Reviewable status: 3 unresolved discussions, needs platform reviewer assigned, needs at least two assigned reviewers, commits need curation (https://drake.mit.edu/reviewable.html#curated-commits) (waiting on rpoyner-tri).

doc/_release-notes/v1.52.0.md line 21 at r1 (raw file):

   * GCC >= 13 ([#24232][_#24232])
   * Clang >= 20 ([#24232][_#24232], [#24275][_#24275])
   * Apple LLVM >= 17 (Xcode >= 26.3) ([#24232][_#24232])

nit this is not new as documented, unless you wanted to announce the fix in CMakeLists.txt to make the build warn. I'm not sure I see the gain.

However, per my other thread, up to y'all to decide whether something like "Apple LLVM >= 21 (Xcode 26.4)" on macOS Tahoe only is worth a mention up here.

doc/_release-notes/v1.52.0.md line 25 at r1 (raw file):

   * fmt >= 9.1 ([#24223][_#24223])
   * spdlog >= 1.12 ([#24223][_#24223]).
* As previously announcted, Drake is switching to a new AutoDiff implementation

nit typo

Suggestion:

As previously announced

doc/_release-notes/v1.52.0.md line 207 at r1 (raw file):

* Update supported Clang on Ubuntu to 20 ([#24275][_#24275])
* Update supported macOS CMake to 4.3 ([#24277][_#24277])
* Update supported macOS Xcode to 26.4 ([#24277][_#24277])

nit clarity

Suggestion:

Update supported Xcode on macOS Tahoe to 26.4

Yes, this is announcing the new minimum bar, as expressed in the warning. Same as the GCC >= 13 and Clang >= 20 immediately above.

New features

* Allow CENIC to accept nested diagrams ([#24207][_#24207])

BTW Do we want to say CENIC or CenicIntegrator?

Ditto throughout.

* Add some build dependencies to our apt package release ([#24399][_#24399])

These are in the wrong spot. I'll push a fix.

doc/_release-notes/v1.52.0.md line 53 at r15 (raw file):

  * `fmt_eigen` now also supports `fmt`'s range format specs "s", "?s", and "n".
  * Consider these changes in code that uses `fmt_eigen`:
    * Remove brackets from hand-written format strings surrounding a formatted

BTW Maybe this might not be obvious, but any invocation of fmt::to_string(fmt_eigen(foo)) would have to change to fmt::format("{:#}", fmt_eigen(foo)) if they want to restore the original formatting.

The fact that fmt::to_string doesn't support the formatting that fmt::format does might be a point of friction.

hm, these Jammy release artifacts won't exist. Is the base of this branch outdated?

Master doesn't have any novel fixes here. This is just a line that we need to delete by hand in the first release that doesn't have Jammy, which is this one.
