Ext2 Installable File System 1.12
Detailed list of changes:
- Now offers support for Windows 7/8/8.1/Server 2008 R2/Server 2012/Server 2012 R2.
- Now offers support for the Windows versions for Itanium Based Systems: Windows XP, Windows Server 2003, Server 2008, and Server 2008 R2.
- Added trim support for solid state drives (SSD); Windows 7/Server 2008 R2 or higher.
- Added support for inodes which are larger than 128 bytes.
- Added support for the Ext4 dir_nlink feature.
- Added support for the Ext4 huge_file feature.
- Added support for the Ext4 uninit_bg feature, which includes group descriptor checksums.
- Support of block sizes up to 64KB has been added.
- File names that end with "~" are treated as hidden.
- The ext2fs.sys file system driver has new internals, which maintain the volume geometry; they reduce the memory consumption on very large volumes. This also adds support for the meta_bg feature and the flex_bg feature.
- The Ext4 Multiblock Allocator has been implemented; it replaces the former block allocator.
- Removed the support of the obsoleted EXT2_FEATURE_COMPAT_DIR_PREALLOC feature bit of the Ext2 file system.
- Added an integrated mountdiag implementation in the driver. It includes a new mountdiag tool which provides much more information than older versions of the Ext2 IFS software.
- Added enhanced oplocks (leasing) for SMB2.1; Windows 7/Server 2008 R2 or higher. Added directory oplocks; Windows 8/Server 2012 or higher.
- Migrated to the NX nonpaged pool memory on Windows 8/Server 2012 or higher.
- Fixed bug that caused a blue screen STOP 0xC4: DRIVER_VERIFIER_DETECTED_VIOLATION (0x3D, 0x00, 0x00, 0x00) on the x64 platform if the driver verifier is enabled.
- Fixed bug that could cause, very rarely, a blue screen upon removing a volume.
- Fixed bug that caused the computer to hang up after a Pnp unexpected removal occurred while an application was holding a file or directory handle opened.
- Fixed bug that caused an error message that write-behind data were lost upon a write attempt on a disk with insufficient space. Now the driver reports the disk full status code to the application that requested the write.
- Fixed bug that caused a thread to read corrupt data while another thread performs a non-buffered write access which causes the allocation of a block simultaneously.
- Fixed bug that failed read or write requests with a large buffer, which the native file system drivers of Windows would have done it with success.
- Fixed bug that prevented the driver from processing a create/open request which has an empty file name relative to an opened regular file. The driver returned a STATUS_OBJECT_PATH_NOT_FOUND error status code; it should have opened the relative file once more.
- Fixed bug that caused the driver not to deny create/open requests with a desired write access on a read-only file system (which is read-only due to file system features, not due to a write protected-media).
- Fixed bug that caused the driver to accidentally zero out some data of a file when it was written as memory-based file and there were concurrent file writes to the file in non-sequential manner.
- Improved the behavior with regard to data consistency when a file was used both cached and non-buffered at a time.
- Fixed bug that caused directory change notification to malfunction for the root directory of a volume; the driver issued directory change notifications with a STATUS_NOTIFY_ENUM_DIR status code without reason.
- Fixed bug which caused a performance penalty when a small cached write access appended data to a file. Often the driver prevented Fast-I/O from being used as often as possible.
- Fixed bug that, on rare occasions, caused the driver to use an already freed file object on a non-buffered read or write access. This could cause a crash of the computer.
- Fixed bug that prevented the Fast-I/O implementation of file locks from synchronizing correctly with oplocks; Fast-I/O was performed on some conditions were it shouldn't.
- Fixed bug in the ifsmount.sys driver that caused a deadlock condition upon initialization of the driver if the native mountmgr driver could not been opened.
- Fixed bug in the ifsmount.sys driver that caused a memory leak upon deletion of a drive letter.
- Fixed bug that prevented the ifsmount.sys driver from releasing some physical device objects.
- Fixed bug that prevented Windows NT Explorer and other windows to automatically update upon change of drive letters on Windows NT 4.0.

Ext2 Installable File System 1.11a
Detailed list of changes:
- Fixed bug that, on rare occasions, caused a blue screen STOP 0xD1 DRIVER_IRQL_NOT_LESS_OR_EQUAL.
- Fixed bug that prevented the Ext2 driver from updating a file's modification date when the file just was truncated (overwritten) without any subsequent writing of data.
- Fixed bug that caused a blue screen STOP 0xC2 BAD_POOL_CALLER 0x7 on Windows XP or higher upon a floppy disk change.
- A minor change that prevents a dialog box of Windows Vista and Windows Server 2008 from appearing that offers checking of an Ext2/Ext3 volume, but fails subsequently, because Windows is not able to check an Ext2/Ext3 volume.
- Fixed bug that could prevent the driver from providing all file names within a directory if the volume uses both the htree directory (dir_index) feature and UTF-8 encoding is enabled.
- Fixed bug that caused a blue screen when the Ext2 IFS 1.11 software was used together with the Truecrypt disk encryption software.
- Fixed bug that could cause the drive letters to appear immediately or after reboot even though they have been deleted.
- Fixed bug that caused loss of a drive letter upon plugging in a device when another device already occupies the same drive letter.
- Fixed bug that caused a blue screen STOP 0xC9 DRIVER_VERIFIER_IOMANAGER_VIOLATION, I/O error code 0x20E if the Windows driver verifier is enabled.
- Fixed bug that caused an "invalid parameter" error message upon setting up the software or opening the "IFS Drives" applet on the computer's control panel if there is a removable media - for example, an SD card - that has more than one partition.
- Fixed bug that could cause a "file not found" error message upon setting up the software or opening the "IFS Drives" applet on the computer's control panel.
- Now the "IFS Drives" applet window updates its contents when a volume change occurs: volume label changes, volume mounts, dismounts, lock, unlock, and dismounts. (Windows 2000 or higher.)

Ext2 Installable File System 1.11
Detailed list of changes:
- Now offers support for Windows Vista/Vista x64 and the x64 versions of Windows XP and Windows 2003 Server. Includes drivers with a digital signature for Windows Vista x64.
- UTF-8 encoding added.
- Global read-only option added.
- Support for hash indexed (htree) directories added (utilizes the so-called dir_index feature).
- New configuration components for creation and deletion of any drive letter that greatly improves the plug-n-play functionality. When a drive is removed, the corresponding drive letter is deleted. Configuration of drive letters using the Windows mountvol utility is now supported (except on Windows NT 4.0).
- File names that start with a dot "." character are treated as hidden.
- Supports GPT disks if the Windows version used also does.
- Fixed bug that, on rare occasions, caused the computer to hang up on opening of directories.
- Fixed bug that prevented the Ext2 driver from supplying the FILE_ATTRIBUTE_NORMAL attribute flag for files that lack an attribute value.
- Fixed bug that had as an effect that opening of a file or directory was not denied if its disposition information is set (delete pending).
- Fixed bug that could cause a blue screen upon removal of a drive.
- Fixed bug that had as an effect that the volume was not upgraded correctly upon writing a file larger than 2 GB.

Ext2 Installable File System 1.10c
Detailed list of changes:
- Fixed bug that prevented a volume from being dismounted if the underlying driver does not support Plug'nPlay, as is for example the case with some disk encryption drivers.
- Fixed bug that prevented a volume from being mounted if the media's sector size is 2 KB.
- Fixed bug that caused a blue screen when the underlying disk driver could not recognize the media's format, for example, upon a partially unreadable floppy disk.
- Fixed bug that could cause a blue screen on writing files; in most cases it happened when writing a file larger than 4 GB the very first time on a volume.
- Fixed bug that had as an effect that the major revision number of a revision 0 volume was not upgraded correctly to revision 1 upon writing a file larger than 4 GB.
- Fixed bug that could cause a memory leak; this bug was introduced with version 1.10b.
- Fixed bug that caused error popups upon access attempts to the raw volume of a removable drive with removed media. Such access attempts were seen on the add-on software of some external USB cardreaders.
- Fixed bug that could prevent a directory from being deleted.
- A read-only file attribute is provided for all directories and files of a volume if the volume is read-only due to a set Ext2 read-only feature bit.

Ext2 Installable File System 1.10b
Detailed list of changes:
- Fixed bug which could cause a blue screen on removing an external hot-pluggable drive, for instance, an external USB hard disk drive.
- Fixed bug that could cause a blue screen on writing files larger than 4 GBytes if the Ext2 driver was used together with some anti-virus software.
- ANSI string conversion functions have been replaced by OEM conversion functions.
- Fixed bug that prevented files containing multibyte characters in their names from being opened.
- Fixed bug that made it possible to create duplicate file names with language-specific Unicode characters in a directory.
- Fixed bug that prevented a virtual machine software from opening more than one virtual disk file.

Ext2 Installable File System 1.10a
Detailed list of changes:
- Fixed bug that, on rare occasions, caused the computer to hang up on moving files or directories.
- Fixed bug that caused a very poor write performance on external hot-pluggable drives on Windows XP, for instance external USB hard disk drives.
- Fixed bug that, under certain weird conditions, caused failing open requests with the error message "File/directory is not accessible. The filename, directory name, or volume label syntax is incorrect."
- Now a file the driver has created always has cleared "x" permissions. It inherits the "r" and the "w" permissions from the directory, where it has been created, but it no longer inherits "x" permissions from its parent directory. The behavior on creating a new directory remains unchanged: a new directory inherits all its permissions from its parent directory.
