----------------------------+--------------------------------
 nspr has been updated to version 4.12. This is a bug fix release:

 * added a PR_GetEnvSecure function, which attempts to detect if the
 program is being executed with elevated privileges, and returns NULL if
 detected. It is recommended to use this function in general purpose
 library code.
 * fixed a memory allocation bug related to the PR_*printf functions
 * exported API PR_DuplicateEnvironment, which had already been added in
 NSPR 4.10.9
 * several minor correctness and compatibility fixes, for the full list

 Note: I also fixed some white space issues.
