PLT Scheme v4.1

PLT Scheme version 4.1 is now available from

http://plt-scheme.org/

* DrScheme changes:

- The Module language now has an automatically inserted `#lang'
declaration, so the interactions window is available right
away for new windows.

- Searching is now interactive (see the manual for details).

- Memory limits are now enabled by default.

* Typed Scheme supports a novel type checking mechanism for
homogeneous and heterogeneous variable-arity function
definitions and applications.

* Redex (a domain-specific language for testing operational
semantics) is now included in the distribution. See also
http://redex.plt-scheme.org/.

* Lots of improvement to the documentation, including: better
searching, table-of-contents, and language-sensitive help (in
the teaching languages).

* The world.ss teachpack no longer supports `end-of-time', only
`stop-when'.

* MzScheme has now a logging facility, search the documentation
for "logger" for more details.

* Bug fixes:

- `begin' in R5RS (and derived languages),

- `#lang planet',

- `eval' works with phases.

Feedback Welcome,

Is there a link with more details regarding these changes?
Like what does it mean for eval to work with phases?
Thanks!

From the release notes in mzcheme/HISTORY.txt

Version 4.1, August 2008
Changed namespaces to have a base phase; for example, calling
eval at compile-time uses a phase-1 namespace

Details on the base phase for a namespace:
