<p align="center">The HDR fix from 3.0.2 now covers every format that can carry an HDR picture, the doctor explains two more reasons a thumbnail can go missing, and the right-click preview tile is back on its strict size guard.</p>

## What's changed

- **HDR HEIC, JPEG XR and TIFF thumbnails render at the right brightness.** The 3.0.2 fix for
HDR AVIF now has a proven twin for every container that can carry an HDR picture: an HDR
HEIC (PQ or HLG) takes the same path as AVIF, a linear-float JPEG XR (what Windows writes
for an HDR screenshot) is tone-mapped instead of clipped to white, and a 16-bit TIFF tagged
with a PQ profile is converted through the profile's own HDR signal rather than
colour-managed into near-black. The TIFF fix also reads a profile the decoder used to drop.
- **AVIF files with no colour box take the fast path when the codec measures right**, instead
of always going through the bundled ImageMagick, and an AVIF with a gain map or an alpha
plane is read by its main picture rather than by whichever colour box came first.
- **The right-click menu's preview tile keeps the strict size guard.** The tile that is
drawn inside Explorer itself had, since a refactor, been allowed the wider ceiling meant
for the isolated thumbnail host; it is back on the strict one, and the test that guards it
now actually reaches the codec.
- **The doctor names two more causes of a missing thumbnail.** A folder added to This PC by a
tweaker is reported, machine-wide and for the probed file (files browsed through such an
entry may never show a picture; open the real folder instead), and the per-file section now
says whether Explorer ever asked SageThumbs for that file at all, read off the diagnostics
log, so "it never reached us" no longer needs a developer to read the log by hand.
