Sure, there are the usual suspects:

-          Query of Queries, User Defined Functions, CFGRAPH, CFFLUSH, Verity K2, and more

-          System Monitoring/Reporting/Logging/Archival features; Performance/memory enhancements

But are you aware of the following other new features, to name just a few:

-          you can now query a datasource without needing a datasource (dsn) defined in the admin

-          how dsn-less connections have “maintain connections” on by default, & how to change that

-          CFSAVECONTENT, CFOBJECTCACHE, the incredibly useful CFDUMP

-          how CFSAVECONTENT can be used to cache slow, “nearly static” portions of a page

-          the new dynamic java class loader for working with java objects

-          you can validate input with regular expressions within CFFORM

-          the new updated TagInfusion pack for Studio 4.5.2, holding the tag definitions/help for R5

-          you can now add your own templates/applications to the administrator interface

-          how to use the new Merant Wire protocol drivers, and where to find add’l docs within CF

-          GetHTTPRequestData() for SOAP processing, GetException() for Java processing

-          CFGRID is enhanced, including drop-down lists, checkboxes, columns that sort on dbl-click

-          enhanced resource view for advanced security, and the new buttons to flush its cache

-          a change in licensing allowing use of a single license on multiple OS’s (on a single machine)

-          there are pre-built examples of CFGRAPH, UDF, Query of queries, CFGRID

And even among the “usual suspects”, did you know about the following features, to name several:

-          the 9 tags that create result sets useful for query of queries, CFGraph, and more

-          when a query of queries makes sense, and when it doesn’t

-          when user defined functions (UDFs) make sense, and when they don’t

-          public UDF libraries, like CFLib.org with dozens of open source string/math/data/security UDFs

-          you can setup CFGraphs to support drill-down by clicking on a bar or pie wedge

-          you can also graph non-query data, passing one more values with CFGRAPHDATA

-          the 6 tags that you can’t use on a page that does CFFLUSH, such as CFLOCATION/CFCOOKIE

-          Verity K2 Server supports site spidering, searching remote servers, and more

-          every change to the administrator is now tracked and can be reported/monitored

-          how to setup both “default” and “custom”  server probes in the Monitor feature

-          the purpose of the tools in cfusion\cfam\btauxdir

-          you can setup probe to monitor a remote server (such as a hosted server) to track any failures

-          how to setup an email notification process for one, rather than simply all, probes

-          you can use the archive/deploy feature to serve up packaged applications to remote visitors

-          archive builds can be scheduled to occur on a scheduled, recurrent basis

And were you aware of some of the challenges you may need to solve, including:

-          what hotfixes you must apply to resolve common problems using certain new features

-          what easy mistake in using CFGRAPH will crash the graph server

-          what the install of CF5 will/may do to your existing JRun setup

-          what critical Siteminder installation issues exist and steps you’ll need to take

-          how to troubleshoot/tune the graph, report, monitor servers

-          WHERE clause matching in query of queries is unexpectedly case-sensitive

-          query of queries date processing doesn’t support ODBC dateformat

-          performance reports are based on samples within interval, not a sum of all occurences in interval

And did you know about some things broken previously that are now working, to name just a few:

-          the duplicate() function now works as expected

-          an improperly formatted file in mail spool no longer causes all spool files to never be sent

-          the “Disable database connection” feature for DSNs in the Admin now works as expected

And there are still more topics he’ll discuss in each area!
