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 b to 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.
