Bhaskar just announced this on several mailing lists...

V6.0-001 brings a number of useful enhancements to GT.M. For example:

An environment variable to provide an initial value to $ETRAP at process startup, overriding the default $ZTRAP="B", which in the event of a buggy application error trap can drop the process to direct mode, undesirable behavior in production

Significantly speed-up a common type of indirection, of the form @x@(), where the subscripts vary with each invocation

For the symmetric cipher, demonstrating support in the encryption plugin for both libgcrypt and OpenSSL, and with the latter, a choice of AES CFB and Blowfish CFB as the cipher

On Linux, an option to use huge pages, for those applications that can benefit from a significant reduction in the use of virtual memory page tables

The new MUPIP SIZE command with a choice of techniques to rapidly estimate global variable size

For application code that uses, or may use, side-effects in ways where order of evaluation matters, an option to direct the compiler to generate object code with strict left to right evaluation, bypassing certain optimizations that can reorder evaluation

New functionality in utility programs, for example, the LOOP^%XCMD entryref to facilitate filters in GT.M, where one might otherwise use the UNIX awk utility

A new $ZWRITE() function to return a string with non-graphic characters represented in the $CHAR() format produced by the ZWRITE command

There are numerous other enhancements, improvements to ease of use and robustness, and bug fixes as described in the release notes ( ... Notes.html for html - for all current GT.M user documentation, including the release notes in PDF, go to and click on the User Documentation tab).
Please do try V6.0-001 and let us know what you think. Thank you for your continued use of GT.M.
