* Prerequisites
** Prerequisites included in the distribution
- arnesi
- yaclml
- cl-icu
- iterate
- mod_lisp
** Prerequisites you must download and install manually
- a recent CVS version of SLIME. You must have the new inspector for
the ucw-inspector to work.
- portableaserve 1.2.35 should you want the aserve backend.
* Changes (since 0.3.3)
* Components
- A new class, simple-window-component, provides the convience
render-on method and slots. The window-component class is now used
for call/answer logic only. Previously these two jobs were both
handled by the window-component class, this made template based
window-components impossible.
- window-component now properly deals with the case where it _does_
have a calling component. This makes call'ing window-components
from regular actions meaningfull.
- range-view component has new cleaner api. variosu bugs and
off-by-one errors have been fixed.
* Component Rendering
- User errors during the rendering phase are now properly dealt with
(iow they don't cause an internal server error).
- *print-level*, *print-length* and now set to low values when
printing the backtrace (this avoids 500Kb backtrace pages). The
entire data structure is still availabe by inspecting the objects.
- template-component-environment now uses nconc method combination.
* Component Control Flow
- CALL and ANSWER can now be used in defentry-point with the
"expected" semantics. The only restriction is that the called
components must be subclasse of window-component.
* RERL
- session frames are now stored in a hash table and are never
removed. this change is required to support window cloning (whethere
this change should be appiled globally or a sub class of
standard-session-frame should be created is still up for debate).
- Errors during find-application now show an error page instead of
killing the server.
* Other
- Created a new ucwctl script which, once properly edited for the
site, can be used in /etc/init.d to control a ucw server.
- UCW now loads the init.lisp file. This provides a convient place to
put site specific startup code.
- Obselete method definitions in the example app have been removed.
- A tla config has been added to the libs directory which makes
getting arnesi et al. easier.
- A good deal of work has gone into the manual.
* Known Issues
- The transaction example does not work.
- CMUCL and SBCL have a bug in the handling of :default-initargs,
which UCW makes heavy use of.
* Supported Platforms
OpenMCL and CMUCL (with mod_lisp) backend have been tested
throughly. SBCL and mod_lisp have been tested lightly. aserver
backend has not been tested.

Forget your perfect offering.
There is a crack in everything.
That's how the light gets in.
