Made the following changes:

• Updated Sphinx HTML theme and options
• Added initial release notes
• Added release notes to documentation

[greptile-apps]

Greptile Summary

The PR switches the documentation to NVIDIA's Sphinx theme and adds release-note navigation. It also introduces several documentation build blockers and a GitHub link targeting the wrong repository.

• Replaces the Read the Docs theme and custom CSS options with NVIDIA theme switcher and icon configuration.
• Adds release notes to the main documentation toctree.
• Adds an initial release-notes source file.

Confidence Score: 1/5

The PR is not safe to merge until the documentation theme dependency, missing source and metadata files, and incorrect repository link are corrected.

Current documentation builds cannot load the selected theme, resolve the release-notes toctree target, or copy the configured switcher assets, while the rendered GitHub navigation would direct readers to a different project.

Files Needing Attention: docs/conf.py, docs/index.rst, docs/release_notes

Important Files Changed

Filename	Overview
docs/conf.py	Changes the theme and navigation metadata, but the theme dependency and extra JSON assets are unavailable and the GitHub icon targets another project.
docs/index.rst	Adds a toctree target that cannot resolve because the corresponding file lacks the configured .rst suffix.
docs/release_notes	Adds an extensionless placeholder file that Sphinx will not recognize as the release_notes document.

Configured theme is unavailable

When CI, nightly publishing, or the documented local build runs, Sphinx loads nvidia_sphinx_theme, but those environments install or clone only sphinx_rtd_theme, causing the documentation build to abort before producing HTML.

[greptile-apps]

Toctree target cannot resolve

When Sphinx builds this toctree, it resolves release_notes using the configured .rst source suffix, but the PR creates only the extensionless docs/release_notes file, causing a nonexistent-document warning that the CI workflow's -W option turns into a build failure.

[greptile-apps]

Extra-path files are missing

When Sphinx processes html_extra_path, it attempts to copy project.json and versions1.json, but neither file exists and no build step generates them, causing missing-file warnings that fail the -W documentation build and leave the switcher data unavailable.

[mckimn]

This file should either be renamed to "release_notes.md" or the TE team will need to provide the release notes content as RST for future releases. They are currently provided as an MD file.

Suggested change

Suggested change

	release_notes
	release_notes.md

Only needed if content remains in MD.

[mckimn]

These will need to be created for the project.
