* Portability to MCL (Brian Mastenbrook)
* Workaround for Unicode-enabled SBCL (Brian Mastenbrook)

New in 0.9

* Portability to multiple lisps:
  - SBCL, as before
  - OpenMCL, threaded handlers only
  - Allegro, threaded handlers only
  - Armed Bear Common Lisp, threaded handlers only
  - CMUCL, serve-event only
  - CLISP, serve-event only
  - LispWorks, threaded (from Jochen Schmidt, based on Portable AServe)

In particular the CLISP support is a bit of a hack; timeouts are still
notably missing, and you must run (araneida:host-serve-events) after
you're done running start-listener on all of your listeners.

(Brian Mastenbrook, Jochen Schmidt)

* SERVE-EVENT fixes so that non-Araneida fd handlers can be
  added/removed during request handling.  More than slightly kludgey,
  and less than entirely thread-safe, but this can be blamed mostly on
  the nature of serve-event.  (Brian again, and Luis Oliveira)


New in 0.85

* Fix URL encoding for characters 0 to F (Fare Rideau)

* Add :www-authenticate keyword to request-send-headers, and
  :extra-http-headers for other stranger headers that it still doesn't
  know (Brian Mastenbrook)

* Clean up some of the HTML outputting stuff (impetus from Fare, but
  actual code not his fault; as far as I can see anyway)

New in 0.84

* Important bug fix: conditional request support had the sense of the
  "changed?" test backwards.  An upgrade is recommended for anyone 
  using this.

* Some notes on HTTP caching added to documentation

* New generic function LISTENING-P to detect whether an http-listener
  is active

New in 0.83

* Clear up RESPONSE-SENT so that it works as described.

* Convenient support for conditional GET requests: the new keyword
  argument :CONDITIONAL T to REQUEST-SEND-HEADERS will cause it to
  compare the last-modified date in the response with the
  if-modified-since date in the request, sending a 304 response
  and then signalling RESPONSE-SENT when appropriate.

* REDIRECT-HANDLER may now take a relative urlstring for :LOCATION,
  which is merged against the handler's base url

* Cleared up a lot (but not all) of the compilation warnings and
  style-warnings



New in 0.82

* SLIME integration: the SLIME debugger can now be used to debug
  errors that occur in handlers.  This is controlled by the 

* New variable *RESTART-ON-HANDLER-ERRORS*, which replaces the
  badly-named *BREAK-ON-HANDLER-ERRORS*.  It can contain a function
  which is run on handler errors to provide an alternative debugger
  interface

New in 0.81

* Fix for bug in doc/example.lisp: long-site-name doesn't (as I had
  claimed) necessarily have to return FQDN, and only did that on my
  machine because I had leftover bits of Debian common-lisp-controller
  it was looking at.  Thanks to Vincent Arkesteijn

* Export REQUEST-UNHANDLED-PART, which is the rightmost part of the 
  urlstring: what would have been in the second parameter of an 
  old-style handler

* STATIC-FILE-HANDLER coped badly with requests for ".../doc" when
  ".../doc/" is a directory.  Now issues redirect


New in 0.80

* New HTTP-LISTENER abstraction drastically improves the threaded
  variant of Araneida, and also replaces a lot of older ad-hocky code
  and global variables.  The following are at least obsolete, and may
  not even exist any more

  - The 'server' stuff: export-server etc
  - *root-handler*
  - install-{thread,serve-event}-handlers, remove-handlers

* Raising HTTP errors from handlers is now accomplished in a far
  cleaner fashion, by signalling CL conditions.  (This also means that
  parent handlers may handle these conditions to provide e.g. custom
  404 pages).  A condition exists for each 4xx and 5xx HTTP response code

* Add REFRESH header to REQUEST-SEND-HEADERS; sends the not-quite-HTTP
  'Refresh: ' header (really, not part of HTTP/1.0 or 1.1: it appears to
  have been a Netscape extension)

* Fix packaging problem in 0.72

New in 0.72

* Experimental HTTP/0.9 support.  Requests with no Host: header are served
  as though they were for *DEFAULT-SERVER*, and REQUEST-SEND-HEADERS is
  a no-op when (< (REQUEST-HTTP-VERSION R) 1)

* Fix bug in a FORMAT string spotted by new SBCL

New in 0.71 : bugfixes

* static-file-handler no longer calls peek-char, to avoid a bug in
  SBCL <0.8.3.

* new variable *break-on-handler-errors* controls whether errors encountered 
  during a request read or response (almost any code in Araneida,
  including request parsing, dispatch, etc) cause a break into the
  debugger or not

* Incompatible change: html-stream has new and experimental behaviour
  if you put a function in the tree: it invokes the function, passing the
  output stream as its only parameter.  This is experimental and I
  hope it won't affect anyone much - does anyone currently print function
  objects in their html streams?

* Added LINK to the list of empty elements

* New prettier implementation of body-params which goes about twice as
  fast (thanks to Zach Beane)

* Minor docn updates

New in 0.70

* Experimental MP support, only on SBCL with #+sb-threads configured

* Dead code cleanup: removed package aliases HTTPSRV and HTTP-SERVER
  and references to them

* HTTP header parsing code is slightly less consy

* MERGE-URL fix

* Now uses SB-BSD-SOCKETS; DB-SOCKETS no longer required


New in 0.69 

* All-new handler model, with prototype documentation - unpolished,
  but should be enough to get started.  

* Default handlers REDIRECT-HANDLER and FILE-REQUEST-HANDLER  - see
  relevant source files for details

* Examples are no longer included, as they're all terrifically out of
  date

* (Actually, they were missed out of the last version too, but it
  was accidental that time)

* This is essentially a beta for 0.7, which will have bug fixes (if
  anyone sends bug reports) and better examples.


New in 0.63

* SEND-FILE (and thus FILE-REQUEST-HANDLER) test explicitly and return 404
  for wild pathnames.

New in 0.62

* URL merging bug fixes

New in 0.61 (relative to 0.6)

* now depends on SPLIT-SEQUENCE package (available the same place you
  found this)

* Socket error handling change: STREAM-ERROR is assumed to be due to the
   peer going away, and not worth calling the error handler for

* Bug fixed: now correctly handles folded lines in the HTTP header

* New function REQUEST-COOKIE

* FTP protocol "support" in url functions

* Fix broken base64 decoder

New in 0.54 - Thu, 28 Jun 2001 

* Araneida is now a cCLan package

* Araneida 0.52 (unreleased) and later also work with SBCL - in fact,
  most of the testing these days is done with SBCL.  Has been used on
  Linux i386 and Alpha; would be interested to receive success/failure
  reports (and especially patches) from users on other platforms.

New in 0.51 - Sun Jan  7 02:31:10 GMT 2001

* better support for conditional GET and If-Modified-Since headers

* some speed improvements to the sexp-to-HTML convertor

* new pattern-based sexp rewriting engine, so that you can for example
write

(define-page
 ((merge-url *araneida-url* "/rewritten")
  :patterns example-patterns
  :changed-time (get-universal-time))
 '(page
   (title "foo")
   (body (h1 "title") (p "hello " (red "red") " world")))))

and have it transformed into HTML in a fairly arbitrary (and more
general than CSS) fashion.  See example 6 in <a
href="../examples/main.lisp">main.lisp</a> for details (including the
definiton of the rewriting patterns) and <a
href="/rewritten">/rewritten</a> for the output
