@carehart
Some intro questions for you
• How many have started using CF2016 in prod? In dev?
• Have at least seen resources about it?
• Not surprised if few: people often wait
• Anyone “waiting for first point release”?
• Have been 3 updates already
• How many likely won't use it until next release comes out (CF2018, or whatever)?
• I do these talks, not just for those making the move now, soon, or have already
• But also those who may see it in future 
• Anyone know when I started doing hidden gems in CF?
• 4.0.1 in 1999
• So, let’s look first at the major new features (only brief overview)

Major features of CF2016
• API Manager
• Security Code Analyzer
• PDF Improvements (redaction, sanitization, more)
• CFML language improvements (tags, functions, and more)
• Security improvements (especially more NTLM support)
• Performance improvements
• More about some of these later
• Now, on to the more “hidden” gems!

@carehart
Installation gems
• Removal of Akamai Download Manager!
• Previously, when downloading CF installer from Adobe, we were forced to use this
• Now just generally a better experience (I suppose some may miss it)
• carehart.org/blog/client/index.cfm/2016/2/19/cf2016_download_no_longer_requires_Akamai_DL_mgr
• Unfortunately, CF install has gotten huge because of API Manager
• Especially tragic if you’ll be using CF Standard: by license can’t use API Mgr
• This is “to be fixed” (bugbase.adobe.com/index.cfm?event=bug&id=4155910)
• During installation, you’re asked whether/how to install API Manager
• And whether to implement it within JVM or as own service

Configuration gems
• CFscripts folder now moved to its own directory, not in CFIDE!
• Great move for security, administration
• New folder called cf_scripts, found in the cfusion wwwroot
• Pointed to as a virtual directory in IIS, Apache, etc.
• Related to this…
• CF Admin now available only via internal web server by default
• This is another very good thing, for security
• You REALLY should not try to override this, but I discuss options in my blog post below
• Let’s move on to gems WITHIN the CF Admin…

Administration gems
• CF Admin option to store CF sessions in redis (cache) rather than heap
memory
• helpx.adobe.com/content/help/en/coldfusion/2016/external-session-storage.html
• Gotcha: works only with CF sessions, not “J2EE sessions”
• Those using “j2ee sessions” could modify Tomcat (underlying CF) on their own
• blog.svajlenka.com/post/125784752315/redis-and-coldfusion-because-why-not
• New admin setting to disable “REST discovery” by API Manager
• See Settings page, last setting
• For more on these admin and config changes, see
• carehart.org/blog/client/index.cfm/2016/2/23/cf2016_CF_Admin_changes

Web server config tool (wsconfig) gems
• Many new improvements related to the web server config tool
• Fixed: no longer any need to manually reconfigure connectors after update!
• CF Update mechanism handles this for us automatically now
• WSConfig offers new “upgrade” option, if ever needed
• Fixed: for those using multiple instances (in CF Enterprise/Trial/Dev)
• Wsconfig UI finally offers option to pick instance name to connect to (like <= CF9)!
• In CF10/11, we had to start wsconfig in instance’s runtimebin to connect site to it
• Fixed: if you open wsconfig UI while already open, you no longer get blanks
• You get warning that you may already have it open
• …

Web server config tool (wsconfig) gems (cont.)
• WSConfig UI now tracks number of sites in web server configured or not
• Now offers both an "all" option (for all sites) and an "all - individually“
• Which instead creates a new connector for each site (using the selected settings)
• Appears only if you do have more than 1 web site in web server
• Wsconfig UI now offers option to all 3 connector tuning args
• Found under “advanced settings”
• Previously only offered connection_pool_timeout, max_reuse_connection
• Now offers allows configuration of connection_pool_size also
• Sadly, installer’s web config step does not offer these 3 configurable options
• Due to be fixed in a new installer: bugbase.adobe.com/index.cfm?event=bug&id=4155913
• …

Web server config tool (wsconfig) gems (cont.)
• Connector now defaults to timeout of 60 (seconds); was 0 (infinite) before
• For IIS: better connector tuning settings for 2-site setup by default
• Conneciton_pool_size (500), max_reuse_connections (250):
• Sadly, for now, this is not so for Apache configs, but is due to be fixed in upcoming update
• CF2016 also now includes maxthreads="500" and connectionTimeout="60000" in
server.xml, by default
• “Advanced Settings" now also offers "skip iis custom errors" option
• Disabled by default. Useful for some scenarios
• Needed to add manually to isapi_redirect.properties file in CF10/11
• Nice to see all these improvements to the wsconfig, which has been a source of
heartburn in CF10 and 11. Let’s move on to other gems…

New feature gems
• New command-line interface (CLI)
• Allows cmd line CFML execution by pointing to a cfm file, via cf.bat
• As in, cf.bat some_file.cfm
• Not a real interactive shell (with tab completion, etc.)
• No repl, no package manager, no extensibility as with CommandBox project
• Still, is useful for cron jobs/windows scheduler, etc. to run cfml pages
• Quite a few options and capabilities
• For more, see
• helpx.adobe.com/coldfusion/2016/command-line-interface.html

Changed feature gems
• Many enhancements to PDF support
• Mentioned before sanitization, redaction, but also:
• Export/import of comments, metadata
• Archiving, including newer PDF/A-2b and -3b standards
• Support for attachments, stamps
• For more, see substantial article with examples, and code download
• adobe.com/devnet/coldfusion/articles/pdf-enhancements.html
• Not mentioned on that page:
• CFPDF adds new encrypt attribute values: AES_256R5 and AES_256R6
• …

Changed feature gems (cont.)
• New argument for structnew, ordered, maintains insertion order
• Looping over such a struct will also return in insertion order
• All other forms of creating new structs keep same order as before
• Also support for creating empty ordered struct
• helpx.adobe.com/coldfusion/2016/language-
enhancements.html#CollectionsupportOrdered
• …

• New application-level controls
• searchImplicitScopes, passArrayByReference
• Each can change long-standing behavior for these operations, vastly improving
performance (5x and 25x, respectively)
• Set as either cfapplication attributes or via this scope in application.cfc
• See:
• adobe.com/devnet/coldfusion/articles/language-enhancements-cf-2016.html
• helpx.adobe.com/coldfusion/2016/language-enhancements.html#Scopesearch
• helpx.adobe.com/coldfusion/2016/language-enhancements.html#Arraysbr
• …

• CF Admin “enable whitespace management” option now suppresses
whitespace at compile time as well as runtime
• Swagger doc generation (for restful api's and API Manager)
• helpx.adobe.com/coldfusion/2016/swagger-document-generation.html
• Now on to language enhancements…

@carehart
New language constructs
• Safe navigation operator (?.)
• Used when accessing members of a struct or values of an object
• Used instead of ".", to prevent exception if not defined, null, etc.
• Simplified code, versus nested isdefined tests
• Examples:
• <cfoutput>#employee?.firstname#</cfoutput>
• Will output empty string if firstname does not exist/null
• Writeoutput(employee?.name?.firstname?.trim());
• Will output empty string if all 3 are undefined/null
• …

What’s new in Standard vs Enterprise
• Referring here only to what’s new/changed in CF2016 and in Enterprise only
• API Manager
• Security Analyzer
• These do not work with CF 2016 Standard, nor even Developer edition!
• They do work with the CF Trial edition
• And you can take an enterprise license key and use it on a “dev” machine, of course
• More:

Single page listing all CF2016 updates
• Lists updates, links to technotes, and offers jar download links!
• helpx.adobe.com/coldfusion/kb/coldfusion-2016-updates.html
• Also available for CF 11 and 10:

Traps/gotchas
• Can no longer access CF11 installers on Adobe site
• Look to cfmlrepo.com (community-run site)
• Can’t even license CF11 anymore
• Must buy CF2016 and request “backward license” to CF11
• Annoying: while there are PDFs of CF docs…
(helpx.adobe.com/coldfusion/home.htm)
• They generally show only one level within a section, then offer a link to online page for
more detail (sometimes confusing)
• …

Traps/gotchas (cont.)
• Mentioned previously
• Security Analyzer works only with CF Enterprise (or trial)
• Also requires CF installed in “Developer mode”, with RDS enabled
• API Manager included in CF download, whether you can or want to install it
• New redis-based session vars support only CFML sessions, not j2ee sessions
• CF Installer web server config does not yet offer tuning options
• See other (few) “known issues” listed in original release and update docs
• Be sure to apply updates before believing web reports of “known bugs”. May
since have been fixed!
