Makisu Versions Save

This update contains a critical bug fix:

• v0.1.12 introduced a bug with symlinks (#288) which is fixed in this release.

This update contains mainly fixes and a couple of refactors. It is intended to be fully backwards compatible. Here are a list of some of the more important changes in this release:

• Added support for Redis username / passwords
• Correctly caching COPY --from
• Fixed pull --extract with symlinks
• Fixed parsing panic if a variable isn't defined.
• Checksum of context dir only affects the contents of the context, and is independent of its path

This release contains the following enhancements and bug fixes:

• Fix basic auth related issues
• Fixed COPY OOM errors
• Handle USER properly in the RUN command
• Handle chown params of COPY and ADD
• Adds ability to override ssl cert location with environment variable

This release contains no breaking changes. The following small fixes were added:

• Fallback option for https to http
• Fixed parameter expansion bug in example shell function (Thank you Tim Laurence)
• Chowning symlinks properly
• Checking mode of files and directories in addition to mtime
• WORKDIR now creates the target directory

In addition to this, we fixed some flaky tests, typos and updated the README.

This release contains the following minor enhancements/fixes:

• Support for push replicas (pushing with different repo names)
• Fixed registry config parsing
• Added makisu pull command
• Added support for password_file in docker's AuthConfig
• Added ability to read SSL certs from a directory

This release contains the following minor enhancements:

• Improvements to the docker credential helper usage
• Ability to use local cache if no registry config was provided
• Bug fix for flag parsing logic
• Added missing lib in alpine image

This release contains no major architectural changes, only small fixes:

• Added support for docker credential helpers
• Better logging
• Switched to using github.com/spf13/cobra for CLI
• Switched to using github.com/go-redis/redis for the Redis client library

Important Note: Previously, long flags could be used with a single - (e.g: -help). This is no longer the case, we now require a double-dash for long flag names (like --help).

A couple of minor changes:

• --registry-config can now be a JSON blob instead of just the path to the registry config
• Fix to the log output of ARG steps

This release contains no major overhauls. Below is a summary of the changes since the previous release:

• Clean up the filesystem before and after a build.
• Take relevant build options (such as the --commit flag) when calculating cache IDs.
• Handle comments properly with multi-line directives:

RUN apt-get install -y \
     # comment
     hello

Fix to cache pushing mechanism with a registry-specific configuration.
