 Description:
-NSS 3.14.3 Beta 1 with NSPR 4.9.5 Beta 2
+NSS 3.15 Beta 2 with NSPR 4.9.5 Beta 2
 
 This copy of NSS has been customized for Chromium.  NSPR is also put here
 rather than in a separate directory to emphasize the fact that Chromium is
 using NSPR strictly as an NSS dependency.
 
 We took a subset of NSS, omitting the SSL and SMIME libraries and the
 built-in root CA certificates module.  This NSS subset satisfies the
 dependencies of the NSS SSL library in src/net/third_party/nss.  Do NOT use
 this copy of NSS on platforms that have NSS as system libraries, such as
 Linux.

 Local Modifications:
 
 We made the following local changes to NSPR.
 - patches/nspr-static.patch: to build NSPR as static libraries.  See NSPR
   bug 533014 (https://bugzilla.mozilla.org/show_bug.cgi?id=533014).
 - patches/prcpucfg.h: added to the nspr/pr/include directory.
 - patches/nspr-attach-as-system-thread.patch: attach a "foreign" thread
   (a thread not created by NSPR) to NSPR as a "system" thread rather than
   a "user" thread, which needs to terminate before PR_Cleanup can return.
