Bug fix release

• Bug fixes for SEEK_DATA and SEEK_HOLE (@lesserevil and @lindig)
• Bug fixes for when the VHD chain contains different sized VHDs (@zli)

Better support for raw files

• add explicit connect to interface (@talex5)
• add tests for streaming code (@jonludlam)
• support SEEK_DATA and SEEK_HOLE (@djs55)
• fix bug walking over sector bitmaps (@jonludlam)

Add resize, parent updating

• vhd: add ability to resize (i.e. shrink) a vhd
• vhd: add ability to marshal (and hence update) a parent locator

Bugfix release

• build fixes for OS X
• fix block access after a resize

API updates, more efficient random access

• vhd: always interpret relative paths in parent locators as being relative to
  the current directory of the file containing the locator first, and then search
  the general search path after.
• deltas: handle cases where parent filenames are different strings but refer
  to the same file (e.g. "foo", "./foo")
• vhd: rename Vhd_input.hybrid -> Hybrid_input.raw
• vhd: add Hybrid_input.vhd to output vhd-formatted data
• vhd: fix stream size calculation, so progress reports (bars?) will be more accurate
• vhd: rename 'openfile' to 'openchain' to reflect that it opens an entire chain,
  or fails trying
• vhd: add 'openfile' which only opens a single file
• switch result type to a polymorphic variant
• switch Element type to a polymorphic variant
• rename the module Vhd to module F
• pack Vhd modules
• vhd: user passes in buffers to read and write, to control allocation
• vhd: write now uses the bitmap cache
• vhd: read and write now try to issue I/O in parallel (experimental)

Bugfixes for reading parent locators

We now expect the parent locators to have prefix "file://" rather than "file://./". This fixes interactions with XenServer intellicache.

read/only read/write bugfix

• always open vhd parents read/only
• allow clients to request read/only or read/write for vhd leaves

Support for old 32-bit machines

This fixes a bug preventing the opening of files > 4GiB on 32-bit machines.

Even more bugfixes

0.6.1 (2013-10-30)

• raw: use BLKGETSIZE64 to query the size if stat(2) reveals we've been given
  a block device. Otherwise we use a file size of 0 and don't copy anything.

Lots of bugfixes
