lwbgt 1.2.1

• Treat failure of a requested psychrometric solve as status -1 with NA numerical outputs. Skipping that solve can still yield successful WBGT results.
• Replace non-finite esat() results with NA and include them in the warning.
• Link other interfaces to the shared C kernel and expand input/output documentation.
• Synchronize with the shared patch release; native numerical results are unchanged.

lwbgt 1.2.0

• Add calculate(input, psychrometric = FALSE) to skip the independent psychrometric wet-bulb solve; its column is NA. The default remains TRUE.
• Synchronize private numerical helpers with the canonical C kernel.
• The internal native calculation routine now takes two arguments; existing calls to the exported R functions remain compatible.

lwbgt 1.1.0

• Synchronize with the shared release. The R API and reference-compatible native calculation are unchanged.
• Carry the expanded shared numerical corpus and cross-platform validation improvements documented in the project changelog.

lwbgt 1.0.1 (2026-10-01)

• Relax R test-suite golden-value comparisons to native single-precision tolerance for portability to R builds without long-double support.

lwbgt 1.0.0

• Stabilized the existing R interface and reference-compatible native v1 calculation. Numerical results and the default calculation are unchanged.
• Future numerical revisions will use explicit versioned interfaces.

lwbgt 0.4.3

• Synchronized the R package with project release 0.4.3. The direct C scalar API now writes estimated wind for 2 m input; the R output and WBGT results for valid inputs are unchanged.
• Expanded the retained-original comparison.

lwbgt 0.4.2

• Synchronized the R package version with project release 0.4.2; the R API and native numerical behavior are unchanged from 0.4.1.

lwbgt 0.4.1 (2026-09-29)

• Declared the CRAN-facing package license as Apache License 2.0.

lwbgt 0.4.0

• Added the first R interface with dependency-free vectorized lwbgt_input(), calculate(), and esat() functions.
• Added per-row validation, stable statuses, and R-native missing output handling.
• Bundled the reference-compatible native kernel directly into the package.
• Added direct GitHub installation and R-universe distribution.
