TRAC D.A.P. 0.5.8

TRAC D.A.P. 0.5.7

TRAC D.A.P. 0.5.7 is a feature release that adds support for streaming data operations in the web API. Both upload and download are supported. Since streaming upload is not (yet) supported in the grprc-web framework published by Google, this version of TRAC includes a new gRPC transport using WebSockets to support streaming operations. Client applications can enable the streaming transport by passing an option to the web API.

• Support for streaming upload and download operations in the web API
• Web sockets protocol support in the gateway, including authentication and connection management
• Intelligent management of user sessions with token auto-refresh and refresh limit
• Support for the PyPI "simple" protocol when loading model packages from PyPI
• Batching for related metadata updates (batches are atomic)
• Simplification of internal gPRC structures
• Various bug fixes and requested minor enhancements

Version 0.5.7 is metadata-compatible with versions 0.5.0 through 0.5.6.

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
