<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In RandomTimer class, protected instance timer has been replaced by getTimer() protected method, this is related to <bugzilla>58100</bugzilla>. This may impact 3rd 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 (__javaScript, IfController). If you want to use it, use property <code>javascript.use_rhino=false</code>, see <bugzilla>58406</bugzilla>.
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.
<li>Since version 3.0, JMS Publisher will reload contents of file if Message source is "From File" and the ""Filename" field changes (through variables usage for example)</li>
<li>org.apache.jmeter.gui.util.ButtonPanel has been removed, if you use it in your 3rd party plugin or custom development ensure you update your code. See <bugzilla>58687</bugzilla></li>
<li>MongoDB elements (MongoDB Source Config, MongoDB Script) have been deprecated and will be removed in 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 HH:mm:ss (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>org.apache.jmeter.protocol.http.visualizers.RequestViewHTTP.getQueryMap signature has changed, if you use it ensure you update your code. See <bugzilla>58845</bugzilla></li>
<li>JMS Subscriber will consider sample in error if number of received messages is not equals to expected number of messages. It previously considerer sample OK if only 1 message was received. See <bugzilla>58980</bugzilla></li>
<li>Since version 3.0, HTTP(S) Test Script recorder uses default port 8888 as configured when using Recording Template. See <bugzilla>59006</bugzilla></li>
<li>Since version 3.0, the parser for embedded ressources (replaced since 2.10 by Lagarto based implementation) relying on htmlparser library (HtmlParserHTMLParser) has been dropped as long as its dependencies.</li>
<li>Since version 3.0, default property's value <code>http.java.sampler.retries</code> has been switched to 0 (no retry by default) to align it on HttpClient4's behaviour.
Note also that its meaning has changed, before 3.0, <code>http.java.sampler.retries=1</code> meant No Retry, since 3.0 it is more litteral, <code>http.java.sampler.retries=1</code> means 1 retry.

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.
