Changes in version 0.3.0 - Improved lactate_threshold() performance by reducing repeated model preparation and minimizing expensive data wrangling in method pipelines. - Optimized plotting performance by removing ggplot_build() from x-axis adjustment and simplifying plot construction paths. - Added stronger input/model error handling for edge cases in fitting and segmentation routines. - Expanded test coverage with validation and golden-output regression tests for numerical stability. - Updated CI quality checks and coverage gates to better protect performance and correctness changes. Changes in version 0.2.0 (2023-11-16) - Added the function lactate_curve() to retrieve data for plotting the lactate curve and heart rate response. Changes in version 0.1.4 (2023-04-16) - Patched a modification to the Dmax method, which was producing negative values in a few edge cases. - Make sure that infinite values are not retrieved when converting intensity to log. Changes in version 0.1.3 - Patched a fix to the Dmax method that was producing very high estimations in a few cases. Changes in version 0.1.2 (2023-02-22) - Fixed missing log in intensity in the Log-log method. Changes in version 0.1.1 (2022-09-08) - Removed align attribute in img tag. Changes in version 0.1.0 (2021-12-03) - Added a NEWS.md file to track changes to the package.
