- On Linux, abstract sockets are now supported for agent to daemon communication. An abstract socket can be created by prefixing the value of the port setting in your newrelic.ini file (e.g.
newrelic.daemon.port = "@newrelic-daemon") or newrelic.cfg file (e.g.
port = "@newrelic-daemon").
- The daemon can now be passed a
--define <setting>=<value>flag that allows setting arbitrary parameters from your newrelic.cfg file. These parameters will take precedence over settings from that file.
- Drupal 8 requests that are successful full page cache hits for anonymous users (handled by Drupal\page_cache\StackMiddleware\PageCache) are now given the name WebTransaction/Action/page_cache.
- Support for automatically naming transactions has been added for Symfony 2.8 and 3.0.
- Support for automatically naming transactions has been added for MediaWiki 1.18.0 and newer.
- It is now possible to disable reporting of errors for exceptions that are handled by an exception handler installed with
set_exception_handler()by enabling the
- Calls to newrelic_notice_error with improper parameters will no longer record an error with the message "?". Instead, no error will be recorded. newrelic_notice_error will now return true if an error is saved, null if the arguments are invalid, and false otherwise. If newrelic_notice_error is called with two parameters and the second parameter is not a valid exception, no error will be recorded: The first parameter is now entirely unused.
- On Redhat Enterprise Linux 7 and related systems such as CentOS and Fedora, the
systemctl start|stop newrelic-daemoncommands were not working due to a bug in the newrelic-daemon init script when executed by systemd. This has been fixed.
- On some Linux systems, an SELinux policy could prevent the newrelic-daemon from determining the correct hostname. Affected systems were unable to report data because a valid hostname is required by New Relic. This has been fixed. This issue could also prevent the newrelic-daemon from determining the correct hostname when running in a chrooted environment, or any environment in which access to the /proc filesystem is limited.
- Detection of Zend Framework 2.5 and later was unreliable when the framework was installed via Composer. This has been fixed.
- Detection of Laravel 5.1 and later was unreliable when
artisan optimizewas used. This has been fixed.
- The agent now sends the attribute
request.headers.contentLengthas an integer rather than a string.
