Summary
Adds
fern/docs/changelog/2026-09-30.mdx, covering September 2026. Drafted from the 404 PRs merged in the monorepo between 2026-09-01 and 2026-09-30.Headline items:
5042) is generally available across the Swap, Gasless, and Cross-Chain APIs — announcement, a New Chains entry, and a New Features entry covering its dual native/ERC-20 USDC interfaces./cross-chain/statuscorrectness./cross-chain/quotes, and RWA gating for the Reserve DTF tokens and PAXGy.Every endpoint, parameter, field, error code, and bridge provider ID named in the entry was checked against
fern/openapi.json,fern/openapi-cross-chain.json, or an existing docs page before being written. Liquidity-source names and their chains were resolved from the monorepo rather than inferred from PR titles, and each was confirmed to add a real sampler rather than only indexing coverage for something already routable. One source added and reverted inside the month is excluded; a same-named but distinct source that was not reverted is kept.Release Highlights
The homepage table now holds September and August only; the three July rows were removed. Column padding re-aligned, nothing else on the page touched.
5042) is now supported across all three APIsBoth September rows link to
#2026-09-30-…anchors. The Arc row points at the New Chains section rather than Announcements, matching how the July row avoided the emoji header.Stale docs fixed
None needed. September retired no chain, endpoint, or parameter, so nothing published went stale. The pages this sweep normally touches were checked and are already current:
introduction/supported-chains.mdx— Arc was added to the Swap/Gasless table, the Cross-Chain matrix, and kept in sync with its Gasless rollout by three separate human PRs during September. No edit needed.0x-swap-api/additional-topics/chain-specific-native-tokens.mdx— already documents Arc's USDC-as-gas model in full. The changelog links to it.introduction/faq.mdx,core-concepts/contracts.mdx, andcore-concepts/0x-cheat-sheet.mdx— all three agree with each other. See the note below.Overlap with open work: PR #283 edits
introduction/welcome.mdxandintroduction/faq.mdx. It does not touchindex.mdx, the changelog directory, orsupported-chains.mdx, so there is no conflict with this PR. I left both of its files alone.
