TRAC D.A.P. 0.5.6

With version 0.5.6 we are releasing pre-packaged SQL drivers for drivers that use permissive licensing, initially PostgreSQL and Microsoft SQL Server. This is intended to simplify the deployment process for those SQL dialects. We will explore publishing drivers for more dialects in this manner, depending on the licensing constraints of each driver.

Version 0.5.6 is metadata-compatible with versions 0.5.0 through 0.5.5.

TRAC D.A.P. 0.5.5

This version is a point release to expose additional configuration options, needed to use the S3 storage protocol on private hardware.

Version 0.5.5 is metadata-compatible with versions 0.5.0 through 0.5.4.

TRAC D.A.P. 0.5.4

This release is to document TRAC's capabilities for dealing with sensitive configuration during deployment.

• Updated the documentation site to include examples using secrets and other sensitive configuration elements
• The auth-tool utility has been renamed secret-tool and includes new tasks to help managing secrets
• TRAC D.A.P. 0.5.4 supports models using Python 3.11, which is now tested in CI

Version 0.5.4 is metadata-compatible with versions 0.5.0 through 0.5.3.

TRAC D.A.P. 0.5.3

TRAC D.A.P. 0.5.3 adds alternate mechanisms for supplying S3 credentials on AWS.

Version 0.5.3 is metadata-compatible with versions 0.5.0 through 0.5.2.

TRAC D.A.P. 0.5.2

TRAC D.A.P. 0.5.2 includes the base storage plugin for S3 storage on AWS.

Version 0.5.2 is metadata-compatible with versions 0.5.0 and 0.5.1.

TRAC D.A.P. 0.5.1

TRAC D.A.P. 0.5.1 is a patch release that adds a number of small fixes to 0.5.0. It also includes internal work needed to set up features scheduled for the 0.5.x release series.

Version 0.5.1 is metadata-compatible with version 0.5.0.

TRAC D.A.P. 0.5.0

TRAC D.A.P. 0.5.0 marks a new release series, adding significant features and updates to the previous 0.4.x series.

• New data pipeline framework to better integrate with Apache Arrow
• Authentication framework with two new authentication provider plugins
• Simplified metadata for FLOW objects with improved validation
• Two new platform APIs: listTenants() and platformInfo()
• Simplified configuration layout to allow generic handling of plugin configuration
• Support for in-place metadata upgrades across platform versions

TRAC 0.5.0 breaks metadata compatibility with the 0.4.x series. The metadata database can be upgraded in place using the deploy-metadb tool, however FLOW objects created in 0.4.x will not work with 0.5.0. All other metadata objects are unchanged and will work normally after an in-place upgrade.

TRAC D.A.P. 0.5.0 RC 4

RC 4 adds two major features to the 0.5 candidate series:

• Authentication framework, including local authentication provider plugins
• Flow simplification

TRAC D.A.P. RC 4 is not metadata compatible with RC 3 or any previous versions. Use the deploy-metadb tool to upgrade the metadata database.

TRAC D.A.P. 0.4.10

TRAC D.A.P. 0.4.10 is a maintenance release, to bring fixes from the upcoming 0.5 version to the 0.4.x series. The fixes included are:

• Improved error messages for model loading
• Fix a potential overflow in the local file writer
• Fix error handling for flows in the runtime, when there are errors in multiple models
• Fix data conformance logic when using inferred type hints from Pandas
• Fix UTF-8 encoding for metadata passing between the platform and the runtime
• Update GitHub workflows in light of recent GitHub deprecation warnings
• Update Python build dependencies to meet compliance rules

Version 0.4.10 is metadata-compatible with versions 0.4.0 through 0.4.9.

TRAC D.A.P. 0.5.0 RC 3

RC 3 adds a number of small fixes and performance improvements to the data pipeline.

TRAC D.A.P. 0.5.0 RC 3 is metadata compatible with RC 1 and 2 and the 0.4.x series. However there are likely to be metadata changes before the 0.5.0 release.
