Release Notes for Ext2Fsd V0.61
==================================
Features implemented or bugfix since V0.53:
1, Ext4 extent writing support (developed by ngkaho1234 @ gmail.com).
See his repository for more details:

extent-based mappings
3, 16T volume supported (tested with 4T volume / 4K block-size)
Version 0.53 and previous versions only support up to 2T volume
ticket: https://sourceforge.net/p/ext2fsd/bugs/134/
4, Deletion acceleration: truncation optimized for indirect-based files
5, Size-expanding disabled in IRP_MJ_CREATE for better performance.
Windows sometimes would truncate file size back to 0

created but not yet written
13,Renaming supported: with names only diffs in lower or upper cases
