Release notes

What is current, and what changed. The docs home page shows when this site was last published.

Current versions

Component Version
Python SDK (cloudsprite) 0.5.0 — private-beta wheel
Claude plugin (cloudsprite) 0.1.3
Hosted script runner scikit-rf 1.11.0

The SDK is a private beta installed from the wheel URL in your invite — see the Quickstart. A PyPI release is planned; when it lands, pip install cloudsprite replaces the wheel URL and these notes will say so.

Changes

2026-10-06

  • Python SDK 0.5.0. New cs.tdr_step() turns S-parameters into a time-domain reflection (TDR) trace that matches the Keysight PNA low-pass step: Kaiser window (kaiser_beta, default 6), 3-point DC fill and chirp-Z interpolation. Works on S11, or on SDD11 from a single-ended pair of a 2- or 4-port Touchstone file. TdrStep.to_traces() returns impedance and reflection-coefficient traces that you can store with one cs.publish call. Requires the [rf] extra.
  • The SDK reference now covers 0.5.0, including the RF analysis helpers (S-parameter metrics, cascade/de-embed, noise figure, link budget, matching and filter synthesis).
  • Hosted script runs use SDK 0.5.0, so cs.tdr_step is available in CloudScripts.

2026-08-27

  • Documentation site published at docs.cloudsprite.io: platform how-tos, the generated Python SDK reference, RF-domain notes, and scikit-rf guidance.
  • New Quickstart — install → API key → first upload → first query — and an SDK configuration reference.
  • Claude plugin 0.1.3: /plugin marketplace add cloudsprite-io/cloudsprite-plugin, OAuth sign-in with your CloudSprite account.
  • The HTTP API reference is temporarily unavailable while it is being revised; the Python SDK is the supported integration surface.

Earlier in the beta

  • Python SDK 0.1.2 private-beta wheel released to invitees, with the [rf] extra for Touchstone / scikit-rf support.
  • Hosted script runs pin scikit-rf 1.11.0 so laptop and runner numbers match.
