Ext2Fsd 0.61 was released !

Features implemented or bugfix since V0.53:
    1, Ext4 extent writing support (developed by ngkaho1234 @ gmail.com)
       See his repository for more details:
       http://github.com/ngkaho1234/Ext3Fsd.git
    2, Size manipulation and i/o path revised for support of indirect and
       extent-based mappings
    3, 16T volume supported (tested and confirmed with 4T volume)
       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
    6, Support Volume exclusive-open for e2fsprogs utils. Any attempts
       will be denied while EXT4 volume is being checked (e2fsck).
    7, FIXME:  Possible zero-content returned (requesting data from file tail)
    8, FIXME:  File ByteOffset updated for FO_SYNCHRONOUS_IO open (async i/o)
       ticket: https://sourceforge.net/p/ext2fsd/bugs/133/
    9, FIXME:  don't do byte or range round up for paging i/o requests
       ticket: https://sourceforge.net/p/ext2fsd/bugs/129/
   10, FIXME:  occasional block bitmap difference issue, cased by checksum
               caculation in uninit_bg group initializing
   11, e2fsprogs utils for Windows (e2fsck, mke2fs, tune2fs, debugfs) included
       [the followings are change-logs made upon V0.60]
   12, FIXME: Ext4 unwritten-extent supported to avoid possible data corruption
              MSB of ee_len field of unwritten extent is used as only a flag. It
              was mistakenly treated as extent length (block numbers) in V0.60
   13, FIXME: Manually clear file to zero for indirect-block file that is newly
              created but not yet written
   14, Renaming supported: with names only diffs in lower or upper cases
   15, I/o path revised to correctly handle ValidDataLength & unwritten holes

    1, flexible inode size: > 128 bytes, up to block size
    2, dir_index:    htree directory index
    3, filetype:     extra file mode in dentry
    4, large_file:   > 4G files supported
    5, sparse_super: super block backup in group descriptor
    6, uninit_bg:    fast fsck and group checksum
    7, extent:       full support with extending and shrinking.
    8, journal:      only support replay for internal journal
    9, flex_bg:      first flexible metadata group
Unsupported Ext3/4 features:
    1, journal: log-based operations, external journal

    I’m curious to find out what blog system you happen to be using?

    I’m having some minor security issues with my latest blog and I would like to find
    something more safeguarded. Do you have any solutions?
