* Update the README and Ansible metadata matrix of supported distributions for NGINX OSS and NGINX Plus.
* Update the Molecule tests to include the newly supported distributions and remove distributions that are no longer supported for NGINX OSS and NGINX Plus.
Remove the deprecation warning in the README detailing the advent of the [NGINX Core Ansible collection](https://github.com/nginxinc/ansible-collection-nginx) and the subsequent splitting from this role of the [Ansible NGINX Config role](https://github.com/nginxinc/ansible-role-nginx-config) and the [Ansible NGINX Unit role](https://github.com/nginxinc/ansible-role-nginx-unit).
* The NGINX Plus repository has been updated. This might cause some issues when running the role on an instance that already has NGINX Plus installed. **Starting with NGINX Plus R25, you will need to install NGINX Plus using release `0.20.0`. If you are trying to install R23, please use release `0.19.2`. NGINX Plus R24 should work with both release `0.19.2` and `0.20.0`.**
* The NGINX Plus modsecurity module is no longer supported by this role. Until NGINX Plus R25 is released, you might keep using release `0.19.2` if you wish to install modsecurity.
Change the url used to grep the latest NGINX version when installing from source. This should avoid the source install failing whenever the `stable` release is higher than the latest `mainline`.
* Replace Ansible community distribution with Ansible base and add the necessary extra collections as a dependency requirement. For reference, these are:
* Add `state` parameter to package module in Molecule verification tests.
* Change the command directory when running the NGINX configuration check handler to prevent edge case errors when the handler is run from a directory that the NGINX process' user does not have access to.
**The NGINX configuration functionalities included in this role have been removed as of release 0.19.0.** There now is a separate role to manage and create NGINX configurations available [here](https://github.com/nginxinc/ansible-role-nginx-config). Any new issues or PRs related to configuring NGINX should be submitted in the new NGINX configuration Ansible role repository. New issues or PRs related to configuring NGINX submitted in this repository will not be worked on.
Switch NGINX keysites and OSS default repository data from a dictionary to individual variables to prevent potential issues arisen from Jinja2 dictionary run-time evaluations.
**The NGINX Unit functionalities included in this role have been removed as of release 0.18.0.** There now is a separate role to install NGINX Unit available [here](https://github.com/nginxinc/ansible-role-nginx-unit). Any new issues or PRs related to NGINX Unit should be submitted in the new NGINX Unit Ansible role repository. New issues or PRs related to NGINX Unit submitted in this repository will not be worked on.
Implement a new syntax to specify modules to be installed. You can now use the following format if you want further fine grained control over how you install modules:
* Improve README structure and use tables where relevant.
* Update Ansible (now Ansible base) to `2.10.3`, Ansible (now Ansible Community Distribution) to `2.10.3`, Ansible Lint to `4.3.7`, Molecule to `3.1.5`, and yamllint to `1.25.0`.
* The process to install modules has changed. You will now have to use a list variable, `nginx_modules`, instead of manually setting the modules you want to install to `true` or `false`. This change will also simplify adding future supported modules to this role. You can find a list of supported modules for NGINX and NGINX Plus in [`vars/main.yml`](https://github.com/nginxinc/ansible-role-nginx/blob/main/vars/main.yml).
* Modules can no longer be added to your NGINX config using this role. Please use the [`nginx_config`](https://github.com/nginxinc/ansible-role-nginx-config) role instead.
* Changed `nginx_configure` default value from `true` to `false` to further promote the adoption of the [NGINX config](https://github.com/nginxinc/ansible-role-nginx-config) role.
*`nginx_setup_license` -- Determine whether you want to use this role to upload your NGINX license to your target host.
* The role will now fail automatically if you try to deploy NGINX from an official repository in an unsupported distribution. You can find a list of supported distributions for NGINX and NGINX Plus in [`vars/main.yml`](https://github.com/nginxinc/ansible-role-nginx/blob/main/vars/main.yml)
* Three new tags have been introduced -- `nginx_setup_license`, `nginx_install` and `nginx_check_support`.
* Add Alpine 3.12 to the list of supported platforms.
* Remove Alpine 3.8 from the list of supported platforms.
The Debian and Ubuntu repositories have slightly changed. You may run into some duplication issues when running the role on a preexisting target that already has had NGINX installed using the role. To fix this, manually remove the old repository source.
With the advent of Ansible collections and to reduce the overhead of this role, the decision has been made to split this role into three smaller roles:
* The NGINX Ansible role will keep working as is and be used to install and setup NGINX.
* There now is a separate role to manage and create NGINX configurations available [here](https://github.com/nginxinc/ansible-role-nginx-config). Any new issues or PRs related to configuring NGINX should be submitted in the new NGINX Config repository. New issues or PRs related to configuring NGINX submitted in this repository will not be worked on. The NGINX configuration functionalities included in this role will be removed in an upcoming release.
* NGINX Unit now has a separate role available [here](https://github.com/nginxinc/ansible-role-nginx-unit). Any new issues or PRs related to NGINX Unit should be submitted in the new NGINX Unit repository. New issues or PRs related to NGINX Unit submitted in this repository will not be worked on. The NGINX Unit functionalities included in this role will be removed in an upcoming release.
* The Debian and Ubuntu repositories have slightly changed. You may run into some duplication issues when running the role on a preexisting target that already has had NGINX installed using the role. To fix this, manually remove the old repository source.
* If you use `custom_options` you will now need to manually end each directive with a semicolon.
* The `status` directive is no longer supported in NGINX Plus, and the `stub_status` directive has been reworked into a template.
* The listen directive structure in the `stream` template has been updated to the listen directive structure found in the `http` template. You can now specify multiple `listen` directives in the same `server` block as well as include any extra `listen` options you might need.
* Two new variables have been introduced -- `nginx_install` and `nginx_configure` -- to let you choose whether you want to install NGINX, configure NGINX, or both.
* Molecule tests using Testinfra have been migrated to use Ansible instead.
* The role now uses `include_tasks` instead of `import_tasks` when possible to speed up the role's execution time.
* Improve configuration cleanup capabilities. You can now remove all `*.conf` files in a given directory, or specify a list of files you wish to delete.
This is a relatively minor release, but it includes a potential breaking change (hence the version bump). The one major new feature is the ability to install/build NGINX Open Source from source.
* The new listen templating options are not backwards with the previous listen templating options. Check the `README` or `molecule/template_module/playbook.yml` for examples on how to use the new listen template.
* BSD and Linux NGINX installation tasks have undergone some major changes. As such, you may have to update your playbooks accordingly.
* Module installation when using NGINX Plus has been fixed.
* Websockets templating has been reenabled after being accidentally deleted.
* When deleting your NGINX Plus license from the system, the NGINX Plus repository will also be deleted to prevent issues further down the line if you run a repository update since there will not be a license anymore to authenticate into the NGINX Plus repository.
* Role should now work correctly in distros with old versions of Python.
* Rest API configuration will now only be created when rest_api_enable is set to true (an empty file would be created in previous versions if rest_api_enable was set to false).
* Uploading/dynamically generating files should now result in the files being uploaded/created to/in the correct directory.
