* [BREAK] merged lp:~mvo/apt/history
- this writes a /var/log/apt/history tagfile that contains details from the transaction (complements term.log) * methods/http.cc: - add cache-control headers even if no cache is given to allow adding options for intercepting proxies - add Acquire::http::ProxyAutoDetect configuration that can be used to call a external helper to figure out the proxy configuration and return it to apt via stdout (this is a step towards WPAD and zeroconf/avahi support) * abicheck/ - add new abitest tester using the ABI Compliance Checker from http://ispras.linuxfoundation.org/index.php/ABI_compliance_checker * Change the package index Info methods to allow apt-cache policy to be useful when using several different archives on the same host. (Closes: #329814, LP: #22354)
