Wisp v0.2.0rc3

RC3 makes Rust the sole interactive terminal interface. The published native wheels support macOS arm64 and Linux x86_64 with glibc 2.28 or newer. Other platforms receive a pure wheel with print, JSON, RPC, and SDK support; it does not provide an interactive TUI. Python 3.12+ is required. The stable installation pin remains 0.1.0.

Try this prerelease without replacing an existing installation:

uvx --from "wisp-ai==0.2.0rc3" wisp --version
uvx --from "wisp-ai==0.2.0rc3" wisp

See the 0.2 upgrade guide for behavior changes and rollback. The public verification report records published artifact hashes, provenance, and installed-package smoke results. Real-provider and native-terminal dogfooding remain part of the prerelease trial.

Wisp v0.2.0rc2

Known Intel Mac installation limitation: Fresh Cargo-free PyPI installation fails on macOS x86_64. RC2 requires cryptography>=50.0.0; upstream stopped publishing Intel macOS wheels in version 49. The Intel Wisp wheel exists, but a fresh dependency installation requires source-building tooling. Apple Silicon and Linux public installs passed. See the failed Intel check and upstream changelog. This remains an unresolved release-acceptance gap; no three-platform success is claimed.

Wisp 0.2.0rc2 trials the Rust TUI as the default on native macOS arm64/x86_64 and Linux glibc 2.28+ x86_64 installations. The Python runtime continues to own providers, tools, permissions, and sessions. Textual remains installed and maintained; select it explicitly with wisp tui --renderer textual. Pure/source installations without a native binary retain Textual.

This candidate includes semantic terminal colors and complete saved-transcript loading without a history cap. Known Rust UI differences include transcript search/copy/drag selection, clickable Markdown links, and integrated updates.

Install the candidate explicitly:

uv tool install --force "wisp-ai==0.2.0rc2"
wisp --version
wisp

Stable remains 0.1.0. See the upgrade guide for Python API and live-RPC compatibility changes; its prepublication status paragraph reflects when the tagged source was prepared.

Public installation verification

Release workflow passed. Exactly five PyPI distributions match the corresponding GitHub release bytes. All 15 original build assets passed GitHub attestation verification against the release workflow, tag, and commit af13bf11fce1575ca760a87a3a552b41165141b7.

Fresh public-install matrix:

Platform	Public install and lifecycle	10,001-message ready frame
macOS arm64	Passed	3.877 s
Linux glibc 2.28 x86_64	Passed	3.782 s
macOS x86_64	Failed: dependency wheels unavailable	Not run

Passing targets verified exact native wheel selection, installed SDK imports, Rust default prompt/exit, explicit Textual prompt/exit, full-history resume, native/pure replacement, corrupted-binary failure, restoration, offline reinstall, uninstall, and terminal restoration. Intentional corruption tests use uv copy mode to avoid changing the shared installer cache. Measurements are individual synthetic fake-provider observations, not cross-platform benchmarks or cross-version downgrade evidence.

Full Changelog: v0.2.0rc1...v0.2.0rc2

Wisp v0.2.0rc1

Wisp 0.2.0rc1

An opt-in release candidate for the 0.2 line. 0.1.0 remains the recommended stable release.

Highlights

• Textual remains the default TUI, with improved streamed-output ordering, input responsiveness, and file-picker behavior.
• Hardened harness lifecycle and message ownership, plus deterministic interruption/recovery coverage for streaming, tools, queues, and context transitions.
• Backend-owned provider connection and model-catalog RPC, with live RPC v4 and event schema v36.
• The Rust TUI remains experimental and source-build opt-in; Python distributions do not bundle a Rust binary.

Try the candidate

uvx --from "wisp-ai==0.2.0rc1" wisp --version
uvx --from "wisp-ai==0.2.0rc1" wisp

These commands do not replace an existing persistent installation, but Wisp still uses normal configuration and session locations. Use a disposable project and back up important sessions when testing.

Integration changes: the deprecated wisp.agent.messages.SessionEntry(...) factory and old agent-internal import paths were removed. External JSONL-RPC clients must negotiate live RPC v4. Supported historical session files remain readable. Read the 0.2 upgrade guide before updating integrations.

Verification and feedback

Merged-commit CI, the release dry run, and the publishing workflow passed on d41c8a4. Published-package checks verified the CLI version, installed SDK imports, and a fake-provider prompt outside the source checkout. Wheel and source-distribution hashes agree between PyPI and GitHub.

Before final 0.2.0 promotion, please dogfood real-terminal streaming while typing and scrolling, cancellation, approvals, file navigation, and session resume. Report regressions with your OS, terminal, and a minimal reproduction; headless tests do not establish native-terminal visual correctness.
