Release notes

We try to reduce backwards compatibility breakage only to major version releases, i.e. X.0.0. Minor releases (1.X.0) may include new features, whereas patch releases (1.0.X) will generally be used to fix bugs. Not all versions have followed these simple rules to date (and sometimes new features may creep up in patch releases), but we try to adhere them as much as possible :).

Release history

4.0.0 (unreleased)

This release contains some major improvements in the API of imagemounter, making large if-statements obsolete and obtaining more ‘Pythonic’ code where possible. It is a continuation of the efforts in version 3.0 and includes fixes from many contributors.

New features:

  • Allowed programmatic access to dependency checks (contributed by gtback). This enables you to write code that checks whether certain dependencies are satisfied.

  • Changed the way file system types work. Large if-statements in the code have been replaced by class-based filesystem types. Backwards incompatible: the fstype property is no longer a string, but a class instead.


    This change may result in file systems that were previously correctly detected suddenly not being identified correctly. If you encounter such an error, please submit a bug report stating the outputs of the different identifiers, the actual result and the expected result. You can obtain this information using -vvvv on the command line.

  • Add support for VBox disk images (vdi) (contributed by ruzzle)


  • Renamed nbd to qemu-nbd (contributed by Jarmo van Lenthe)
  • Support for segmented filenames higher than 999 (contributed by jdossett)
  • Fixed xmount command order (contributed by Jarmo van Lenthe)

3.1.0 (2017-08-06)

New features:

  • Support for exFAT filesystems (contributed by ldgriffin)
  • Addition of force_clean method to ImageParser
  • Addition of --skip, to complement --only-mount
  • Improved support for UFS / BSD volumes


  • Updated --keys to not parse commas (as these may be part of the key themselves) and properly support the asterisk key.
  • Several fixes for fsstat call, including actually killing it after 3 seconds and optimizations by passing in the correct FS type, making mounting actually a lot faster.
  • Fixes for path expanding (contributed by ruzzle)
  • Re-index loopbacks prior to unmounting in the Unmounter class (contributed by ldgriffin)
  • Use --sizelimit for various mounts, for support in newer kernel versions (contributed by ldgriffin)
  • Improved support for non-ASCII volume labels
  • The parted detection method does not hang anymore when parted requests input
  • Fix for communication of LUKS keys to the cryptsetup command
  • Fixes for reconstruction when multiple roots exist

3.0.1 (2017-04-08)

  • Add support for qcow2 (contributed by Jarmo van Lenthe)
  • Allow use of lowercase e01 file extension when mounting a directory in imount CLI (contributed by sourcex)
  • Add ADS support for NTFS volumes (contributed by Patrick Leedom)
  • Ability to lazily call fusermount -uz when unmounting (contributed by Patrick Leedom)
  • Fix regression in mounting LV volumes; the path was incorrectly detected in get_raw_path() for these volumes.
  • Fix regression in detection of single volumes that would be detected as DOS/MBR based on file type.

3.0.0 (2016-12-11)

This new release includes several backwards-incompatible changes, mostly because features were removed from the public API or have been renamed to obtain a more consistent API.

It was released after a long time of development, and does not even contain all features that were originally planned to go into this release, but it contains some important bugfixes that warranted a release.

New major features:

  • Add volume shadow copy support for NTFS
  • Add BDE (Bitlocker) support
  • Addition of --keys CLI argument and corresponding argument to Volume class, allowing to specify key material for crypto mounts, supporting both BDE and LUKS.
  • (Experimental) support for volume systems inside a volume. This is useful when e.g. a LVM volume contains in itself a MBR.
  • A split between detection and initialization of volumes has been made. The basic way to access volumes as calling init(), but that mounted all volumes immediately. Now, detect_* methods have been added.
  • Support blkid to retrieve FS type info
  • Support for Linux RAID volumes
  • (Still in development) interactive console, which will eventually become the primary means to interact with imagemounter.


  • Calling init() will not automatically mount the volume when it is not alloc.
  • Fix a bug where .e01 files (lowercase) would not be recognized as Encase
  • Fixed support for newer versions of mmls
  • Fixed support for pytsk3 under Python 3 (contributed by insomniacslk)
  • Fixed support for EnCase v7 (EX01) image files (contributed by pix)
  • Improved detection of several volume types
  • index is now always str
  • Volume.size is now always int
  • Improved the unmounter with generic loopback support

Removed and modified features:

  • Stopped providing None and False results when things go wrong for most methods. Instead, numerous exceptions have been added. These exceptions should be catched instead, or when using mount_volumes or init, you can specify swallow_exceptions (default) to restore previous behaviour. This is useful, since iteration will continue regardless of exceptions.
  • Moved the attributes fstypes, vstypes, keys, mountdir and pretty to the ImageParser instance, so it does not need to get passed down through the *args hack anymore. For instance, fstypes has been moved; the dict will be inspected upon Volume instantiation and stored in the fstype attribute. Other arguments and attributes have been eliminated completely, or have been replaced by arguments to specific methods.
  • Added an intermediary class VolumeSystem. Both Volume and Disk now use this (iterable) base class in their volumes attribute. If you relied on volumes being a list, you should now use list(volumes). If you relied on indexing of the attribute, you could now also use disk[0] or volume[0] for finding the correct volume index. volume_source was moved to this class, as have vstype and volume_detector.
  • Changes to the CLI:
    • Removed --fsforce and --fsfallback. Use * and ? as fstypes instead for the same effect. This should make the CLI more sensible, especially regarding the --fsforce argument. The default FS fallback is still unknown, which can only be overridden by specifying --fstypes=?=none. (You can now specify --fstypes=TYPE, which equals to --fstypes=*=TYPE)
    • Removed --stats and --no-stats. These only complicated things and fsstat has been working fine for years now.
    • Removed --raid and --no-raid (due to Volume RAID support)
    • Removed --disktype and --no-disktype.
    • Renamed --method to --disk-mounter.
    • Renamed --detection to --volume-detector.
    • Renamed --vstype to --vstypes, now accepting a dict, similar to --fstypes
    • Moved the file into a new cli module, where also a new experimental shell-style CLI is under development.
  • Changes specific to ImageParser:
    • Added add_disk and made paths optional in constructor.
    • Added indexing of the ImageParser and added get_volume_by_index method.
    • Removed mount_single_volume and mount_multiple_volumes. Use init_volumes instead, or use a custom loop for more control.
    • Dropped support for a single string argument for paths in __init__. Additionally, dropped the paths attribute entirely.
  • Changes specific to Disk:
    • Renamed method to disk_mounter (see also CLI)
    • Removed name, avfs_mountpoint and md_device from public API.
    • Removed Linux RAID Disk support. Instead, mount as a single volume, with the type of this volume being RAID. This greatly simplifies the Disk class. (This means that loopback has also been dropped from Disk)
    • Added detect_volumes method, which can be used to detect volumes.
    • Removed most mount_* methods. Moved mount_volumes to init_volumes. Functionality from the other methods can be restored with only a few lines of code.
    • Removed the need for the rather obsure multifile attribute of mount. Only xmount actually required this, so we just implicitly use it there.
    • Moved the type attribute to a method get_disk_type.
  • Changes specific to Volume:
    • Renamed get_raw_base_path to get_raw_path
    • Renamed get_size_gib to get_formatted_size
    • Removed get_magic_type, fill_stats, open_jffs2, find_lvm_volumes and open_luks_container from public API.
    • Removed the *_path, carvepoint and bindmountpoint attributes from the public API. For carvepoint, the carve method now returns the path to the carvepoint. All data has been moved to the private _paths attribute. The mountpoint and loopback attributes are kept.
    • Removed fsforce and fsfallback arguments and attributes from Volume (see also CLI)
    • Added init_volume, which only mounts the single volume. It is used by init and the preferred way of mounting a single volume (instead of using mount)
    • Moved several attributes of Volume to a new info attribute, which is publicly accessible, but its contents are not part of a stable public API.
  • Changes specific to VolumeSystem (if you consider it on par with the functionality moved from Disk):
    • Renamed detection to volume_detector (see also CLI)
    • Added a VolumeSystem.detect_volumes() iterable, which is the basic functionality of this class.
    • Moved mount_single_volume code from Disk to this class, adding the single volume detection method. The directory detection method has been incorporated in this new method.
  • Dropped support for Python 3.2, since everyone seems to be doing that these days.
