The regex at

CiviProxy/de.systopia.civiproxy/CRM/Admin/Form/Setting/ProxySettings.php

Lines 108 to 113 in bbf5c3c

	$result = preg_match("/<p id=\"version\">CiviProxy Version ([0-9]+\.[0-9]+|[0-9]+\.[0-9]+\.[0-9]+)<\/p>/", $response, $output_array);
	if ($result === FALSE || $result === 0){
	return array('is_error' => 1, 'message' => sprintf(ts('Error: failed to parse version information'), $url));
	}else{
	return array('is_error' => 0, 'version' => $output_array[1]);
	}

does not match dev releases such as "CiviProxy Version 0.6-dev" which is the current latest version.

That's a good point. @codebymikey Care to provide a PR?

Made a PR, the regex could be simplified to (([0-9]+(\.[0-9]+){1,2})(?:-[0-9A-Za-z-]+)?), but that's up to you.
