  Live probes of www.xilinx.com lifecycle/support paths and the GitHub Releases API for the
  Xilinx organization, 2026-09-04.
note: >-
  Xilinx has no API to version, deprecate or run an SLA against. Its lifecycle signal is
  software-release cadence in its own GitHub organization plus a hardware product-discontinuation
  programme that has migrated to AMD's documentation host.
versioning:
  scheme: per-repository semver, with named PYNQ releases (Belfast, Carlisle)
  api_versioning: n/a — no HTTP API exists, so there is no URL/header/media-type version scheme.
  cadence:
    - repository: XRT
      latest: 2.25.0
      released: '2026-08-18'
    - repository: brevitas
      latest: v0.13.2
      released: '2026-08-28'
    - repository: PYNQ
      latest: v3.1.2
      released: '2025-09-30'
  evidence: https://github.com/Xilinx/XRT/releases
deprecation:
  api_deprecation_policy: null
  api_deprecation_headers: null
  note: >-
    No RFC 8594 Sunset/Deprecation header policy, and no API deprecation policy, because there
    is no API. NO `Deprecation` pointer is emitted for this record — asserting one would credit
    Xilinx with an API deprecation policy it does not have.
  product_discontinuation_programme:
    exists: true
    kind: hardware/product PDN (Product Discontinuation Notice) and Customer Notices
    evidence:
      - url: https://www.xilinx.com/support/documentation-navigation/customer-notices.html
        status: 301
        redirects_to: >-
          https://docs.amd.com/search/all?value-filters=Document_Type_custom~%22Advisory+%26+Errata%7CCustomer+Notices+%26+Notes%22&content-lang=en-US
    note: >-
      The programme is real and long-standing, but the notices are now published on AMD's
      documentation host under AMD's document taxonomy — it is the parent company's surface,
      reached through a redirect from Xilinx's own domain.
status_page:
  exists: false
  url: null
  note: >-
    No status page found on any Xilinx-controlled host, and none is expected: there is no
    hosted service to report availability for. NO `StatusPage` pointer is emitted.
sla:
  published: false
  note: Support is contractual (AMD Adaptive Support), with no published availability SLA.

end_of_life:
  company_brand: >-
    Xilinx itself is end-of-life as an operating brand — AMD completed the $50B acquisition in
    February 2022 and every xilinx.com web path now 301s into amd.com. The GitHub organization
    github.com/Xilinx remains active and is the only surface still publishing under the name.
