### Added - Add a function to calculate the psi matrix directly in log space ([#174](https://github.com/LAPKB/pharmsol/pull/174)) - optimize ODE ([#167](https://github.com/LAPKB/pharmsol/pull/167)) ### Fixed - address parser and simulator regressions ([#166](https://github.com/LAPKB/pharmsol/pull/166)) ### Other - Bump actions/checkout from 5 to 6 ([#169](https://github.com/LAPKB/pharmsol/pull/169))

### Added - Template path is now user defined ([#153](https://github.com/LAPKB/pharmsol/pull/153))

### Added - Implement into Data for Subject(s) ([#131](https://github.com/LAPKB/pharmsol/pull/131)) ### Other - moved the optim module into pharmsol, the idea is that the SppOptimizer and the EffectOptimizer both can be directly used in the model and because of this they belong in pharmsol - Bump actions/upload-pages-artifact from 3 to 4 ([#124](https://github.com/LAPKB/pharmsol/pull/124))

### Added - make mappings optional ### Fixed - Add missing implementation for occasion on Prediction ([#126](https://github.com/LAPKB/pharmsol/pull/126))

### Added - Adds the occasion index to events and predictions ([#123](https://github.com/LAPKB/pharmsol/pull/123))

### Added - Change how SDE predictions are calculated ([#115](https://github.com/LAPKB/pharmsol/pull/115)) - Update API for Data ([#102](https://github.com/LAPKB/pharmsol/pull/102)) - Support fixed and variable scalars for error models ([#106](https://github.com/LAPKB/pharmsol/pull/106)) ### Fixed - Fix test missing Some ([#114](https://github.com/LAPKB/pharmsol/pull/114)) - Handle NA in Pmetrics files ([#109](https://github.com/LAPKB/pharmsol/pull/109)) ### Other - Update diffsol to 0.6.5 ([#94](https://github.com/LAPKB/pharmsol/pull/94)) - Adding covariate benchmarks ([#107](https://github.com/LAPKB/pharmsol/pull/107)) - Update criterion and cached ([#105](https://github.com/LAPKB/pharmsol/pull/105))

### Other - quiet-lloq - Update CI for building and testing ([#97](https://github.com/LAPKB/pharmsol/pull/97))

### Other - cleaning up - renaming get_error_model to error_model - some documentation - error propagation - blq->lloq - blq->llq - support for BLQ
