Features Added

• Added support for parsing space character in place of 'T' in RFC3339 DateTimes.
• Added support for HTTP proxy servers, both unauthenticated and with basic authentication.
• Added universal support for several TLS options:
  • Added the ability to set the expected TLS root certificate for TLS connection (useful if a proxy server uses a TLS certificate that is not chained to a known root).
  • Added the ability to enable TLS certificate revocation list checks (off by default).
    • For libcurl only: Allow TLS connection to succeed if CRL retrieval fails.
    • NOTE: This change only applies if libcurl is built using the OpenSSL crypto backend. It does NOT apply if libcurl uses the schannel (Windows default) or SecureTransport (macOS/iOS default).

Breaking Changes

• Changed the name of several distributed tracing HTTP span attributes:

  • requestId is renamed to az.client_request_id
  • serviceRequestId is renamed to az.service_request_id

• Bearer token authentication will not work for endpoint URL protocol schemes other than "https". This ensures token security and is consistent with the Azure SDKs for other languages.

• Updated retry policy timeouts to conform to Azure guidelines.

  • The default delay between retries is changed from 4 seconds to 800ms.
  • The maximum retry delay is changed from 2 minutes to 60 seconds (one minute).

  If the original behavior is desired, customers can adjust these timeouts by changing the RetryDelay and MaxRetryDelay fields in the RetryOptions structure.

Bugs Fixed

• Fixed bug in WinHTTP client which caused the IgnoreUnknownCertificateAuthority and EnableCertificateRevocationListCheck fields to be ignored if they were passed in from TransportOptions.
• [#4206] Fixed connectivity issues in libcurl HTTP transport which can occur if a TCP connection is dropped prematurely. (A community contribution, courtesy of ahojnnes)
