Noteworthy Enhancements
* give visibility to templates and partials in Rails 2.1 and later, in
dev mode and production
* change active record metrics to capture statistics in adapter log()
call, resulting in lower overhead and improved visibility into
different DB operations; only AR operations that are not hitting the
query cache will be measured to avoid overhead
* added mongrel_rpm to the gem, a standalone daemon listening for custom
metric values sent from local processes (experimental); do mongrel_rpm
--help
* add API for system monitoring daemons (refer to KB articles); changed
API for manual starting of the agent; refer to
NewRelic::Agent.manual_start for details
* do certificate verification on ssl connections to
collector.newrelic.com
* support instances appearing in more than one application by allowing a
semicolon separated list of names for the newrelic.yml app_name
setting.
* combined agent logfiles into a single logfile
* use rpm server time for transaction traces rather than agent time
Developer Mode (only) Enhancements
* show partial rendering in traces
* improved formatting of metric names in traces
* added number of queries to transactions in the transaction list
* added some sorting options for the transaction list
* added a page showing the list of active threads
Compatibility Enhancements
* ruby 1.9.1 compatibility
* support concurrency when determining busy times, for 2.2 compatibility
* in jruby, use Java used heap for memory sampling if the system memory
is not accessible from an unsupported platform

rake tasks
