Since ESPN started rejecting date ranges, every scoreboard's hourly
Recent/Upcoming refresh re-asks its 22-day window (14 back, 7 ahead) one
day at a time. Measured on hdpi 2026-10-02 (NFL, college football, MLB,
college baseball, NHL): the hourly refresh was ~270 of 321 ESPN requests
and ~21 of 24.6MB in the hour. Days that ended three or more days ago
cannot change, and they were 68% of the window's bytes (6.9 of 10.2MB).
_fetch_one_chunk now keeps a settled chunk (last day <= UTC today - 3) in
memory for 24h as zlib-compressed JSON, keyed by URL, the other params
and the chunk, and answers it from there. Both range paths go through it:
fetch_espn_scoreboard and BackgroundDataService._fetch_in_date_chunks.
Each hit is parsed afresh, failed and capped chunks are not stored, and
the memory is bounded (512 entries / 8MB compressed). Against live ESPN,
a second refresh of the five hdpi windows went from 111 requests and
10.18MB to 50 requests and 3.23MB with identical events; the memory held
60 entries in 585KB.

The 3.2.0 section described the unified sports library but none of the
install-path work that landed in #428 and #431 -- which matters more than a
normal changelog omission, because the sunset rule keys on this section to
tell plugin authors what a given floor buys them.
The headline addition: 3.2.0 is the first release that *enforces*
ledmatrix_min_version. Before it the floor was advisory, so a plugin could
declare one and still be delivered to a core that could not run it. That is
the property B6 waits on, and it is now stated where a plugin author will
look for it -- along with the caveat that a core reporting below 2.0.0 is
treated as unknown rather than old and is never blocked.
Also records compatibility.py (and that it does not yet read
compatible_versions), check_release_version.py and its workflow, the
install-preservation fix, the reentrant-lock deadlock fix, and the
web_interface version re-export.
No version bump: 3.2.0 is unreleased, so this describes the release being
cut rather than a new one.
