Clarion 9 build 10241 is the first release of C9 to CSP program participants.
There was no change list included with the release email.
Speed improvements
Some devs are reporting significant speed improvements within the IDE,
Registry issues using C8 within C9
If you use C9 to host your C8 development (rather than installing each version separately, which is the default) then C9 will make your C8 registry unreadable from the C8 IDE, as the registry format has changed.
Problem generating/building DLLs
The IDE throws a generation error when creating code for DLLs. The app will build but as no EXP file is generated you can't use the DLL (at least not by linking in the DLL's lib). Diego says this will be fixed in the next build.
Start page styling
There's been some grumbling about a change to the IDE that internalized start page styling so it can no longer be customized via layout.css.
Can you ship product with this release?
At least one dev is shipping C9-built apps to customers with no reported issues.
SQLite driver
Not sure I completely understood the discussion, but it appears blob contents are not being copied as expected.
Report generator interface changes
There have been some changes to the report generator interface so if you have older source or an older version of a third party product that uses this interface you'll need to get the update or modify the source.
Possible duplicate symbols
Diego: "Most of the symbols from Win32ext.lib were merged with the Win32.lib in C9."
%Parameters is read only
In C9 there is only one prompt for prototypes (as there should be). Older templates that attempt to set the %Parameters value will trigger an error. In the old days Clarion code had labels in parameters and data types in prototypes. For years now it's been best practice to have parameters and prototypes declared exactly the same (except that for procedure/method implementations you have to leave off the return type if any, which seems pretty silly to me).
/ConfigDir
Graham Dawson has reported problems with Clarion not registering drivers when the /ConfigDir IDE switch is used.
