# kairos 2.3.0
## Bugfixes & changes
* Deprecate `simulate()`.

## Enhancements
* `bootstrap()` method for `MeanDate` objects gained new `interval`, `seed` and `rare` arguments.

## Breaking changes
* Fix `bootstrap()` method for `MeanDate` objects: revert the change introduced in v1.1.0. By default, bootstrap replicates are drawn from a multinomial distribution.

# kairos 2.2.1
## Internals
* List **aion** in `Depends`.
* Update package metadata.

# kairos 2.2.0
## New classes and methods
* Add `as_seriation()` to coerce objects to seriation orders.
* Add `assess()` to test the significance of seriation solutions (#4).
* Add `density_event()` and `density_accumulation()` to compute density estimates of event and accumulation dates.
* Add `order_rows()` and `order_columns()` to get permutation order.
* Add `refine()` to refine CA-based seriation.

## Enhancements
* Translate into French.

## Bugfixes & changes
* Fix a bug in `predict_event()` and `predict_accumulation()`: supplementary rows are no longer ignored.
* Fix calendar in `jackknife()` and `bootstrap()` methods for `EventDate-class`.
* Deprecate `get_order()` and `seriate_refine()`.

# kairos 2.1.1
## Internals
* Use latest dependencies.

# kairos 2.1.0
## New classes and methods
* Add `hist()` methods.

## Internals
* List **dimensio** in `Depends`.

# kairos 2.0.2
## Internals
* Follow changes in **dimensio** v0.5.0.

# kairos 2.0.1
## Bugfixes & changes
* Fix support for supplementary rows in `event()`.

# kairos 2.0.0
## New classes and methods
* Add `image()` methods.
* Add `coef()`, `fitted()`, `residuals()`, `sigma()` and `terms()` to extract values from `EventDate` objects.

## Internals
* `MeanDate`, `AoristicSum`, `RateOfChange` and `IncrementTest` classes now inherit from `TimeSeries` (see **aion**).
* Use **tinytest** instead of **testthat**.

## Bugfixes & changes
* Remove previously deprecated methods.

## Breaking changes
* Use **aion** for internal date representation.
* Use **graphics** instead of **ggplot2** to reduce hard dependencies (remove all `autoplot()` methods).
* For consistency, all `mcd()` methods now return a `MeanDate` object.

# kairos 1.2.0
## New classes and methods
* Add `seriate_refine()` method for `PermutationOrder` objects.

## Bugfixes & changes
* Deprecate `refine()`.
* `cutoff` argument of `event()` is defunct (use `rank` instead).

# kairos 1.1.0
## New classes and methods
* Add seriation methods: `seriate_rank()`, `seriate_average()`, `permute()`, `get_order()`.
* Add `SimulationMeanDate` to store mean date estimations from simulated assemblages.
* Add `simulate()` method for `MeanDate` objects.

## Breaking changes
* No longer use classes from **arkhe**.
* Fix `bootstrap()` method for `MeanDate` objects: resample with replacement instead of simulating observations from a multinomial distribution.

# kairos 1.0.1
## Bugfixes & changes
* Fix aoristic sum calculation (#1). `aoristic()` now calculates weights within the time blocks rather than at the break dates between blocks.

# kairos 1.0.0
* First release.
