v0.6.0

COSMICA v0.6.0 is a breaking cleanup and maintenance release. It removes legacy APIs that had been deprecated in previous releases, drops Python 3.12 support, and continues the migration toward the newer typed model layer. It also adds gateway-network helpers and includes several CI, packaging, and security hardening updates.

Breaking Changes

Remove the experimental packet-routing module

The experimental_packet_routing module has been removed. This module was experimental and is no longer part of the public package surface.

by @shunichironomura in #113

Remove deprecated classes, functions, and TOML loaders

Deprecated compatibility APIs have been removed across cosmica.dynamics, cosmica.models, cosmica.topology, and cosmica.visualization.

Notable removals include the old orbit and constellation classes/functions from cosmica.dynamics, TOML-based object loading helpers, and old topology-builder support for the previous constellation model. Users should migrate to the newer model-layer APIs such as cosmica.models.SatelliteOrbitModel, cosmica.models.CircularSatelliteOrbitModel, cosmica.models.EllipticalSatelliteOrbitModel, cosmica.models.Constellation, and cosmica.models.build_walker_delta_constellation.

Drop Python 3.12 support

COSMICA now requires Python 3.13 or newer.

by @shunichironomura in #122

Add optional generic type parameters to satellite and constellation classes

Satellite and constellation classes now accept optional generic type parameters for their identifier types. This improves static typing of constellation models, but may require updates in downstream code that uses explicit type annotations.

Features and Improvements

Add gateway network building methods

A new gateway-network helper was added for constructing a default gateway network, making it easier to set up scenarios that include gateway nodes.

Better cooldown handling

Add cooldown settings to Renovate config to be robust against supply chain security risks.

Fixes

• Fix the return type hint of preserve_tick_params in visualization utilities. (by @shunichironomura in #123)

Packaging, CI, and Security

• Remove deprecated license classifiers and rely on modern license metadata. (by @shunichironomura in #119)
• Pin GitHub Actions versions by commit SHA for supply-chain hardening. (by @shunichironomura in #134)
• Adopt Renovate best-practice configuration and add exclude-newer configuration for uv. (by @shunichironomura in #135, #137)
