Some notable new things in this release are:

• Improvements to how versions are handled: We now support version (and also for the other dimension) range queries (e.g. >= v1.0.0), and we now cache Go module version queries, which makes mounting multiple versions of the same GitHub repo with different version much more practical and enjoyable, se this site and config for an annotated example.
• We finally have XMP and IPTC image metadata support, in addition to EXIF, see #13146
• Page aliases now works in multidimensional sites (e.g. multiple languages), and it is now much easier to create e.g. Netlify _redirects files that works in such setups.
• There are several performance related WebP improvements in this release.
• Also, image processing in general (e.g. resize operations) should be considerably more effective.

Breaking change

Prior to v0.155.0, alias paths beginning with a slash (/) were treated as server-relative. In v0.155.0 and later, they are now site-relative. This change only affects multilingual single-host projects that used alias paths beginning with a slash (/) to cross language boundaries. See details.

Note

• Make Page.Aliases more useful in multidimensional setups (note) ee91c70 @bep #14402
