107 | | - - ### Bugfixes |
108 | | - - Honor wildcard `nonProxyHosts` entries in CRT-based HTTP clients (`AwsCrtHttpClient`, `AwsCrtAsyncHttpClient`, and the S3/CRT client). Previously a `*.suffix` wildcard or a bare `*` from `http.nonProxyHosts`/`no_proxy` was silently ignored, so matching hosts were routed through the proxy instead of bypassing it. Supported forms are an exact host, a `*.suffix` wildcard (matches the domain and its subdomains), a single `*` for all hosts, and CIDR ranges. Entries must not contain surrounding whitespace. |

123 | | - - ### Features |

Previously an entry with a leading or trailing space was treated as part of the host name and never matched, so the host was routed through the proxy instead of bypassing it. |
145 | | - |
146 | | -## __Apache HTTP Client__ |
147 | | - - ### Bugfixes |
148 | | - - Trimmed surrounding whitespace from `nonProxyHosts` / `no_proxy` entries so comma- or pipe-separated values with spaces (e.g. `no_proxy=a.com, *.foo.com`) are honored.
