ANNOUNCE: Release 1.4-7 / mhvtl-2013-03-22

Mark Harvey
Release of 1.4-7 is now available.

I would like to thank everybody for their understanding during the churn of READ ELEMENT STATUS rewrite.

Bug fixes:
    - Prevent and log possibility of READ ELEMENT STATUS overflowing data buffer
    - Set 'POWERON-RESET' if library re-configured via HUP signal
    - Update 'minor' number from 'unsigned char' to 'unsigned int' which removes max number of device nodes at 256
    - Rework READ ELEMENT STATUS - Simplify code and correct bug where incorrect byte count returned.
    - Add 'support' for specifying 9x40 and DLT media via barcode suffix
    - Update kernel module to prevent overflow if DEF_MAX_MINOR_NO reached.
    - Update kernel module to allow up to 1024 minor numbers
    - Update kernel module vers to 0.18.12, vers date 20130310-0
    - off-by-one fix of compression mode page
    - Fix 'READ POSITION' ssc op code

    - Add DLT7000/DLT8000 emulation
    - Record 'last load' data in MAM
    - New utility 'edit_tape' which will allow modificiation of media 'meta data'
    - Helper scripts for NetBackup added
     - (parse 'scsi_command' output and email on tape unload)
     - (NetBackup Vault helper)

While there are updates to the kernel module, there is no requirement to install the new kernel module.
Note the one bug fixed in the kernel module with a buffer overflow if attempting to configure more than 255 tape devices.
