3.8.0

• bump botocore dependency specification to support
  "botocore >= 1.43.3, < 1.43.47" (#1605, #1606, #1635, #1651, #1655)
• port botocore 1.43.24's long-polling no-retry signal
  (handler_response is False) through the async retry path so retries
  don't block the event loop with a synchronous sleep during backoff (#1606)
• fix AIOHTTPSession/HttpxSession blocking the event loop on the
  first request per proxy: SSL context creation (certificate loading via
  load_verify_locations/load_cert_chain) now runs in a thread via
  asyncio.to_thread instead of directly on the loop (closes #1469)
  (#1587)
• restructure StreamingBody to subclass botocore.response.StreamingBody
  (dropping the wrapt.ObjectProxy wrapper) and add full httpx API
  parity — read(amt), readinto(), readlines(), async iteration,
  iter_lines()/iter_chunks(), tell(), close() — where
  read(amt) previously raised ValueError; note that
  AioStreamingBody.__aenter__ now returns self instead of the raw
  aiohttp ClientResponse (use .raw_stream for the underlying
  response) (closes #1365) (#1539)

3.7.0

• replace per-PR CHANGES.rst / __init__.py ceremony with an AI-drafted
  release flow: contributors no longer touch version or changelog files; a
  workflow-triggered agent synthesizes merged PRs into a release PR at release
  time (closes #1167) (#1592)
• add AioSession.warm_up_loader_caches() and warm_up_loader_caches
  option in AioConfig to pre-populate botocore loader caches off the event
  loop, avoiding blocking file I/O on first client/waiter/paginator use
  (closes #1199) (#1462)
• fix race condition in AioAssumeRoleProvider._visited_profiles causing
  false InfiniteLoopConfigError under concurrent async usage
  (closes #1455) (#1537)
• fall back to synchronous subprocess.run (via asyncio.to_thread) for
  credential_process when the running event loop does not implement
  subprocess transports — notably asyncio.SelectorEventLoop on Windows
  (closes #1415) (#1588)
