# Release notes

The following table contains release notes for the Boxever JavaScript Library.

| Version | Release notes |
| --- | --- |
| 1.4.9 | Includes the optional `web_flow_config` setting that lets you disable the asynchronous loading of the Web Experiences library (`lib.js`) and/or defer script loading until the DOM is fully built. This is facilitated through the Boxever JavaScript Library. It loads `version.js` library to get the latest version and then loads `lib.js` library. This is only for organizations that use web experiments or web experiences in Sitecore Personalize. |
| 1.4.8 | Adds compatibility with v1.3 Browser Service. Removes support for Internet Explorer 11. |
| 1.4.6 | Includes the optional `_boxever_settings.itp_cross_domain` setting, which automatically applies the cross-domain setting only for Intelligent Tracking Prevention (ITP) browsers, most commonly Safari. Also contains a bug fix for the `_boxever_settings.cookie_expiry_in_days` property to ensure the days attribute is honored for customized cookie expiry and local storage expiry. |
| 1.4.5 | If the `_boxever_settings.cross_domain` property is enabled, the `_boxever_settings.cookie_domain` is ignored. This applies to organizations that use cross-domain support, by ensuring that the browser does not reject the cookie if the domain setting does not match. |
| 1.4.4 | Removes support of the `eval()` function from the Boxever JavaScript Library. The `eval()` function runs JavaScript code represented as a string, which might be a security risk. Removes support of Internet Explorer 8. Renames the `init` property to `boxeverInit` property to avoid potential naming conflicts with other libraries. |
| 1.4.3 | Adds the `_boxever_settings.cookies_only` property that provides the option to only set cookies and disable local storage for data capture. We do not recommend this for data capture. Local storage is now only set when it is being used. Previous to version 1.4.3, the Boxever JavaScript Library bootstrapped an empty object (`{}`) in `localstorage` with the intention of being written into. |
| 1.4.2 | Adds the `_boxever_settings.cookie_expiry_in_days` property that provides the option to customize cookie and local storage expiry. |
| 1.4.1 | Supports web optimization and experiences production releases. |
| 1.3.6 | Introduces local storage to work alongside cookies for data capture. This is to account for versions of Safari 12+ with Safari Intelligent Tracking Prevention (ITP), the privacy feature that allows the Safari web browser to block cookies in Safari 12+ versions. |
