In `@en/docs/ai-gateway/next/about-this-release.md`:
- Line 1: Use sentence case for the headings in both release pages: in
en/docs/ai-gateway/next/about-this-release.md, change “AI Gateway Changelog” to
“AI Gateway changelog” and “Config Changes” to “Config changes”; make the same
heading changes in en/docs/api-gateway/next/about-this-release.md, changing “API
Gateway Changelog” to “API Gateway changelog”.
- Line 1: Both release pages, en/docs/ai-gateway/next/about-this-release.md:1-1
and en/docs/api-gateway/next/about-this-release.md:1-1, need frontmatter
inserted before the H1. Add title, description, canonical_url, md_url, tags,
author or authors, last_updated, and content_type to each page, preserving the
existing release heading and content.
- Line 6: Fix the heading hierarchy in both
en/docs/ai-gateway/next/about-this-release.md:6-6 and
en/docs/api-gateway/next/about-this-release.md:6-6 by changing main section
headings such as “New feature additions” to H2 and keeping “New policies” as H3
beneath them.
- Line 20: Remove the unmatched trailing colon after the AWS authentication link
in both en/docs/ai-gateway/next/about-this-release.md (lines 20-20) and
en/docs/api-gateway/next/about-this-release.md (lines 20-20); no description is
being added.
- Line 10: Update both en/docs/ai-gateway/next/about-this-release.md:10-10 and
en/docs/api-gateway/next/about-this-release.md:10-10 to define or glossary-link
MSSQL, AWS, MCP, LLM, IDP, REST, gRPC, APIP_*, and xDS at first use, linking
WSO2-specific terms to the root glossary.
- Line 12: Resolve the contradictory upstreamDefinitions documentation by
verifying the runtime behavior, then update the release-note entry in both
en/docs/ai-gateway/next/about-this-release.md and
en/docs/api-gateway/next/about-this-release.md at line 12 to consistently state
whether query strings and path fragments are supported or rejected.
