Jan 1, 2026January 2026 monthly summary for exasol/notebook-connector. Focus was on a security/configuration storage refactor within the Jupyter Notebook environment to replace the magic store mechanism with standard file access, enhancing reliability, clarity, and maintainability of configuration handling. This work reduces dependencies on IPython magic and standardizes file I/O across notebook contexts.

Aug 1, 2025In August 2025, delivered API consistency improvements for BucketFS in exasol/notebook-connector by renaming the open_bucketfs_connection API to open_bucketfs_bucket and adding a deprecation warning for the old name, guiding users to migrate. This reduces API ambiguity and paves the way for safer migrations across the repository.
