# Release notes > Every released version of Oktul Regex Field for Jira, and what changed. > > Documentation for Oktul Regex Field for Jira, for Jira Cloud, by Oktul: https://oktul.com/docs/plugins/regex-field/release-notes/ Every version that reached the Marketplace, newest first. The table is generated from the `versions` list in `src/content/apps/regex-field.md`, so this page and the product page cannot disagree about what shipped. ## 3.1.0, 21.10.2026 The first version, free on the Marketplace with every feature on every site. Two custom field types, single line and paragraph, that check every value against rules set per field context: a length, a format, the allowed characters, starts with, ends with, contains and at least N of a kind, or one regular expression. Jira applies the rules on every save, from every surface. The single-line field has strict input, which formats a value as it is typed. A field opens filled in on the create screen, the portal request form and transitions, from smart values for the person, the date, the space, the work type and other fields, Oktul Work Item Selector fields included. With **Keep in sync**, the value follows the fields it names until someone edits it, on the form, on the work item view and after a change made by Automation, a script or the REST API; `{{userInput}}` keeps the person's own words. Assets fields cannot be read yet. English and Estonian. A change to what data is collected, where it goes, or who can see it belongs here explicitly, and is also called out in the [privacy policy](./privacy/).
