From this release we don't use external Boehm GC library because
gauche needs GC to be built with special compilation options.
New features in 0.8.6:
* New modules:
+ dbi: Database independent access layer, providing unified
access to various relational databases. You need separate
"driver" packages to access the actual RDBMS. There are a
few driver packages available at
http://www.kahua.org/cgi-bin/kahua.fcgi/kahua-web/show/dev/DBI/.
Note: If you have been using the separate dbi module, make
sure you remove it before using the new dbi and dbd
modules. You can find the old dbi.scm under somewhere like
/usr/local/share/gauche/site/lib (the actualy directory
depends on the configuration when you've installed the dbi
module).
+ util.relation: A framework to work with relations (as defined
by Codd). The result of database access via dbi is represened as
a relation.
+ text.sql: SQL parser/constructor. Full features are not
implemented yet, but used in dbi module for prepared queries.
* New SRFIs:
+ SRFI-40 (Library of streams) as util.stream.
+ SRFI-43 (vector library) as srfi-43.
+ SRFI-45 (Primitives for Expressing Iterative Lazy
Algorithms) : built-in.
* New built-in proceduers global-variable-bound? and
glboal-variable-ref. The former supersedes symbol-bound? (
symbol-bound? is now deprecated and will go away in the future
releases. Code that uses symbol-bound? should change it to
global-variable-bound?. ). The latter removes some need of using
eval just to peek the value of the global variable.
* New regexp procedures: regexp-replace*, regexp-replace-all*,
regexp-case-fold?.
* Stack overflow handling is largely improved. You can see better
performance if your script frequently oveflows the stack.
0.8.5 was a maintainance release.
0.8.4:
Gauche 0.8.4:
The compiler and VM have been rewritten. Now Gauche runs faster with
less memory (as fast as 1.9x, or cosumes 0.7x memory, in best cases of
our tests. But your mileage may vary.) The compiler now does simple
closure optimization, so the typical loop-by-local-closure style code
will get the advantage. On the other hand, you won't see much gain in
OO-heavy or library-heavy programs.
Other changes:
* New features:
+ srfi-42 (Eager comprehension) is supported.
+ srfi-55 (require-extension) is supported.
+ A simple sampling profiler is implemented to help tuning
programs. Check out "Profiling and tuning" section of the
reference manual. The profiler may not be available on all
platforms.
+ We provide an experimenal Windows/MinGW binary package for
the convenience. See download page.
