Hello, 

The latest tarball for version 1.5 of the SpiderMonkey (JavaScript-C) engine is now available at :

           ftp://ftp.mozilla.org/pub/js/js-1.5-rc5a.tar.gz

This is Release Candidate 5a of JavaScript 1.5, containing a number of bug fixes as we progress toward a final release. A change log is available at http://www.mozilla.org/js/spidermonkey/release-notes. Here are some highlights:

http://bugzilla.mozilla.org/show_bug.cgi?id=94693
"Enhancement - way of making standard library readonly/permanent"
Implements SCOPE_IS_SEALED, JS_SealObject, JS_UnsealObject, etc. to support sealed standard object graphs.

http://bugzilla.mozilla.org/show_bug.cgi?id=174341
"JS string concatenation performance problem; memory jumps from 16 MB to 250+ MB"

Fixed sporadic, Windows-only crashes/anomalies on large integers:
http://bugzilla.mozilla.org/show_bug.cgi?id=140852   "String(819187200000) == '8191871:0000' in xpcshell, browser"
http://bugzilla.mozilla.org/show_bug.cgi?id=160602   "Large integers, e.g. getTime(), causing crash at 0x39393929"


As the various Mozilla ftp mirror sites update, the tarball will appear there. See http://www.mozilla.org/mirrors.html for a list of these sites. 

As always, you can get the most recent version of the JS engine by pulling the source code via CVS and building it locally. Details on how to do this are available at:

Sincerely,
