text: ## v0.4.0
  
  appc spec version: v0.8.5
  
  This release includes a handful of new features, improvements, and bug fixes.
  
  - stdin is now attached during run commands
  - godeps has been replaced with glide
  - a fix to allow the systemd-nspawn engine to work with systemd >= 230
  - better arm support
  - a new script mode, so acbuild can run scripts written in a special DSL
  - fixed proxy support
  - fixed isolator commands
  - added a chroot engine for the run command, so systemd-nspawn isn't needed
  
  ## v0.3.1
  
  appc spec version: v0.8.4
  
  This minor release largely exists to bump the version of the AppC spec the
  acbuild is using.
  
  - Bumps the version of the AppC spec to v0.8.4.
  - Adds the ability for acbuild to generate man pages for itself.
  
  ## v0.3.0
  
  appc spec version: v0.7.4
  
  - Sets the PATH environment variable inside of acbuild run commands, instead of
    propagating the variable from the host.
  - Copy has been split out into copy and copy-to-dir. copy is for copying a
    given file/directory to a specific path, and copy-to-dir is for copying one
    or more files/directories into a given directory.  error.
  - The run and end subcommands now contain a check for if .acbuild/target is
    mounted, and will attempt to unmount it before performing their actions.
  - The flag --working-dir has been added to the run subcommand, for specifying
    the working directory to run the given command in. This requires systemd >=
    229.
  - Added support for passing the begin command a tarball, which when not a valid
    ACI will be used as the starting rootfs for the build.
  - Now uses version 0.7.4 of the AppC spec.
  
  ## v0.2.2
  
  appc spec version: v0.7.1+git
  
  v0.2.2 is a minor release incorporating a handful of changes since v0.2.1.
  Things this release includes:
  
  - Don't require a starting character of `.` or `/` when specifying an image for
    the `--modify` flag.
  - Adds support for specifying a local directory with `begin`, for use as the
    initial rootfs of the ACI.
  - Adds support for the `run` command on systems with a version of systemd <
    209.
  - Versions of dependencies can be specified using tag syntax.
  - A bug related to the handling of hard links in tars was found, and fixed.
  - A history of acbuild commands performed is now tracked in annotations in the
    ACI being worked on. This can be disabled via a flag.
  
  ## v0.2.1
  
  appc spec version: v0.7.1+git5a7af19
  
  v0.2.0 changed the default behavior of the copy command, requiring that the
  user passed the `-T` flag to use the previous default behavior. This release
  flips that, such that the default will be as it was before, and a new flag must
  be passed to use the new behavior.
  
  ## v0.2.0
  
  appc spec version: v0.7.1+git5a7af19
  
  - Automatically fills in the `os` and `arch` labels on new builds.
  - The `--modify` flag failed to properly use an alternate work context.
  - The help page has been reformatted.
  - Extracting ACIs during begin no longer requires root.
  - Modifying an existing ACI that didn't have the `app` field set would cause an
    error.
  - Copy now has two modes of operation, toggled with the `-T` flag. The new mode
    allows copying many files at once into the ACI, as opposed to a single one.
  - When using begin with a local file, the path must now start with a `.`, `~`,
    or `/`.
  
  The following commands have been added to acbuild since the last release:
  - cat-manifest
  - isolator add
  - isolator remove
  - replace-manifest
  - set-event-handler pre-start
  - set-event-handler post-stop
  - set-working-directory
  
  ## v0.1.1
  
  appc spec version: v0.7.1+git5a7af19
  
  v0.1.1 has a couple of bug fixes since the initial release:
  
  - When the `--debug` flag was combined with the `run` command acbuild would
    panic. (https://github.com/appc/acbuild/issues/56)
  - When a remote ACI was specified with `begin`, acbuild would emit an error and
    exit after downloading the ACI. (https://github.com/appc/acbuild/pull/58)
