2.0.0

• Drop Rails 4.0 and 4.1 support
• Add explicit support for Rails 5 (no changes were needed)
• Use Bundler::LockfileParser to parse lockfile instead of regex (#492)

1.7.2

• Use Spring.failsafe_thread to prevent threads from aborting process due to Thread.abort_on_exception when set to true

• Specify absolute path to spring binfile when starting the server (#478)
• Time out after 10 seconds if starting the spring server doesn't work (maybe related to #480, #479)
• Prevent infinite boot loop when trying to restart the spring server due to client/server version mismatch (related to #479)

1.7.0

• Auto-restart server when server and client versions do not match
• Add spring server command to explicitly start a Spring server process in the foreground, which logging to stdout. This will be useful to those who want to run spring more explicitly, but the real impetus was to enable running a spring server inside a Docker container.
• Numerous other tweaks to better support running Spring inside containers (see https://github.com/jonleighton/spring-docker-example)

1.6.4

• Fix incompatibility with RubyGems 2.6.0.

1.6.3

• Fix problem with using Bundler 1.11 with a custom BUNDLE_PATH (#456)

1.6.2

• Fix problems with the implementation of the new "Running via Spring preloader" message (see #456, #457)
• Print "Running via Spring preloader" message to stderr, not stdout

1.6.1

• support replaced backtraces / backtraces with only line and number

1.6.0

• show when spring is used automatically to remind people why things might fail, disable with Spring.quiet = true

1.5.0

• Make the temporary directory path used by spring contain the UID of the process so that spring can work on machines where multiple users share a single $TMPDIR.

1.4.3

• Support new binstub format and --remove option

1.4.2

• Don't suppress non-spring load errors in binstub

1.4.1

• Enable terminal resize detection in rails console.

1.4.0

• Add support for client side hooks. config/spring_client.rb is loaded before bundler and before a server process is started, it can be used to add new top-level commands.
• Do not boot up the server when using -h / --help

1.3.6

• Ensure the spawned server is loaded from the same version of the Spring gem as the client. Issue #295.

1.3.5

• Fix rails test command to run in test environment #403 - @eileencodes

1.3.4

• Add rails test command.

1.3.3

• Fix yet another problem with loading spring which seems to affect some/all rbenv users. Issue #390.

1.3.2

• Fix another problem with gems bundled from git repositories. This affected chruby and RVM users, and possibly others. See #383.

1.3.1

• Fix a problem with gems bundled from a git repository, where the bin/spring was generated before 1.3.0.

1.3.0

• Automatically restart spring after new commands are added. This means that you can add spring-commands-rspec to your Gemfile and then immediately start using it, without having to run spring stop. (Spring will effectively run spring stop for you.)
• Make app reloading work in apps which spew out lots of output on startup (previously a buffer would fill up and cause the process to hang). Issue #332.
• Make sure running bin/spring does not add an empty string to Gem.path. Issues #297, #310.
• Fixed problem with $0 including the command line args, which could confuse commands which try to parse $0. This caused the spring-commands-rspec to not work properly in some cases. Issue #369.
• Add OpenBSD compatibility for spring status. Issue #299.
• Rails 3.2 no longer officially supported (but it may continue to work)

1.2.0

• Accept -e and --environment options for rails console.
• Watch config/secrets.yml by default. #289 - @morgoth
• Change monkey-patched Kernel.raise from public to private (to match default Ruby behavior) #351 - @mattbrictson
• Let application_id also respect RUBY_VERSION for the use case of switching between Ruby versions for a given Rails app - @methodmissing
• Extract the 'listen' watcher to a separate spring-watcher-listen gem. This allows it to be developed/maintained separately.

1.1.3

• The rails runner command no longer passes environment switches to files which it runs. Issue #272.
• Various issues solved to do with termination / processes hanging around longer than they should. Issue #290.

1.1.2

• Detect old binstubs generated with Spring 1.0 and exit with an error. This prevents a situation where you can get stuck in an infinite loop of spring invocations.
• Avoid warning: already initialized constant APP_PATH when running rails commands that do not use spring (e.g. bin/rails server would emit this when you ^C to exit)
• Fix reload! in rails console
• Don't connect/disconnect the database if there are no connections configured. Issue #256.

1.1.1

• Fix $0 so that it is no longer prefixed with "spring ", as doing this cause issues with rspec when running just rspec with no arguments.
• Ensure we're always connected to a tty when preloading the application in the background, in order to avoid loading issues with readline + libedit which affected pry-rails.

1.1.0

• A bin/spring binstub is now generated. This allows us to load spring correctly if you have it installed locally with a BUNDLE_PATH, so it's no longer necessary to install spring system-wide. We also activate the correct version from your Gemfile.lock. Note that you still can't have spring in your Gemfile as a git repository or local path; it must be a proper gem.
• Various changes to how springified binstubs are implemented. Existing binstubs will continue to work, but it's recommended to run spring binstub again to upgrade them to the new format.
• spring binstub --remove option added for removing spring from binstubs. This won't work unless you have upgraded your binstubs to the new format.
• config/database.yml is watched
• Better application restarts - if you introduce an error, for example by editing config/application.rb, spring will now continue to watch your files and will immediately try to restart the application when you edit config/application.rb again (hopefully to correct the error). This means that by the time you come to run a command the application may well already be running.
• Gemfile changes are now gracefully handled. Previously they would cause spring to simply quit, meaning that you'd incur the full startup penalty on the next run. Now spring doesn't quit, and will try to load up your new bundle in the background.
• Fix support for using spring with Rails engines/plugins

1.0.0

• Enterprise ready secret sauce added

0.9.2

• Bugfix: environment variables set by bundler (BUNDLE_GEMFILE, RUBYOPT, etc...) were being removed from the environment.
• Ensure we only run the code reloader when files have actually changed. This issue became more prominent with Rails 4, since Rails 4 will now reload routes whenever the code is reloaded (see https://github.com/rails/rails/commit/b9b06daa915fdc4d11e8cfe11a7175e5cd8f104f).
• Allow spring to be used in a descendant directory of the application root
• Use the system tmpdir for our temporary files. Previously we used APP_ROOT/tmp/spring, which caused problems on filesystems which did not support sockets, and also caused problems if APP_ROOT was sufficiently deep in the filesystem to exhaust the operating system's socket name limit. Hence, we had a SPRING_TMP_PATH environment variable for configuration. We now use /tmp/spring/[md5(APP_ROOT)] for the socket and /tmp/spring/[md5(APP_ROOT)].pid for the pid file. Thanks @Kriechi for the suggestion. Setting SPRING_TMP_PATH no longer has any effect.

0.9.1

• Environment variables which were created during application startup are no longer overwritten.
• Support for generating multiple binstubs at once. Use --all to generate all, otherwise you can pass multiple command names to the binstub command.
• The testunit command has been extracted to the spring-commands-testunit gem, because it's not necessary in Rails 4, where you can just run rake test path/to/test.
• The ~/.spring.rb config file is loaded before bundler, so it's a good place to require extra commands which you want to use in all projects, without having to add those commands to the Gemfile of each individual project.
• Any gems in the bundle with names which start with "spring-commands-" are now autoloaded. This makes it less faffy to add additional commands.

0.9.0

• Display spring version in the help message
• Remove workaround for Rubygems performance issue. This issue is solved with Rubygems 2.1, so we no longer need to generate a "spring" binstub file. We warn users if they are not taking advantage of the Rubygems perf fix (e.g. if they are not on 2.1, or haven't run gem pristine --all). To upgrade, delete your bin/spring and re-run spring binstub for each of your binstubs.
• Binstubs now fall back to non-spring execution of a command if the spring gem is not present. This might be useful for production environments.
• The ENV will be replaced on each run to match the ENV which exists when the spring command is actually run (rather than the ENV which exists when spring first starts).
• Specifying the rails env after the rake command (e.g. rake RAILS_ENV=test db:migrate) now works as expected.
• Provide an explicit way to set the environment to use when running rake on its own.
• The rspec and cucumber commands are no longer shipped by default. They've been moved to the spring-commands-rspec and spring-commands-cucumber gems.

0.0.11

• Added the rails destroy command.
• Global config file in ~/.spring.rb
• Added logging for debugging. Specify a log file with the SPRING_LOG environment variable.
• Fix hang on "Run bundle install to install missing gems"
• Added hack to make backtraces generated when running a command quieter (by stripping out all the lines relating to spring)
• Rails 4 is officially supported

0.0.10

• Added Spring.watch_method= configuration option to switch between polling and the listen gem. Previously, we used the listen gem if it was available, but this makes the option explicit. Set Spring.watch_method = :listen to use the listen gem.
• Fallback when Process.fork is not available. In such cases, the user will not receive the speedup that Spring provides, but won't receive an error either.
• Don't preload test_helper or spec_helper by default. This was causing people subtle problems (for example see #113) and is perhaps surprising behaviour. It may be desirable, but it depends on the application, therefore we suggest it to people in the README but no longer do it by default.
• Don't stay connected to database in the application processes. There's no need to keep a connection open.
• Avoid using the database in the application processes. Previously, reloading the autoloaded constants would inadvertently cause a connection to the database, which would then prevent tasks like db:create from running (because at that point the database doesn't exist)
• Removed ability to specify list of files for a command to preload. We weren't using this any more internally, and this is easy to do by placing requires in suitable locations in the Rails boot process (which is not explained in the README).
• Seed the random number generator on each run.

0.0.9

• Added Spring::Commands::Rake.environment_matchers for matching rake tasks to specific environments.
• Kill the spring server when the Gemfile or Gemfile.lock is changed. This forces a new server to boot up on the next run, which ensures that you get the correct gems (or the correct error message from bundler if you have forgotten to bundle install.)
• Fixed error when Spring.watch is used in config/spring.rb

0.0.8

• Renamed spring test to spring testunit.
• Implemented spring rails to replace spring [console|runner|generate].
• config/spring.rb is only loaded in the server process, so you can require stuff from other gems there without performance implications.
• File watcher no longer pays attention to files outside your application root directory.
• You can use the listen gem for less CPU intensive file watching. See README.
