TRAC D.A.P. 0.9.2

This is a security and patch release for the 0.9 release series.

Full Changelog: v0.9.1...v0.9.2

TRAC D.A.P. 0.10.0 Beta 1

This is a preview release including the new runtime extension mechanism, along with the first two extensions for OpenAI and HTTP connections. The new extension packages are available on PyPI here:

PyPI :: tracdap-ext-openai
PyPI :: tracdap-ext-http

Models and metadata are compatible between 0.9 and 0.10, however the extension API has been updated so 0.10 extensions depend on the 0.10 runtime.

TRAC D.A.P. 0.9.1

This is a security and patch release for the 0.9 release series. It also includes updates for storage authentication on Azure - managed identity authentication is now available for all three cloud storage mechanisms on their respective clouds.

TRAC D.A.P. 0.9.0

TRAC DAP 0.9 is a feature release of the TRAC platform, focused on cloud support and deployability. These changes are largely internal to the TRAC services and support cloud-native deployments on AWS, GCP and Azure. There are also significant changes to the configuration files.

TRAC 0.9 adds several new user-facing features, including:

• Support for categorical data types, including runtime support in Pandas and Polars
• Added a new structured object data type, using data classes or Pedantic models to define input and output datasets
• Runtime metadata support, allows models to query metadata attributes of their inputs to use in reporting
• Load resources from model code at runtime to generate outputs based on templates

A free-to-use version of TRAC is available on Docker Hub:

TRAC Desktop on Docker Hub

TRAC 0.8 models are fully compatible with TRAC 0.9, however there are significant changes in the configuration, storage and metadata layouts. TRAC 0.9 is not metadata compatible with 0.8.
