POST /api/v3/config/dim-schedule with {"dim_brightness": Infinity} answered
500. So did /api/v3/errors/clear with max_age_hours, and /api/v3/config/main
with multiplexing or row_address_type.
json.loads accepts Infinity/-Infinity/NaN by default -- they are not valid
JSON, but Python's parser emits them -- and Flask's get_json passes them
straight through. int(float('inf')) raises OverflowError, which is neither
ValueError nor TypeError, so validation blocks that carefully caught those let
it past and Flask turned it into a 500.
The status code was not the real damage. dim-schedule answered with
CONFIG_SAVE_FAILED and suggested "Check file permissions on config directory"
and "Check available disk space" for what was an invalid number. Every one of
these sites already had a correct 400 response written; they just never
reached it.
NaN already returned 400, because int(nan) raises ValueError. That is why this
only ever showed up for the infinities, and why it survived: the obvious test
case passes.
OverflowError is now caught alongside ValueError/TypeError at the 27 sites in
this file whose try block performs a numeric coercion. An AST sweep confirms
no int()/float() of request-derived data is left outside a block that catches
it.
Verified end to end through Flask's test client rather than by reasoning about
the parser: all four routes returned 500 before and 400 after.
Tests: five Infinity cases (which fail against the previous except tuples),
two NaN cases pinned so narrowing the tuple cannot quietly break them, and a
check that ordinary input is not rejected by the widened guard.

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.
