Cloudflare is removing the CIDR-encoded Zero Trust route endpoints (POST/PATCH/DELETE .../teamnet/routes/network/{ip}) in favor of route_id-based endpoints, and removing the connections array from Cloudflare Tunnel list/get responses. Both retirements take effect October 5, 2026.

Cloudflare Workflows adds two billing dimensions: steps (Free: 3,000/day included; Paid: 500,000/month, then $0.80 per 100,000) and stored state (1 GB-month included, then $0.20 per additional GB-month). Billing starts no earlier than August 10, 2026; request and CPU-time billing are unchanged.

The deprecated Customer.lastIncompleteCheckout field and the entire Checkout type subtree (AppliedGiftCard, CheckoutLineItem, ShippingRate) are removed from the Customer Account API in version 2026-10, with no replacement field in that API. Shopify directs developers to Storefront API cart flows and Customer.orders instead.

Three changes: from July 15, 2026 FBM sellers in DE/FR/IT/ES face 90% on-time delivery requirements (listing deactivation from Sept 1) with handling time capped at 0-1 days; from July 27, 2026 the Product Type Definitions API splits non-media titles into item_name (75 chars) and title_differentiation (125 chars); External Fulfillment MFN shipments now initialize as ACCEPTED, with CREATED deprecated in late July 2026.

Starting with GraphQL Admin API version 2026-10, the priceRule field is removed from DraftOrderDiscountNotAppliedWarning, breaking apps that read it from draftOrderCalculate/Create/Update responses. Replace priceRule.title with discountTitle and priceRule.discountCodes.nodes.code with discountCode.

claude-opus-4-1-20250805 was deprecated June 5, 2026 and retires August 5, 2026 (replacement: claude-opus-4-8); claude-mythos-preview retired June 30, 2026 in favor of claude-mythos-5. Separately, temperature/top_p/top_k return a 400 error when set to non-default values on Opus 4.7+, Opus 4.8, and Sonnet 5.

Claude Fable 5 and Mythos 5 use the tokenizer introduced with Opus 4.7, which produces roughly 30% more tokens than earlier models for the same text, and billing reflects the higher counts. Token counts measured on older models must not be reused; the free count_tokens endpoint returns counts for the model you pass.

From July 7, 2026 all eligible VCS Lite sellers can enroll in Invoice by Amazon, so tools must skip invoice uploads when status is InvoiceCreatedByAmazon. From July 15, 2026 the Brazil Invoices API getInvoicesDocument ZIP includes cancellation XML files with a _CANCEL_NFE_XML suffix.

As of checkout UI extensions API version 2026-07, the useBuyerJourneyIntercept hook and block_progress capability are deprecated; existing extensions keep working on current versions but removal lands in a future release. Migrate business-rule enforcement to server-side cart and checkout validation Functions.

As of API version 2026-07, the discountedUnitPrice field on DraftOrderLineItem in the Customer Account API is deprecated. Use approximateDiscountedUnitPrice instead, which returns the discounted total divided by quantity as an approximate per-unit price.

Stripe API version 2026-06-24.dahlia adds description, footer, and custom_fields parameters to invoice_settings on subscription create/update, letting invoice content (PO numbers, contract references) be set at the subscription level instead of patching each generated invoice. Additive and non-breaking.

API version 2026-05-27.dahlia adds an optional discountable parameter for add-on invoice items on Subscriptions, Subscription Schedules, and Preview Invoice APIs. Items default to discountable: true, so coupons apply unless discountable: false is set explicitly.

API calls that trigger published ChatGPT workspace agents now authenticate with dedicated Workspace Agent access tokens sent as Bearer auth against api.chatgpt.com. Tokens are created in ChatGPT Admin with the Workspace Agents scope and are valid only for Workspace Agents operations.

OpenAI's Compliance API lets enterprise admins programmatically export audit records covering Codex activity (prompts, tool approvals, code review events) for eDiscovery, DLP, and SIEM pipelines. ChatGPT-authenticated Codex audit logs are retained up to 30 days on OpenAI's side.

New read-only Admin API endpoints (GET /v1/organizations/rate_limits and per-workspace variants) return configured limits per rate-limit group with values like requests_per_minute and input/output tokens per minute. Requires an Admin API key; limits can be read but not updated via the API.

Admin-key endpoints /v1/organizations/usage_report/messages and /v1/organizations/cost_report report token usage (1m/1h/1d buckets, groupable by api_key, workspace, model, service_tier, context_window, inference_geo) and daily USD costs. Data lands within about 5 minutes; not available on Claude Platform on AWS.

Browser Isolation now works with Gateway authorization proxy endpoints (previously only source-IP endpoints), enabling identity-based HTTP Isolate policies on PAC-file-proxied traffic without installing the Cloudflare One Client.

API version 2026-07 adds DraftOrderInput.deposit to the GraphQL Admin API for configuring partial upfront payments on draft orders, plus read-only deposit fields in the Customer Account API. Additive, Shopify Plus only; no migration required.

Amazon published the May 2026 SP-API Release Notes together with an updated SP-API Deprecation Schedule. The announcement itself lists no individual deadlines; the linked schedule is where per-API version retirement dates live.

The Listings Items API (v2021-08-01) now accepts new IVP audience values in purchasable_offer.audience (B2B_EDUCATION, B2B_HEALTHCARE, B2B_GOVERNMENT, B2B_INDUSTRIAL) alongside B2B and ALL, US marketplace only. Additive; sellers must be enrolled in Amazon Business Industry Vertical Pricing.
