What do you want to do?

• [ ] Request a change to existing documentation
• [ ] Add new documentation
• [X] Report a technical problem with the documentation
• [ ] Other

Tell us about your request. Provide a summary of the request and all versions that are affected. We've got users that are unsure if they can use different features field types based on their availability in OpenSearch. All of these types should have version information such as Introduced in OpenSearch 2.5

What other resources are available? Provide links to related issues, POCs, steps for testing, etc. https://opensearch.org/docs/latest/field-types/supported-field-types/index/

Thanks for adding this issue, @peternied. The best way to find out if a field type is available in a version is to open the archived documentation for that version. Since we started to only update only the latest version of the documentation (currently 2.13), when we introduce something new, we add the 'introduced' label. But since we do have a record of when something was included (in the archived docs and also release notes) we won't go back and identify in which version something was introduced. However, if someone would like to take it on, we would welcome the contribution!
