 # Changelog
 
+## v1.3.2
+
+### Bug fixes
+
+- **Cursor blink fix** -- the event loop was redrawing every 50ms regardless of
+  state changes, resetting the terminal's cursor blink timer. Now frames are only
+  drawn when state actually changes (#177)
+
+### Enhancements
+
+- **Proxy config** -- added a `proxy` field to `config.toml` for Signal TLS
+  proxy URLs, passed through to signal-cli as `--proxy`. Useful for connecting
+  in censored regions (#178)
+
+### Developer
+
+- **Fuzz testing** -- added `cargo-fuzz` harnesses for JSON-RPC parsing, UTF-8
+  cursor operations, keybinding parsing, and slash command parsing (#179)
+
+---
+
+## v1.3.1
+
+### Bug fixes
+
+- **Image attachments** -- fixed image attachments not rendering after restart on
+  Unix (#175)
+- **Quit aliases** -- added `:q` and `:quit` as aliases for `/quit` (#174)

+## Fuzz testing
+
+The `fuzz/` directory contains [cargo-fuzz](https://rust-fuzz.github.io/book/cargo-fuzz.html) harnesses for external input boundaries. Fuzz testing requires **nightly Rust** and **Linux or macOS** (libfuzzer does not support Windows).
+
+```sh
+cargo install cargo-fuzz
+cargo +nightly fuzz run <target>
+```
+
+### Fuzz targets
+
+| Target | What it tests |
+|---|---|
+| `fuzz_json_rpc` | JSON-RPC deserialization and `parse_signal_event` / `parse_rpc_result` |
+| `fuzz_input_edit` | UTF-8 cursor navigation and string mutation at byte boundaries |
+| `fuzz_key_combo` | `parse_key_combo` with arbitrary strings from user TOML files |
+| `fuzz_command_parse` | `parse_input` with arbitrary slash commands |
+
+Run `cargo fuzz list` to see all available targets. Any panic found by the fuzzer is a bug to fix.
