The final, unless someone says something, release announcement that I
have is below.
Sam: if you want to change it, please do so soon.
----------------------------------------------------------------------
* This is the last release that includes ProfessorJ. As of the
next release, Kathy Gray who created and maintained the
Professor will move the code to planet and maintain only at a
minimal level.
* Typed Scheme 2.0 extends the type system significantly, making
it more expressive. For example, predicates that are applied to
selectors, for example (number? (car x)), are meaningful to the
type system.
* Faster installation of Planet packages that trigger install of
other Planet packages, because the documentation index is
updated only once after a group of packages is installed.
* The `syntax/parse' library provides macro writers with an
enhanced syntax pattern matcher that reports errors based on the
patterns' declared classes of syntax.
* Identifier mappings following the v4 dictionary interface and
naming conventions are available from the `syntax/id-table'
library.
* Redex: added `define-relation' and generalized patterns that
appear in "where" clauses to use the full Redex pattern matcher.
(This is a backwards incompatible change, but one often
requested; see the Redex release notes for details.)
* The Web Server's serializable closures are now available for
other purposes through the web-server/lang/serial-lambda
library.
* Teachpacks: small changes to universe portion of the
"universe.ss" API, plus the addition of a form for launching
many (communicating) worlds simultaneously. Bug fixes
concerning conversion to strings.
* It is now possible to create custom scribble readers with a
command characters different than `@', see
`make-at-reader/inside' and `make-at-reader'
* Note: this is likely to be the last release that includes a
solaris distribution. If you need these builds, or if you have
access to a (Sparc) Solaris machine than can be used in PLT
builds, then please let me know.
