Track key changes for minor (second-digit) releases. Link each to ILAMB runs on the ILAMB landing page and note notable inputs/outputs.
6.0.x (2025-11)#
- Major methane and wetland dynamics: water table, oxygen pool, methane production/oxidation, ebullition, plant gas transport.
- New wetland-tolerant PFTs and parameters; configuration flag
with_methane; new inputs for slope, CH4, hydrotopes, optional ice/climate deltas. - Land-use restructuring and rice always irrigated; set-aside wetlands added.
5.10.x (2025-08 to 2025-10)#
- Added timing instrumentation flags (
-with_timing,-DUSE_TIMING) and maize/crop albedo fixes. - Parameter updates (alphaa, theta, CN ratios, turnover, nitrogen uptake) and acclimation of
bto temperature. - Options for deforestation burn handling (
luc_burn_startyear), nitrogen recovery cost flag, and phenology adjustments.
5.9.x (2025-03 to 2025-07)#
- Restart format with metadata; utilities for restart ↔ JSON/YAML and NetCDF input updates.
- NetCDF options for routing/reservoir/irrigation inputs; numerous utility improvements and leak fixes.
- Added splitclm/regrid helpers, pedantic env flags, and extensive bug fixes in I/O and scaling.
5.8.x (2023-11 to 2023-12)#
- New cultivation types and agricultural tree/plantation PFTs; macros to toggle climate/land-use/mitigation input sets.
- Config files renamed to
.cjson, expanded climate (GSWP3-W5E5 default) and input mappings; nitrogen toggle macro. - Added tmin/tmax/humidity inputs; removed GLDAS default.
5.7.x (2023-08 to 2023-11)#
- Land fraction/lake routing enhancements, new lake/land area outputs, and landfrac file support.
- Wood density now PFT-specific; added irrigation/river storage outputs and routing fixes.
- Numerous bug fixes in turnover, phenology, and set-aside handling.
5.6.x (2023-04 to 2023-08)#
- Changelog introduced; coupling start-year flag and NetCDF input options.
- New outputs for nitrogen fluxes and biomass grass harvest modes; config flags renamed/cleaned.
- Fixes across soil parameters, restart handling, and I/O stability.
Adding a new version entry#
- Add a section labeled
<major>.<minor>.x (YYYY-MM)with 3–4 bullets on scope, key flags/inputs, and major fixes. - Link its ILAMB run from the landing page and note any required inputs or configuration flags.
