0.85.0

The 0.85.0 release delivers powerful pipeline execution enhancements and caching improvements that provide users with greater control over pipeline behavior.

⚠️ Breaking Changes

• Local Orchestrator Behavior: The local orchestrator will now continue executing steps after some steps fail (instead of stopping execution immediately)
• Docker Package Installer: Default Python package installer in Docker settings switched from pip to uv
• Log Endpoint Format: Log endpoints return a different format - affects manual API access but not regular pipeline operations
• Fetching Runs with old Client: Using a client of a previous release (<0.85.0) to fetch pipeline runs created by a client with version >=0.85.0 can cause an error if the run is in
  the new provisioning status.

📢 Upcoming Breaking Change

Important Notice for Future Release: In the next release, the base zenml package will no longer include dependencies for running ZenML connected to a local database.. Users will only be able to connect to deployed ZenML servers with the base package.
To continue using ZenML locally with a SQLite database, install with the local extra: pip install 'zenml[local]'. If you're using ZenML with a local server, you're already installing zenml[server] and this change will not affect you.

🚀 New Features

Pipeline Execution Modes

• Flexible Failure Handling: Configure what happens to a pipeline run when any step fails, providing fine-grained control over pipeline execution behavior

Advanced Caching System

• Value-Based Caching: Materializers now support caching artifacts based on their actual content/value rather than just artifact ID, enabling more intelligent cache reuse
• Cache Policies: New cache policy system allows users to specify precisely when a step should be cached, providing granular control over caching behavior

Airflow 3.0 support

• Airflow 3.0 Compatibility: Support for Apache Airflow 3.0, ensuring compatibility with the latest Airflow features and improvements
