v0.7.0

Added

• Added read-only Elastic CLI context outputs through .es:/index and .context.es:/index, including context URL and credential resolution.
• Added .env fallback for missing ELASTIC_ES_URL and ELASTIC_ES_API_KEY settings used by env:/ outputs.
• Added the bundled _okf Elasticsearch template with Open Knowledge Format v0.2 mappings, shared index-pattern maintenance, and --template-name overrides.

Changed

• Raised the minimum supported Rust version from 1.88 to 1.89 for elasticrc compatibility.
• Replaced the elasticsearch:/index and es:/index environment targets with the explicit env:/index form.
