## [Unreleased]

## [v0.5.6] - 2023-03-24

### Added

- Add the following functions to the `Explorer.Series` module: `log/1`, `log/2`
and `exp/1`. They compute the logarithm and exponential of a series.

### Fixed

- Allow `Explorer.Series.select/3` to receive series of size 1 for both the
`on_true` and `on_false` arguments.

- Fix the encoding of special float values that may return from some series
functions. This is going to encode the atoms for NaN and infinity values.
