What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

This release brings a new version of the WebUI (codename NextUI), it is available in beta and can be tested alongside the existing WebUI:
- Not all features are available yet. You should check [this issue](https://github.com/gotson/komga/issues/2267) for a list of what is available and what is yet to be implemented.
- If you have any feedback/questions, or if you observe any issues, with the NextUI, please [open a discussion](https://github.com/gotson/komga/discussions/new?category=nextui-beta-test) in the dedicated category.
- You cannot refresh the page in the browser (F5 or CTR+R/CMD+R), it will load the WebUI instead

How to access the NextUI:
- from the existing WebUI, there is a link in the sidebar that will open the NextUI in a new tab
- directly from the  URL of your Komga server (ex: https://demo.komga.org/next)
