Hugo `v0.149.0`  comes with bug fixes and a set of new features/improvements, notably:

* We now build with the recently released [Go 1.25](https://tip.golang.org/doc/go1.25)
* A new [collections.D](https://gohugo.io/functions/collections/d/) template function that generates random sequences of integers using  J. S. Vitter’s Method D, by some called [The Best Algorithm No One Knows About](https://getkerf.wordpress.com/2016/03/30/the-best-algorithm-no-one-knows-about/).
* Two new [permalinks tokens](https://gohugo.io/configuration/permalinks/#tokens), `:sectionslug` and `:sectionslugs`, especially useful in multilingual Hugo projects.
* A new `--omitClassComments` flag on `hugo gen chromastyles`
* Several improvements to how ToC from Markdown gets rendered, see #13401  and #12605.
* A new `format` option in [transform.Unmarshal](https://gohugo.io/functions/transform/unmarshal/)
