2.1.0.pre.1 (August 28, 2019)

One of the biggest changes in bundler 2.1.0 is that deprecations for upcoming breaking changes in bundler 3 will be turned on by default. We do this to grab feedback and communicate early to our users the kind of changes we’re intending to ship with bundler 3. See #6965.

Another important improvement is a better coexistence between bundler installations and the default copy of bundler that comes with ruby installed as a default gem. Since bundler is shipped as a default gem with ruby, a number of users have been affected by issues where bundler ends up failing due to version mismatches, because at some point of the execution, bundler switches to run the default copy instead of the expected version. A number of PRs have been focused on minimizing (hopefully eliminating) this, such as #7100, #7137, #6996, #7056, #7062, #7193, #7216, #7274

1.0.0.rc.2 (July 29, 2010)

bundle install path was causing confusion, so we now print a clarifying warning. The preferred way to install to a path (which will not print the warning) is bundle install --path path/to/install.
bundle install --system installs to the default system location ($BUNDLE_PATH or $GEM_HOME) even if you previously used bundle install --path
completely remove --disable-shared-gems. If you install to system, you will not be isolated, while if you install to another path, you will be isolated from gems installed to the system. This was mostly an internal option whose naming and semantics were extremely confusing.
Add a --production option to bundle install:
- by default, installs to vendor/bundle. This can be overridden with the --path option
- uses --local if vendor/cache is found. This will guarantee that Bundler does not attempt to connect to Rubygems and will use the gems cached in vendor/cache instead
- Raises an exception if a Gemfile.lock is not found
- Raises an exception if you modify your Gemfile in development but do not check in an updated Gemfile.lock
Fixes a bug where switching a source from Rubygems to git would always say “the git source is not checked out” when running bundle install

NOTE: We received several reports of “the git source has not been checked out. Please run bundle install”. As far as we can tell, these problems have two possible causes:

bundle install ~/.bundle in one user, but actually running the application as another user. Never install gems to a directory scoped to a user (~ or $HOME) in deployment.
A bug that happened when changing a gem to a git source.

To mitigate several common causes of (1), please use the new --production flag. This flag is simply a roll-up of the best practices we have been encouraging people to use for deployment.

If you want to share gems across deployments, and you use Capistrano, symlink release_path/current/vendor/bundle to release_path/shared/bundle. This will keep deployments snappy while maintaining the benefits of clean, deploy-time isolation.
