Severity: moderate

Justification: Range adds a new Reduction feature in hardware (#163) and fixes a non-zero width mismatch for VCS simulation, both RTL-affecting. Includes VCS-elab fixes + collective-routing bug fixes + chimney output cuts (#169), and a floogen collective-check on the model (#181). Two v0.8.x point releases. Not architectural enough to be major, but more than docs/CI.

What changed (highlights)

• Reduction feature (hw) — new on-chip reduction support (core_et: rf_latch_* register-file family unmapped to FakeRAM — bloats synth runtime + instance count #163).
• VCS elab fixes + collective-routing bug fixes + chimney output cuts (update-results skill: data-leaves convention; drop hardcoded portfolio mapping #169) — bundle of correctness fixes.
• floogen endpoint RDL exclusion (#178) — allow excluding endpoints from generated RDL.
• floogen collective check on the model (#181).
• Non-zero width mismatch fix for VCS simulation (#179).
• Docs — bump zensical; improve mkdocstrings integration (liteeth: rename target to liteeth (was liteeth_udp_usp_gth_sgmii); collapse parent/child packages #170).
• License / housekeeping — migrate to REUSE for license handling (update-results skill: emit per-(platform, variant) placeholders for ALL missing slots #167); bump gitlab-ci action (sky130hd/litepci: route-fix via spread lever (util 30 / density 0.40 / halo 100) — now closes #166).
• Releases — v0.8.0 and v0.8.1 cut.

Recommendation

Update opportunistically — collective routing + VCS elab fixes look worth picking up. The new reduction hw feature is opt-in; HighTide's floonoc/asap7 variant should not be affected unless explicitly enabled. After the bump, re-baseline area/timing; check whether any of the bug fixes overlap the still-not-finishing floonoc/asap7 flow.
