Bugfixes
Fix for a security vulnerability on Windows (CVE-2021-36753). Prior to this release, bat would execute programs called less/less.exe from the current working directory (instead of the one from PATH) with priority. An attacker might be able to use this by placing a malicious program in a shared directory where the user would execute bat. bat users on Windows are advised to upgrade to this version. See #1724 and #1472 (@Ry0taK).
