Wagtail 5.2 (LTS) Release Candidate 1 available

[Matthew Westcott]

Hi all,

I'm pleased to announce that the first Release Candidate of Wagtail 5.2 LTS is now available! New features in this release include a redesigned page explorer listing view, support for responsive images via `<picture>` and `srcset`, formal OpenSearch support and much more. For the full lowdown, see the release notes: https://docs.wagtail.org/en/latest/releases/5.2.html

As always, we'd really appreciate you trying this out on your development / staging sites, to help us catch any issues in advance of the final release, scheduled for November 1st. To install, use `pip install wagtail==5.2rc1` or make the corresponding update in your project dependencies. For general upgrading advice, please see https://docs.wagtail.org/en/stable/releases/upgrading.html

Cheers,
- Matt
