We’ve decided to sunset synchronous containers and synchronous tags by October 7, 2024.
Our research shows that users rarely install these containers or use synchronous tags, and most use cases can be replaced with asynchronous tags. Additionally, some browsers have started to issue warnings regarding the use of synchronous tags, particularly in the context of blocking code in the head section. This suggests that synchronous tags may become unsupported in the future, potentially disrupting functionality for websites relying on them.
By sunsetting synchronous containers and tags, we aim to streamline web development practices, promote more efficient loading strategies and encourage the adoption of modern, non-blocking techniques that align with evolving web standards and best practices.
If you use synchronous containers and tags, we recommend the following:
- Remove synchronous tags and replace them with asynchronous ones. In most cases, you can easily transition to alternative methods to achieve similar functionality.
- Remove synchronous containers as they affect the performance of your website.
Synchronous containers and tags will stop working by October 7, 2024.
