0.138.0

Release published on the 2024-11-06 12:00:43 +0000 UTC at the url https://github.com/gohugoio/hugo/releases/tag/v0.138.0

This release soft deprecates [Page.Scratch](https://gohugo.io/methods/page/scratch/) and aliases it to [Page.Store](https://gohugo.io/methods/page/store/). The only difference between the two has been that the `Page.Scratch` was reset on rebuilds, which becomes problematic when state is written by cached content (typically `.Content`). The original motivation behind adding a new and not changing the existing method was to avoid breakage, but in hind-sight, it would have fixed more than it broke.

This release also includes a fix for a data race that I, @bep, introduced in `v0.137.0`.

## What's Changed

* Fix concurrent map read and map write in short page lookups 95e2d5beb @bep #13019 
* Alias Page.Scratch to Page.Store (note) 2c3efc810 @bep #13016
