=item 0.62 - Dec 02, 2001

accurate tallying of sent, good, and failed requests; fixed incorrect
total_requests_sent(), total_responses_received() methods, and added new
total_responses_failed() method and per-run sent_requests(), good_responses(),
and failed_responses() methods

added support for global and per-url/per-run time limits

updated header files from Apache 1.3.22 src/include/

added support for HTTP HEAD requests per-url/per-run

fixed a small bug that sent a GET request for a defined-but-empty string value
in postdata() array; now it sends a POST request with Content-length: 0

added support for HTTP KeepAlive feature on global or per-url/per-run basis

=item 0.61 - Oct 23, 2001

new methods ready_to_execute() and prepare_for_execute() to
eliminate segmentation faults due to configuration errors

new feature that allows adding arbitrary extra HTTP request headers

fixed bug that caused segmentation fault when custom Content-type: headers
were specified for POST

removed 512 byte hard-coded maximum size of HTTP requests; now requests can be
arbitrarily large

regression methods that returned arrayrefs now can be passed an optional index
parameter to cause them to return the specified value out of the array

fixed bug in ApacheBench.xs reset_request() for null cookies - bug
caused ApacheBench-Perl not to work properly with virtual hosts because
a null "\0" char was embedded in the HTTP request before the Host: line
(spotted by Raju M. Daryanani <rajumd@geocities.com>)

store all HTTP requests sent to server, accessed by request_body() method

improved documentation for postdata() method, on suggestion
from Scott Croco <scott.croco@lucasfilm.com>

=item 0.52 - Nov 25, 2000

added debugging printf() statements which can be turned on by defining
