TRAC D.A.P. 0.5.13 adds a pure-python version of the Git model loader. This is for organisations or environments where the native Git loader cannot be used at runtime. In the future, the pure python loader may become the default. To use the new loader, set nativeGit: false as a property of the repository in trac-platform.yaml. This release also adds support for setting git config via the TRAC repository properties, this can be used to set any parameters in the git config file. This can be used to customise the SSL settings for the Git model loader in organisations with their own root CA to meet enterprise trust requirements.

• Add a pure-python implementation of the Git model loader
• Support for single-commit fetch
• Support for setting git config via the TRAC repo properties

TRAC D.A.P. 0.5.11 includes a lightweight web server as part of the platform distribution. This is in line with the principle of reducing technology dependencies and is particularly intended for larger organisations where requesting a web server from IT may not be a quick or simple process.

The TRAC web server offers these capabilities:

• Serve static content (GET, HEAD)
• Use any location supported by a TRAC storage plugin as the content root (e.g. cloud storage)
• Mime type mapping for common file types (using Apache mime.types configuration)
• URL re-writing

Version 0.5.11 is metadata-compatible with versions 0.5.0 through 0.5.10.
