HA 2026.6 Compatibility, Tab Reordering, Sidebar Startup Option & ZIP Transfer Improvements
Blueprint Studio 2.5.3
This release focuses on Home Assistant 2026.6 compatibility, smoother editor workflows, safer ZIP handling, and much better large-file transfer behavior.
Highlights
- Editor tabs can now be reordered by dragging, with tab order preserved across reloads.
- Home Assistant 2026.6 compatibility updates, including removal of legacy
platform: templatesensor autocomplete. - Python script payload validation fixed so
entity_idinsidedata:is no longer incorrectly warned as deprecated forpython_script.*services. - Sidebar startup behavior is configurable with a new Auto-Hide Sidebar on Startup setting.
- Large ZIP downloads now stream in chunks for local and SFTP folders, reducing memory usage and avoiding browser hangs.
- ZIP download progress overlay now shows processed files, transferred bytes, and the current archived file.
- ZIP uploads are safer with traversal, absolute path, Windows drive path, and NUL-name protection.
- Folder ZIP uploads now use multipart transfers, avoiding Home Assistant JSON body limits.
- Upload progress is non-blocking, allowing users to keep working while large uploads continue.
- SFTP media previews now stream directly with HTTP Range support, improving seeking and reducing browser memory usage.
- Error toasts and modal error flows are now dismissible.
Fixes
- Fixed Jinja syntax highlighting inside YAML folded/literal block scalars after whitespace-only lines.
- Fixed ZIP extraction reporting failure after partial success when only some archive members fail.
- Fixed local ZIP folder uploads not refreshing the explorer immediately after extraction.
- Fixed selected-item ZIP downloads by using short-lived authenticated stream URLs instead of buffering full archives in the browser.
