* chore: Update changes-filter.yaml to include docker paths Added docker-related paths to the changes filter configuration, ensuring that changes in the docker directory, uv.lock, pyproject.toml, and backend source files are tracked appropriately. * chore: Update docker_test workflow trigger to use workflow_call Modified the GitHub Actions workflow for testing Docker images to trigger on workflow_call instead of push events, streamlining the CI process for Docker-related changes. * chore: Enhance CI workflow to include Docker testing Added a new job for testing Docker images in the CI workflow, ensuring that Docker-related changes are validated. Updated conditions to include Docker outputs in the path filter and CI success summary. * chore: Update changes-filter.yaml to include frontend paths Added frontend source paths and .dockerignore to the changes filter configuration, ensuring that changes in the frontend directory are tracked alongside existing Docker-related paths.
Caution
- Langflow versions 1.6.0 through 1.6.3 have a critical bug where
.envfiles are not read, potentially causing security vulnerabilities. DO NOT upgrade to these versions if you use.envfiles for configuration. Instead, upgrade to 1.6.4, which includes a fix for this bug.- Windows users of Langflow Desktop should not use the in-app update feature to upgrade to Langflow version 1.6.0. For upgrade instructions, see Windows Desktop update issue.
- Users must update to Langflow >= 1.3 to protect against CVE-2025-3248
- Users must update to Langflow >= 1.5.1 to protect against CVE-2025-57760
