Boot Loader for PIC18F57K42

Hi,
I had asked about generating a boot loader for our product with PIC18F57K42 back couple of months and 
was pointed towards using MCC to generate the code for my boot loader.  However, at that time, the MCC 
had limitation on supporting this chip because this PIC18F57K42  was too big -- 128K
I was wondering if a new MCC has been released that can support generating code for PIC18F57K42?
 
The MCC  Core v4.45 is what I have.
Thanks,
Asha

    That kind of information could be in the new MCC release note.

    A new release of the MCC bootloader has been posted to www.microchip.com/mcc.  It half fixes the 7K42 128KB problem.  The main reason for the release was to update the generated code for C99 compatibility.  Also to fix the memory corruption issue for PIC16F1's when using the lower optimization levels. 
     
    The 24 bit length has been implemented on the checksum command, however the host side has not been updated to take advantage.  It's still red lit for those devices :-(   
     
    See the release notes at the same website FMI.
     
    Sorry, this update was to the generated firmware only.

    Thank you for this info.  I tried to get to the release notes but could not find it.

    If you go to https://www.microchip.com/mplab/mplab-code-configurator
    select the "Current download" tab, and the "release notes" link is right next to the "download" link.
    Scroll down to "8 bit bootloader", and the link goes to:
