- Fixed changelog headers

## [1.0.0] - 2021-07-09

### Added

- `Mxpanel.Operation` struct. This struct holds all the information necessary
to one API operation. It can be delivered alone or grouped in batches.

### Changed

- All functions were updated to build a `Mxpanel.Operation` instead of
making a API request directly. The generated operation can be piped to
`Mxpanel.deliver/2` or `Mxpanel.deliver_later/2` to provide a single interface
for delivering information to Mixpanel API. This allow all operations to be batched.

- Buffers info telemetry event metadata changed to return the buffer sizes by supported endpoint.

in the `Mxpanel.track/4` function.
