kache 0.2.0: zero-copy, content-addressed Rust build cache (RUSTC_WRAPPER)

kache 0.2.0

The first release we're comfortable promoting widely. Local content-addressed caching with hardlink-based restoration is stable; direct kache sync to S3-compatible backends has been in production for months. The remote prefetch planner is still SOON.

What's Changed

• docs(readme): add demo + monitor GIFs, reframe WIP server as SOON by @jleni in #38
• docs: pre-launch onboarding pack (CI, contributing, templates) by @jleni in #39
• chore: pre-0.2.0 polish — Cargo.toml metadata + tighter README description by @jleni in #41

Full Changelog: v0.1.1...v0.2.0

v0.1.1

What's Changed

• Improve TUI loading state and docs screenshots by @jleni in #35
• feat: improve prefetch telemetry by @jleni in #36

Full Changelog: v0.1.0...v0.1.1

v0.1.0

What's Changed

• perf(remote): tune S3 HTTP pool idle timeout to 300s by @jleni in #31
• add kunobi auth and ha support by @jleni in #33
• docs: clarify local cache and remote server status by @jleni in #34

kache v0.0.35: safer setup and daemon restarts for Rust build caching

kache is a zero-copy, content-addressed Rust build cache. It runs as a RUSTC_WRAPPER, restores local cache hits through hardlinks, and can share artifacts through S3-compatible storage for CI and multi-machine development.

This release focuses on making first-run setup and daemon recovery less surprising:

• kache init can configure Cargo, install the background daemon as a login service, and start it in one pass. Before editing ~/.cargo/config.toml, it now creates a backup so setup can be retried or rolled back safely.
• kache daemon restart now verifies daemon health instead of treating a stale socket as success. kache init also surfaces daemon startup failures instead of reporting a healthy setup too early.
• kache doctor and restart handling recover stale daemon state more reliably and detect legacy cache-wrapper leftovers that can interfere with builds.
• The optional remote planner service now uses SurrealKV-backed embedded storage, reducing operational dependencies for preview and small service deployments.
• The project now pins Rust 1.95 via rust-toolchain.toml and updates key dependencies, including reqwest and rusqlite.

Install and try it:

cargo binstall kache
kache init
kache doctor

For source builds:

cargo install --git https://github.com/kunobi-ninja/kache
