- Added variable panels through the `--panels` and `--terminal-width` flags, see [#13](https://github.com/sharkdp/hexyl/issues/13) and [#164](https://github.com/sharkdp/hexyl/pull/164) (@sharifhsn)
- Added new `--group-bytes`/`-g` option, see #104 and #170 (@RinHizakura)
- Added new `--base B` option (where `B` can be `binary`, `octal`, `decimal` or `hexadecimal`), see #147 and #178 (@sharifhsn)
## Bugfixes
## Other
- More tests for the squeezing feature, see #177 (@mkatychev)
- Show actual zero bytes as `⋄` in the character panel (previously: `0`), in order not to confuse them with ASCII
`0` bytes if colors are deactivated. Closes #166 (@sharkdp)
## `hexyl` as a library
- Breaking change: `Printer::new` is deprecated as a part of the public API. Alternatively, you can now construct a `Printer` using the `PrinterBuilder` builder API, see [#168](https://github.com/sharkdp/hexyl/pull/168). (@sharifhsn)
## Other
- More tests for the squeezing feature, see #177 (@mkatychev)
## Thank you
