+### Launcher Script
+
+One downside to manual jar downloads is that you don't keep up-to-date with the latest released version. We have a Bash launcher script at [bin/utils/openapi-generator.cli.sh](./bin/utils/openapi-generator.cli.sh) which resolves this issue.
+
+To install the launcher script, copy the contents of the script to a location on your path and make the script executable.
+
+An example of setting this up (NOTE: Always evaluate scripts curled from external systems before executing them).
+
+```
+mkdir -p ~/bin/openapitools
+curl https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/bin/utils/openapi-generator.cli.sh > ~/bin/openapitools/openapi-generator-cli
+chmod u+x ~/bin/openapitools/openapi-generator-cli
+export PATH=$PATH:~/bin/openapitools/
+```
+
+Now, `openapi-generator-cli` is "installed". On invocation, it will query the GitHub repository for the most recently released version. If this matches the last downloaded jar,
+it will execute as normal. If a newer version is found, the script will download the latest release and execute it.
+
+If you need to invoke an older version of the generator, you can define the variable `OPENAPI_GENERATOR_VERSION` either ad hoc or globally. You can export this variable if you'd like to persist a specific release version.
+
+Examples:
+
+```
+# Execute latest released openapi-generator-cli
+openapi-generator-cli version
+
+# Execute version 3.1.0 for the current invocation, regardless of the latest released version
+OPENAPI_GENERATOR_VERSION=3.1.0 openapi-generator-cli version
+
+# Execute version 3.1.0-SNAPSHOT for the current invocation
+OPENAPI_GENERATOR_VERSION=3.1.0-SNAPSHOT openapi-generator-cli version
+
+# Execute version 3.0.2 for every invocation in the current shell session
+export OPENAPI_GENERATOR_VERSION=3.0.2
+openapi-generator-cli version # is 3.0.2
+openapi-generator-cli version # is also 3.0.2
+
+# To "install" a specific version, set the variable in .bashrc/.bash_profile
+echo "export OPENAPI_GENERATOR_VERSION=3.0.2" >> ~/.bashrc
+source ~/.bashrc
+openapi-generator-cli version # is always 3.0.2, unless any of the above overrides are done ad hoc

+=== From 3.1.x to 3.2.0
+
+Version `3.2.0` is a minor version of OpenAPI-Generator, in comparison to `3.1.x` it contains some breaking changes, but with the possibility to fallback to the old behavior.
+The default value of some options might change.
+Projects relying on generated code might need to be adapted.
+
+==== Validate spec on generation by default
+
+The default is to validate the spec during generation. If the spec has errors,
+they will appear as errors or warnings to the user. This prevent generation of the project.
+
+If you want to switch back to the `3.1.x` behavior you can use:
+
+* Set the `validateSpec` option to `false` if you are using the Maven or Gradle plugin
+* Use the command line option `--skip-validate-spec` if you are using the CLI
+
+
+==== Model (all languages)
+
+In `CodegenModel` and in `CodegenOperation` we use now our own class `org.openapitools.codegen.CodegenDiscriminator` instead of `io.swagger.v3.oas.models.media.Discriminator`.
+
+For the templates, this is not an API change, because the same values are available.
+
+If you have your own `Codegen` class (to support your own generator for example) then you might get some compile error due to the change.
+
+==== Java
+
+Schema with enum values are mapped to java enum in the generated code.
+In previous version, when an unknown value was deserialized, the value was set to `null`.
+
+With `3.2.0` a new option is introduced: `useNullForUnknownEnumValue`.
+
+* When set to `false` (default value), an Exception (`IllegalArgumentException`) is thrown when the value not available in the enum.
+* When set to `true`, unknown values are mapped to `null` as it was the case in previous versions.
+
+
 === From 3.0.x to 3.1.0
 
 Version `3.1.0` is the first minor version of OpenAPI-Generator, in comparison to `3.0.3` it contains some breaking changes, but with the possibility to fallback to the old behavior.

+#### What is the difference between Swagger Codegen and OpenAPI Generator?

 #### Why was it decided to fork Swagger Codegen and to maintain a community-driven version?
 
 There are several reasons:
 
-1. The founding members came to the conclusion that Swagger Codegen 3.0.0 beta contains too many breaking changes while they strongly believe 3.0.0 release should only focus on one thing: OpenAPI specification 3.0 support.
-1. Swagger Codegen 3.0.0 beta was evaluated as unstable. Changes made directly to 3.0.0 branch without reviews or tests, were breaking the builds from time to time (e.g. a simple `mvn clean package` failed).
-1. Reviews of code changes in the 3.0.0 branch highlighted a lot of code block removal without any reason. This might produce regressions for edge cases discovered previously.
-1. Most of the test cases in the generators have been commented out as part of the migration to support OpenAPI 3.0. Test cases are the most valuable assets of the project and should be maintained to ensure a good quality.
-1. According to SmartBear, [Swagger Codegen 2.x and 3.x should be supported in parallel for a while](https://github.com/swagger-api/swagger-codegen/issues/7754#issuecomment-375039048) without the possibility to work with git branches to merge the fixes from one branch to the next. Having to implement everything twice is not a good idea and the best use of the Swagger Codegen community resources.
-1. Having a community-driven version can bring the project to the next level.
+1. The founding members came to the conclusion that Swagger Codegen 3.0.0 beta contains too many breaking changes. They also strongly believe the 3.0.0 release should only focus on one thing: OpenAPI 3.0 support.
+1. The founding members had concerns about the development practices, which seemed to be contributing to an unstable and insufficiently tested codebase.
+1. There was a disagreement on the evolutionary strategy for Swagger Codegen. The founding members felt it was important to move forward with OpenAPI 3.0 support, while maintaining backward compatibility with OpenAPI 2.0 in the same codebase.
+1. The founding members found that the enhancements and bug fixes submitted for Swagger Codegen 2.x need to be submitted again for Swagger Codegen 3.0.0 branch (otherwise, these changes would not appear in the 3.0.0 branch. Having to do the pull request twice is not the best use of community resources).
+1. The community-driven version has a more rapid [release cycle](https://github.com/OpenAPITools/openapi-generator/releases/) (weekly patch release, monthly minor release) so users do not need to wait for several months to get a stable release.
+1. Having a community-driven version _can_ bring the project to the next level with reliable releases and a clear [roadmap](https://github.com/OpenAPITools/openapi-generator/blob/master/docs/roadmap.adoc).
 
-UPDATE: After the public launch of OpenAPI Generator, some of the core team members were contacted by Ron (SmartBear) and we explained to him the reasons of the fork as explained above. We also asked him to contact team@openapitools.org if he wants to discuss further but so far we don't see any email from him to team@openapitools.org.
