Rails LTS Show archive.org snapshot has been conceived as a drop-in replacement for Rails 2.3, 3.2, and 4.2. However, we do recommend that you go through the list below to make sure that installing Rails LTS will work without problems.
Rails 2.3 LTS
Rails version
Your application should run the latest release of the official Rails 2.3 gems.
If you are running an earlier version, we strongly recommend upgrading to Rails 2.3.18 before installing Rails LTS.
Ruby version
Rails 2.3 LTS works with Ruby 1.8.7 out of the box.
We also support Ruby 2.5, Ruby 2.7, Ruby 3.1, and Ruby 3.3, however upgrading your Ruby version involves some manual steps.
We do not support Ruby 1.9 for 2.3 LTS.
RubyGems version
Rails 2.3 LTS requires RubyGems < 2. We recommend the latest 1.x release, which is 1.8.30 at the time of writing.
If you are using Rails 2.3 LTS with bundler you can also use current RubyGems versions.
ActiveRecord Database
Your ActiveRecord models should talk to one of the following databases:
- MySQL (version 5.6)
- PostgreSQL
- SQLite3
While other database types might work with Rails 2.3 LTS, we only test against the databases listed above.
Rails 3.2 LTS
Rails version
Your application should run the latest release of the official Rails 3.2 gems.
If you are running an earlier version, we strongly recommend upgrading before installing Rails LTS.
Ruby version
Rails 3.2 LTS is tested against the following Ruby versions:
- Ruby 1.8.7
- Ruby 1.9.3
- Ruby 2.3
- Ruby 2.5
- Ruby 2.7
- Ruby 3.1
- Ruby 3.3
While other Rubies might work with Rails LTS, we only test against the versions listed above.
Rails 4.2 LTS
Rails version
Your application should run the latest release of the official Rails 4.2 gems.
If you are running an earlier version, we strongly recommend upgrading before installing Rails LTS.
Ruby version
Rails 4.2 LTS is tested against the following Ruby versions:
- Ruby 2.1
- Ruby 2.3
- Ruby 2.5
- Ruby 2.7
- Ruby 3.1
- Ruby 3.3
While other Rubies might work with Rails LTS, we only test against the versions listed above.
Rails 5.2 LTS

Your application should run the latest release of the official Rails 5.2 gems.
If you are running an earlier version, we strongly recommend upgrading before installing Rails LTS.
Ruby version
Rails 5.2 LTS is tested against the following Ruby versions:
- Ruby 2.2
- Ruby 2.5

Rails 6.1 LTS

Ruby version
Rails 6.1 LTS is tested against the following Ruby versions:
- Ruby 2.5
- Ruby 2.7
- Ruby 3.1
- Ruby 3.3
While other Rubies might work with Rails LTS, we only test against the versions listed above.
Bundler version
Make sure that you have Bundler Show archive.org snapshot 1.11 or newer by running:
gem list | grep bundler
This should show you a line like this:
bundler (1.11.2)
If your version is lower than 1.11
, you can should update Bundler.
If you are using Ruby 1.8.7 make sure that you install the latest compatible version:
gem install bundler --version=1.13.7
If you are using Ruby 2, you can install the latest version of Bundler:
gem install bundler
Please note that you need to have a compatible version of Bundler on all PCs that will be running your application (developer boxes, production servers, staging servers).
ActiveRecord Database
Your ActiveRecord models should talk to one of the following databases:
- MySQL
- PostgreSQL
- SQLite3
While other database types might work with Rails LTS, we only test against the databases listed above.
All set?
If your application satisfies the requirements above, you should now subscribe to Rails LTS Show archive.org snapshot and upgrade your application.
