+## [1.2.0] - 2023-02-13
+
+### Deprecation Warning
+
+- This release marks the end of support for Python 3.8.x.
+- Although version 1.0.0 was intended to support Python 3.8.x, PyCharm failed to warn about a specific type annotation
+  incompatibility. As a result, I was not aware that the support was not properly implemented.
+- This release adds full support for Python 3.8.x, but it will be the only release with such support.
+
+### Added
+
+- The `dl` command CLI now includes Bitrate Selection options: `-vb/--vbitrate` and `-ab/--abitrate`.
+- The `dl` command CLI now includes an Audio Channels Selection option: `-c/--channels`.
+- If a download worker fails abruptly, a full traceback will now be printed.
+- The aria2c downloader has a new parameter for downloading a specific byte range.
+
+### Changed
+
+- The usage of `Path.with_stem` with `Path.with_suffix` has been simplified to `Path.with_name`.
+- When printing audio track information, the assumption that the audio is `2.0ch` has been removed.
+- If audio channels were previously set as an integer value, they are no longer transformed as e.g., `6ch` and now
+  follow the normal behavior of being defined as a float value, e.g., `6.0`.
+- Audio channels are now explicitly parsed as float values, therefore parsing of values such as `16/JOC` (HLS) is no
+  longer supported. The HLS manifest parser now assumes the track to be `5.1ch` if the channels value is set to
+  `.../JOC`.
+
+### Fixed
+
+- Support for Python `>=3.8.6,<3.9.0` has been fixed.
+- The final fallback FPS value is now only obtained from the SegmentBase's timescale value if it exists.
+- The FutureWarning that occurred when getting Segment URLs from SegmentTemplate DASH manifests has been removed.
+- The HLS manifest parser now correctly sets the audio track's `joc` parameter.
+- Some Segmented WEBVTT streams may have included the WEBVTT header data when converting to SubRip SRT. This issue has
+  been fixed by separating the header from any previous caption before conversion.
+- The DASH manifest parser now uses the final redirected URL as the manifest URI (#25).
+- File move operations from or to different drives (e.g., importing a cookie from another drive in `auth add`) (#27).
