+# Changelog
+
+All notable changes to this project are documented here. The format is based
+on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this project
+adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+## [2.0.0] - 2026-06-11
+
+### Added
+- Synthesize the morse ID from `--callsign` in memory (configurable `--wpm`
+  and `--tone`); no audio recordings required.
+- `--morse-file` to play a recorded WAV as the ID instead.
+- `--gap` and `--random-gap` for fixed or randomized quiet periods.
+- `--start`/`--stop` times for timed hunts.
+- `--cycles` to limit the number of transmit cycles (`0` = run until stopped).
+- Timestamped logging of every transmission.
+- GitHub Actions workflow that builds, smoke-tests, and releases `fox.jar`.
+- Contributor scaffolding: CONTRIBUTING, code of conduct, issue/PR templates.
+
+### Changed
+- Requires Java 26.
+- Default behavior is now run-until-stopped instead of a fixed 4000 cycles.
+
+### Fixed
+- Filename case mismatch that broke playback on case-sensitive filesystems.
+- Native audio line leak from opening a new clip per playback.
+- Inaccurate playback timing; playback now waits for the real end-of-clip event.
+- Errors are reported instead of silently swallowed.
+
+### Removed
+- Bundled `morse.wav` and `shh.wav`; the ID is synthesized and gaps are timed.
+

+# Contributing
+
+Thanks for your interest in improving the Fox Hunt Controller! Bug reports,
+feature ideas, and pull requests are all welcome.
+
+## Reporting bugs and requesting features
+
+Open an issue using the matching template. For bugs, include your OS, Java
+version (`java -version`), the exact command you ran, and what happened.
+
+## Development setup
+
+You need Java 26 or newer — nothing else.
+
+```sh
+git clone https://github.com/rbibby53/HAMRadioFoxHuntControllerJava.git
+cd HAMRadioFoxHuntControllerJava
+javac -d out/classes src/fox/*.java
+jar --create --file fox.jar --main-class fox.Fox -C out/classes .
+```
+
+## Testing your changes
+
+There's no test suite (yet — contributions welcome!), so test by running:
+
+```sh
+java -jar fox.jar --help
+java -jar fox.jar --callsign N0CALL --wpm 25 --repeats 1 --gap 1 --cycles 2
+```
+
+You should hear the callsign in morse twice, with a quiet gap between, and
+see a timestamped log line for each transmission. Please also exercise any
+option your change touches.
+
+## Pull requests
+
+- Branch from `master` and keep PRs focused on one change.
+- CI must pass — it compiles, packages, and smoke-tests the jar.
+- Match the existing code style: plain Java, 4-space indent, no external
+  dependencies. Part of this project's appeal is that it's a single small
+  jar with zero dependencies; please keep it that way.
+
+## Questions
+
+Open an issue — happy to discuss ideas before you write code.
