Migrate your server with confidence!" --- # PSPDFKit for Web 2022.4 migration overview [PSPDFKit for Web 2022.4](https://www.nutrient.io/blog/pspdfkit-web-2022-4-media-annotations/) introduces some new APIs and includes several bug fixes. We recommend verifying your implementation to check if it needs updating. ## Notable changes This is the last release of PSPDFKit for Web that still includes support for Internet Explorer 11. As of this version, IE11 support is officially deprecated, and running PSPDFKit for Web 2022.4 in IE11 will show a warning. As of version 2022.5.0, IE11 won’t be supported. With this change in supported browsers, we’ll be able to focus our efforts on optimizing the Web SDK and adding new functionality by reassigning resources that were needed to keep IE11 support. We’ll also be able to explore how to benefit from modern APIs and features only found in modern browsers. ## Migrate PSPDFKit Server For more information, take a look at the [PSPDFKit Server 2022.4 migration guide](https://www.nutrient.io/guides/product-archives-and-deprecated-solutions.md). --- ## Related pages - [1 1](/guides/web/release-notes/1-1.md) - [1 11](/guides/web/release-notes/1-11.md) - [1 0](/guides/web/release-notes/1-0.md) - [1 10](/guides/web/release-notes/1-10.md) - [1 12](/guides/web/release-notes/1-12.md) - [1 13 1](/guides/web/release-notes/1-13-1.md) - [1 16](/guides/web/release-notes/1-16.md) - [1 13](/guides/web/release-notes/1-13.md) - [1 2](/guides/web/release-notes/1-2.md) - [1 14](/guides/web/release-notes/1-14.md) - [1 3](/guides/web/release-notes/1-3.md) - [1 15](/guides/web/release-notes/1-15.md) - [1 4](/guides/web/release-notes/1-4.md) - [1 5](/guides/web/release-notes/1-5.md) - [1 6](/guides/web/release-notes/1-6.md) - [1 7](/guides/web/release-notes/1-7.md) - [1 9](/guides/web/release-notes/1-9.md) - [1 8](/guides/web/release-notes/1-8.md) - [2017 3](/guides/web/release-notes/2017-3.md) - [2017 6](/guides/web/release-notes/2017-6.md) - [Update your PSPDFKit for Web to version 2017.7](/guides/web/release-notes/2017-7.md) - [Explore new features in PSPDFKit for Web 2017.9](/guides/web/release-notes/2017-9.md) - [Upgrade annotations in PSPDFKit Web 2017.8](/guides/web/release-notes/2017-8.md) - [Discover the new features in PSPDFKit for Web 2018.3](/guides/web/release-notes/2018-3.md) - [PSPDFKit for Web 2018.2 migration insights](/guides/web/release-notes/2018-2.md) - [Explore PSPDFKit for Web 2018.4 features](/guides/web/release-notes/2018-4.md) - [New features in the 2018.1 migration guide](/guides/web/release-notes/2018-1.md) - [Explore PSPDFKit for Web 2018.6 enhancements](/guides/web/release-notes/2018-6.md) - [Explore new features in PSPDFKit 2018.5](/guides/web/release-notes/2018-5.md) - [Explore the new features in PSPDFKit 2018.7](/guides/web/release-notes/2018-7.md) - [Key updates in PSPDFKit for Web 2019.1](/guides/web/release-notes/2019-1.md) - [PSPDFKit for Web 2019.3 migration highlights](/guides/web/release-notes/2019-3.md) - [2019 2](/guides/web/release-notes/2019-2.md) - [Essential updates in PSPDFKit for Web 2019.4](/guides/web/release-notes/2019-4.md) - [PSPDFKit for Web 2019.5 migration insights](/guides/web/release-notes/2019-5.md) - [Upgrade to PSPDFKit Web 2020.3 seamlessly](/guides/web/release-notes/2020-3.md) - [Unified CRUD API enhancements for easy migration](/guides/web/release-notes/2020-5.md) - [Seamless migration to PSPDFKit for Web 2020.2](/guides/web/release-notes/2020-2.md) - [Key changes in PSPDFKit for Web 2020.1](/guides/web/release-notes/2020-1.md) - [PSPDFKit Web and Server 2020.4 migration update](/guides/web/release-notes/2020-4.md) - [Seamlessly migrate to PSPDFKit for Web 2021.2](/guides/web/release-notes/2021-2.md) - [Upgrade to PSPDFKit for Web 2021.1 with ease](/guides/web/release-notes/2021-1.md) - [PSPDFKit Web 2020.6 migration insights](/guides/web/release-notes/2020-6.md) - [2021 3](/guides/web/release-notes/2021-3.md) - [Migration guide for PSPDFKit 2021.5](/guides/web/release-notes/2021-5.md) - [PSPDFKit 2021.4 migration guide for seamless updates](/guides/web/release-notes/2021-4.md) - [PSPDFKit 2022.1.1 migration changes](/guides/web/release-notes/2022-1.md) - [2021 6](/guides/web/release-notes/2021-6.md) - [Enhancements in PSPDFKit for Web 2022.2](/guides/web/release-notes/2022-2.md) - [Explore the new features of PSPDFKit for Web 2022.3](/guides/web/release-notes/2022-3.md) - [Key improvements in PSPDFKit for Web 2022.5](/guides/web/release-notes/2022-5.md) - [Discover the key updates in PSPDFKit for Web 2023.1](/guides/web/release-notes/2023-1.md) - [PSPDFKit 2023.2 migration and updates](/guides/web/release-notes/2023-2.md) - [Key updates in PSPDFKit for Web 2023.3](/guides/web/release-notes/2023-3.md) - [Key updates in PSPDFKit for Web 2023.5](/guides/web/release-notes/2023-5.md) - [Explore key updates in PSPDFKit for Web 2023.4](/guides/web/release-notes/2023-4.md) - [2024 7](/guides/web/release-notes/2024-7.md) - [2024 3](/guides/web/release-notes/2024-3.md) - [2024 2](/guides/web/release-notes/2024-2.md) - [2024 5](/guides/web/release-notes/2024-5.md) - [Upgrading Nutrient Web SDK](/guides/web/release-notes/upgrading.md) - [2024 4](/guides/web/release-notes/2024-4.md) - [2024 8](/guides/web/release-notes/2024-8.md) - [Essential Nutrient Web SDK 2024.1 migration tips](/guides/web/release-notes/2024-1.md)
