## version 1.0.6
- `spiral_horizon()`: add a new argument `y_max`.
## version 1.0.5
- `spiral_initialize_by_time()`: add `normalize_year` argument which enforce every loop to represent a complete year.
- `spiral_initialize_by_time()`: radical lines are calculated in a way that they correspond to the proportion of month days in a year.
- `spiral_initialize()`: `polar_lines_by` now accepts a vector which defines where to draw polar lines.
- `spiral_initialize()`: add `clockwise` argument.
## version 1.0.4
- `spiral_initialize_by_time()`: `start` can only be set and `end` is automatically calculated based on `start` and `period`.
- fixed a bug of `s$draw_spiral()` where `curve()` method should be used insteaf of `spiral_length()`.
- `xscale` and `yscale` are now correctly calculated for the spiral viewport.
## version 1.0.3

- Add `period` argument in `spiral_initializer()`.
## version 1.0.2

- Add function `is_in_track()`.
- Argument `height` can be set as a unit object in `spiral_track()`.
- Fixed a bug when `reverse_y = FALSE` in `spiral_track()`.
- Add options `curved_inside` and `curved_outside` in `spiral_raster()`.
## version 1.0.1
