27.0.0

What's Changed

Protocol 27 Support

• Updated protocol dependencies and the Soroban SDK to Protocol 27, and added support for signing the new AddressV2 auth entries (#2613).

New Features

• Added --auth-mode (and STELLAR_AUTH_MODE) to contract invoke/deploy/upload and tx simulate, with enforce, root, and non-root modes — enabling non-root authorization, which the CLI could not produce before (#2602).
• Added --only-commit to stellar version to print just the build commit sha (#2592).

Security

• stellar env now conceals secret-bearing values by default, requiring --reveal to print them — fixing an inverted check that leaked credentials in plain text (#2597).
• stellar snapshot create now redacts credentials in the archive URL printed to stderr (#2598).

Docker & Packaging

• Installed missing runtime libraries so the Docker image starts correctly (#2594).
• Built images from source on native per-architecture runners (#2605, #2606) and tagged :latest only for the newest release (#2607).
• Added retries to the install action (#2608) and fixed tar usage on Windows (#2612).
