## [0.9.1] - 2021-07-??
### Added
- Support for `-` as input or output filename, indicating `stdin`/`stdout`.
- Ability to dump the PNG encoded version of output to `stdout`.
- Support for arbitrary scales with custom units.
- Support for linear scales (as opposed to the logarithmic dBFS scale supported in 0.9.0).

### Changed
- Main window is rendered on each iteration of the main loop. Underlying texture is still only updated when new windows are computed.

### Fixed
- \[SERIOUS\] Branch on uninitialized variable ([commit](https://github.com/rimio/specgram/commit/b13609afcdf66d781db70fb75f6869a052a49079)).
- Garbled window texture when no input is received.
- Tick labels no longer overlap; enforce minimum tick spacing based on text width.
