 Releases are built and published automatically by the [Release](.github/workflows/release.yml) GitHub workflow
 whenever a version tag is pushed to the repository.
 
-The version is taken from the tag, so there is no version number to update in the code. Create and push a tag
-with a leading `v`, following the naming convention described in `gradle.properties` (e.g. `v0.6.2-alpha-1`,
-`v0.6.2-beta-1` or `v0.6.2`):
+1. Update `projectVersion` in `gradle.properties` to the new version, following the naming convention described in
+that file (e.g. `0.6.2-alpha-1`, `0.6.2-beta-1` or `0.6.2`).
+2. Commit and push the change to `master`.
+3. Create and push a tag that matches the version with a leading `v`:
 ```
 git tag v0.6.2-beta-1
 git push origin v0.6.2-beta-1
 ```
 
-Builds made from an untagged commit get a version like `0.6.2-beta-1-14-g4626d567` (14 commits after the
-`v0.6.2-beta-1` tag, at commit `4626d567`), with `-dirty` appended when there are uncommitted changes.
-
 The workflow then:
-* Verifies that the version the build derives from git matches the tag and fails if it does not.
+* Verifies that the tag matches `projectVersion` in `gradle.properties` and fails if it does not.
 * Builds and tests the code, then creates the release zips for Linux, Mac and Windows (x86-64 and aarch64).
 * Creates a GitHub release titled `Version <version>` with auto-generated release notes (a "What's Changed" list of
 the PRs merged since the previous version tag), and attaches the six zip

-/**
- * Playlist channel layer.  Draws each playlist channel, enabled (processing) or disabled, and each active traffic
- * channel (tracked from the channel processing start and stop events) as a translucent box at its frequency and bandwidth, labeled with the system, site, channel name and
- * decoder.  Processing and selected channels use their own colors.  When the decoder applies a frequency correction,
- * a bracket at the bottom of the box shows the corrected channel position and the PPM error.
- *
- * When the zoom level is too low for a channel's labels to fit in its box, moving the mouse over the channel shows a
- * popout card near the bottom of the spectrum (or the waterfall) with the channel name, system, site, decoder,
- * frequency and state.  The popout can be turned off with the hover details setting.
- *
- * Right-clicking a channel adds a menu item to view or edit the channel in the playlist editor.
