Change Log
Canonical WEPP build/version history for wepp-forest.
Required maintenance rule:
- update this file whenever a new build or rebuild is made (including new release-tagged binaries and version-affecting commits).
- add new entries at the top (descending chronology).
- when a matching
release/wepp_<tag>_release_notes.mdfile exists, include a markdown link to it in that row'sNotescell; omit the link when no release notes file exists.
Reconstructed from git log using release/version-related commits (latest
first), through 07/19/2022.

(source only, no dated release binary cut) | Vendored winter.for day-end melt aggregation math defect fix (two-line correction at lines 441/458: signed-comparison fix pstvML + ngtvML .le. 0.0 and multiplier sign flip (1+ngtvML/pstvML)). Identified via Dun-dissertation crosswalk (docs/winter-codes-scientific-review.md §4.A); empirically latent (1166-hillslope WB-05B cohort scan shows class2=class3=0 across 21.7M winter-active rows — snowd does not produce negative hrmlt in current production data, so the patched branch is unreachable). 20-hillslope WB-05B parity validation: 20/20 bit-identical (no-op as expected). Fix is correct-when-it-fires, no-op otherwise. No dated release binary cut in this commit; vendoring to wepppy deferred until bundled with next release. Package: docs/ablation/20260516_winter_day_end_melt_aggregation_sign_defect/, status resolved-latent. |

wepp_260516fc1 |
Built release/wepp_260516fc1 + release/wepp_260516fc1_hill (and sidecars) with TARGET_TAG=260516fc1 HBP_SUPPORTED=true MODE2_MASTER_PASS_PROMPT_REQUIRED=false LINK_FLAGS='-mcmodel=medium -no-pie -lz' tools/build_wepp_dated_release.sh (first attempt without -lz failed zlib link symbols; recut with -lz). Release hashes: watershed e25b4ee5..., hillslope 706a12a2.... Validation: release host smoke (p962, p1) passed for both binaries, interpreter checks (/lib64/ld-linux-x86-64.so.2), hillslope watchlist (19/19), ablation artifact policy gate OK, full pytest -q (189 passed, 2 warnings), and reconciled-condenser watershed replay success marker (WEPP COMPLETED WATERSHED SIMULATION SUCCESSFULLY) with no parse/runtime signatures. |

wepp_260504 |
Built release/wepp_260504 + release/wepp_260504_hill using pinned /usr/bin/gfortran (TARGET_TAG=260504) with hash parity to src/wepp + src/wepp_hill (efb38304..., 5c705a37...). Validated release smoke for both binaries, hillslope watchlist (13/13), ELF interpreter compatibility (/lib64/ld-linux-x86-64.so.2), ablation artifact policy gate, and release fast-lane pytest (100 passed, 2 deselected) after marking tests/test_wb05f_h0001_process_guard_regression.py as long_running and replacing release-required targeted replay with WB-08A reduced-lane (H0001, H0461, H0022) coverage. |

gfortran |
wepp_260501 |
wepp_260501 / wepp_260501_hill was a release-candidate artifact cycle for the CONFLICT-001 U6C campaign, not a deployed production release. The prior promotion/deployment wording is superseded. The release/wepp_260501* artifacts, /workdir/wepppy/wepp_runner/bin/wepp_260501* vendored copies, and stakeholder brief were removed on 2026-05-03 after H2637 R2 re-examination showed only outlet recovery, not reproduction of the audit memo's worst-OFE symmetric metric. |

gfortran |
wepp_260430 |
Re-released wepp_260430/wepp_260430_hill to fix watershed master pass truncation introduced in the leap-year patch: src/wshpas.for leap-day assignment was in column 73 under fixed-form -ffixed-line-length-72, so ndays = 366 was truncated to ndays = 36, yielding truncated pass_pw0.txt and downstream EOF in wshred. Patched to fixed-form-safe multiline if ... then / ndays = 366 / endif, added regression test tests/test_wshpas_leap_day_guard.py, rebuilt binaries, and refreshed release artifacts with hashes b11c94d8... (wepp_260430) and 3b2fdd2b... (wepp_260430_hill). Validation: host smoke (wepp + wepp_hill), hillslope watchlist (12/12), ablation artifact policy gate, full pytest (80 passed, 2 warnings), reconciled-condenser manual watershed replay success marker with no parse/runtime signatures, interpreter checks (/lib64/ld-linux-x86-64.so.2), and targeted reproduction closure (pass_pw0.txt full 18262 tokens ending SUBEVENT 50 365). |
| 04/30/2026 | 6084c260 (dirty tree leap contract patch) |
gfortran |
wepp_260430 |
Updated leap handling in src/stmget.for, src/contin.for, src/wshdrv.for, and src/wshpas.for to use Gregorian classification (/4 except /100 unless /400) while retaining a non-400 centurial day-366 tolerance path in runtime day-count loops. Rebuilt/published release/wepp_260430 + release/wepp_260430_hill (hashes ecee0f1a... and 5b1d758e...). Validated source-binary smoke on both binaries, hillslope watchlist (12/12), ablation artifact policy gate, full pytest -q (79 passed, 2 warnings), reconciled-condenser watershed replay success marker with no parse/runtime signatures, ELF interpreter compatibility (/lib64/ld-linux-x86-64.so.2), and centurial controls (year100/365 no false warning, year100/366 tolerated success, year2000/366 leap success). |

gfortran |
wepp_260429 |
Hotfix rebuild to remove accidental always-on observability overhead in src/wepp_observe.for: restored strict wepp_observe.on opt-in for all tags and cached the observe-flag inquire(...) result once per process to eliminate per-call filesystem probes in hot paths. Rebuilt/overwrote release/wepp_260429 + release/wepp_260429_hill; hashes moved from 35b2aabd.../f8977a96... to 225f1759.../0a7a5ced.... Validated host smoke on both binaries, ablation artifact policy gate, full pytest (79 passed, 2 warnings), and high-concurrency /wc1 hillslope timeout repro closure (fails=32 -> fails=0). |
