy</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>JDBC Request and JDBC Connection Configuration have been updated to replace old Excalibur Pool by Apache Commons DBCP2 pool. As a consequence properties have been migrated to equivalent
<p>JMeter has a new Logo created by Felix Schumacher. <br/>Icons have also been refreshed to give a more modern style and make them more meaningful</p>
<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.
<ch_title>Configuration simplification with better defaults</ch_title>
<p>Default values for many properties have been modified to make JMeter configuration optimal Out of the box. Read "Incompatible changes" section for more details.</p>
<ch_title>Apache Groovy bundled with JMeter</ch_title>
<p><ahref="http://www.groovy-lang.org/"target="_blank">Apache Groovy</a>, the well-known JVM scripting language, is now bundled with Apache JMeter in lib folder.
This allows you to use it immediately through JSR223 Elements by selecting the Groovy language.</p>
<ch_title>Superflous and old properties removed</ch_title>
<p>Old properties that existed to maintain backward compatibility or to offer some superflous customization have been removed.
Read "Incompatible changes" section to see which properties have been removed.</p>
<ch_title>Code and documentation improvements</ch_title>
<ul>
<li>Migration to Java7 source code and use of its syntactic sugar</li>
<li>Major code cleanups</li>
<li>Full review of documentation and improvement both in content and presentation</li>
<ch_title>Slf4j can now be used within Plugins and core code</ch_title>

<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>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><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>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>JDBC Request has been updated to use commons-dbcp2, since then the behaviour is slightly different, ensure you have a correct "Validation Query" for your database. See <bugzilla>58786</bugzilla></li>
<li>Number of redirects followed by JMeter is now 20, it was previously 5. This can be changed with property <code>httpsampler.max_redirects</code>. See <bugzilla>59382</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>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>__jexl</code> function (i.e. JEXL 1) has been deprecated and will be removed in next version. See <bugzilla>58903</bugzilla></li>
<li>Spline Visualizer listener and Distribution Graph listener 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>58791</bugzilla></li>

<li>Philip Helger (http://www.helger.com) for his <ahref="https://github.com/phax"target="_blank">CSS Parser</a> and for taking into account our bug reports very rapidly</li>
The fix is to run JMeter as Administrator, it will create the registry key for you, then you can restart JMeter as a normal user and you won't have the warning anymore.
</li>

With Oracle Java 7 and Mac Book Pro Retina Display, the JMeter GUI may look blurry.
