v1.0.0

IMPSY v1.0.0

First stable release. Marks the new web UI as the primary user-facing surface and stabilises the runtime configuration.

Web UI

• Redesigned on Bootstrap 5 with Dashboard, Logs, Datasets, Models, Config, Commands, and Realtime pages (#69)
• Setup wizard with onboarding flow and file management (#67, #31)
• Realtime page showing live input/output vectors via a dedicated localhost OSC monitor channel
• Commands page for live mode switching, pause, reset, and sigmatemp/pitemp/timescale tuning (#34)
• Dedicated localhost OSC channel for webui ↔ run ([webui].monitor_port, [webui].command_port) so the webui works regardless of whether [osc] IO is configured

Live control

• New OSC addresses for live tuning: /impsy/sigmatemp, /impsy/pitemp, /impsy/timescale, plus mode/reset/pause (#72)

Configuration & documentation

• Full reference at docs/config.md covering every section (#30)
• New [webui] config section

Stability

• Bound MIDIServer.disconnect to avoid a python-rtmidi shutdown deadlock when Ctrl-C lands during active MIDI traffic
• Fixed webui OSC commands failing on macOS
• Fixed WebSocket channel handling
• Coerce wildcard osc.client_ip to localhost on the IMPSY side
• Guard compute_channel_labels against malformed mapping entries

Dependencies

• Pin keras-mdn-layer to PyPI v1.0.0 — installs no longer require git access
• Replaced pandas with numpy + csv stdlib (#29)
• Dependency bumps for dependabot alerts

Inherited from v0.7.0-alpha (since v0.6.0)

• Python 3.11 / 3.12 / 3.13 support
• TensorFlow 2.20.0 + ai-edge-litert
• TFLite model reconversion on load failure
• Removed TensorFlow Probability dependency (Keras 3 via keras-mdn-layer)
• CI matrix: 3 Python versions × 3 platforms

v0.7.0-alpha

IMPSY v0.7.0-alpha

Pre-release marking the current state before v1.0 development begins.

Changes since v0.6.0

• Python 3.11, 3.12, and 3.13 support — expanded from Python 3.12-only
• TensorFlow 2.20.0 + ai-edge-litert — switched to the new TFLite runtime
• Removed TensorFlow Probability dependency — switched to pure Keras 3 via keras-mdn-layer v0.7.0-alpha
• TFLite model reconversion on load failure — automatically reconverts old SELECT_TF_OPS .tflite models from sibling .keras or .h5 files
• CI full matrix — tests run across 3 Python versions (3.11, 3.12, 3.13) x 3 platforms (Ubuntu, macOS, Windows)
• Logger propagation fix — prevents logger output to stdout on Python 3.13

Closed Issues

• #41 — .keras model format (done)
• #47 — WebSocket IOServer (done)
• #37 — Duplicated MIDI output (done, multiple output ports supported)
