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
• A new 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.
• Two new 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
