Release 1.12: Net\Browser API stabilization

Release highlights

• Net\Browser basic API is stable and unlikely to change in the future;
• Improved CurlException message construction;
• Net\Url documentation improvements.

Net\Browser

Turned out, CURLOPT_HTTPGET/CURLOPT_POST/CURLOPT_PUT is a request TYPE.
Yes, it implies default method name, but you can change it with CURLOPT_CUSTOMREQUEST
(a method NAME, which does not affect request TYPE).

• CURLOPT_HTTPGET performs a body-less request;
• CURLOPT_PUT performs a request with body taken from stream resource;
• CURLOPT_POST performs a request with body provided as value of a variable,
  if the variable given as an array of values, it is further formatted
  to conform to the [RFC 7578].

CurlException

After catching empty curl_error() return on an obvious cURL error, it came to the realization, that curl_error() returning an error message text, while curl_strerror(curl_errno()) returning textual equivalent of error code.

Net\Url

Improved documentation of some more obscure test cases and fixed typo(s).
