gopkg.in/tools/godep.v39@v39.0.0-20151216234527-2721f686f09e/Changelog.md

# v39 2015/12/16

* Record only the major go version (ex. go1.5) instead of the complete string.

# v38 2015/12/16

* Replace `go get`, further fix up restore error handling/reporting.
    * Fixes #186
    * Don't bother restoring/downloading if already done.

# v37 2015/12/15

* Change up how download/restore works a little
    * Try to load the package after downloading/restoring. Previously
      that was done too early in the process.
    * make previous verbose output debug output
    * report a typed error instead of a string from listPackage so it can
      be asserted to provide a nicer error.

      comment as to why.
    * do *all* downloading during download phase.

# v36 2015/12/14

* Fixes #358: Using wrong variable. Will add test after release.

# v35 2015/12/11

* Fixes #356: Major performance regressions in v34

# v34 2015/12/08

# v2 2015/08/11

* Include command line packages in the set to copy

This is a simplification to how we define the behavior
of the save command. Now it has two distinct package
parameters, the "root set" and the "destination", and
they have clearer roles. The packages listed on the
command line form the root set; they and all their
dependencies will be copied into the Godeps directory.
Additionally, the destination (always ".") will form the
initial list of "seen" import paths to exclude from
copying.

In the common case, the root set is equal to the
destination, so the effective behavior doesn't change.
This is primarily just a simpler definition. However, if
the user specifies a package on the command line that
lives outside of . then that package will be copied.

As a side effect, there's a simplification to the way we
add packages to the initial "seen" set. Formerly, to
avoid copying dependencies unnecessarily, we would try
to find the root of the VCS repo for each package in the
root set, and mark the import path of the entire repo as
seen. This meant for a repo at path C, if destination
C/S imports C/T, we would not copy C/T into C/S/Godeps.
Now we don't treat the repo root specially, and as
mentioned above, the destination alone is considered
seen.

This also means we don't require listed packages to be
in VCS unless they're outside of the destination.

# v1 2015/07/20

* godep version command

Output the version as well as some godep runtime information that is
useful for debugging user's issues.

The version const would be bumped each time a PR is merged into master
to ensure that we'll be able to tell which version someone got when they
did a `go get github.com/tools/godep`.
