## New features

- RMST test is available (#188, thanks @LittleBeannie).
- Milestone test is available (#199, #204, #211, #237, thanks @LittleBeannie).
- Test version of `sim_gs_n()` is available with coming unit testing (#195, #201, #208, #212, thanks @LittleBeannie and @jdblischak).
- Users have the flexibility to create custom interim and final analyses cuttings according to their specific requirements by utilizing the `create_cutting_test()` function. (#215, #221, thanks @jdblischak).
- Users can create various testing approaches for interim and final analyses by utilizing the `create_test()` function. (#221, thanks @jdblischak).
- Users have the option to perform multiple tests on a simulated dataset using the `multitest()` function (#215, thanks @jdblischak).
- The output of tests (such as logrank test, weighted logrank test, RMST test, milestone test, MaxCombo tests) are unified as a list including method, parameter, estimation, se, z, p-value (#227, thanks @LittleBeannie).
- `rmst()` introduces the RMST test (#188, thanks, @LittleBeannie).
- `milestone()` introduces the milestone test
(#199, #204, #211, #237, thanks, @LittleBeannie).
- `sim_gs_n()` provides an experimental implementation for fixed sample size
group sequential design simulation, with unit tests upcoming
(#195, #201, #208, #212, thanks, @LittleBeannie and @jdblischak).
- `create_cut()` allows users to create custom interim and final
analyses cuttings based on their specific requirements
(#201, #221, thanks, @jdblischak).
- `create_test()` enables users to create various testing approaches for
interim and final analyses (#215, #221, thanks, @jdblischak).
- `multitest()` gives users the option to perform multiple tests on a
simulated dataset (#215, thanks, @jdblischak).
Note: This function is still experimental and may be improved in
future releases, as it was created prior to the standardization of
test functions in #227.
- Test outputs (logrank, weighted logrank, RMST, milestone, MaxCombo) are now
unified as a list including method, parameter, estimate, se, z-value, and
p-value (#227, thanks, @LittleBeannie).

## Bug fixes

- Correct the weights generated by `early_zero_weight()` under stratified designs (#233, thanks @LittleBeannie).

## Improvements

- Remove dependency of the bshazard R package (@234, thanks @nanxstats).
- Fixed incorrect weights generated by `early_zero()` under stratified designs
(#233, thanks, @LittleBeannie).

## Documentation

- Enriched documentation of `get_analysis_date()` (#186, thanks @LittleBeannie).
- Enhanced documentation for `get_analysis_date()` (#186, thanks, @LittleBeannie).

## Dependency

- Removed dependency on the bshazard package as it was archived by CRAN
(#234, thanks, @nanxstats).

# simtrial 0.3.2
