## MaraDNS roadmap

### MaraDNS 1.2

I released MaraDNS 1.2 on December 21, 2005.

Document on transitioning from 1.0 to 1.2.

MaraDNS 1.2 has the following new features over 1.0:

- MaraDNS can now run with only a single three-line configuration file.
- Expanded and improved documentation.
- A partial native Win32 port has been done; basic MaraDNS functionality is now available on Windows.
- Full Y2038 compliance; on systems with a 32-bit timestamp, MaraDNS will happily run until 2106 or so.
- A tool, called `duende` that can daemonize MaraDNS or any other non-daemonizing program, outputting the program's standard output to syslog.
- The ability to bind to multiple IP addresses.
- A new zone file format that works side-by-side with the MaraDNS 1.0 zone file format.
- A Perl tool for converting csv1 (older) zone files to csv2 (newer) zone files. Note that MaraDNS continues to parse csv1 zone files; this tool is here for people who want to transition to the enhanced csv2 zone files.
- Full support for processing DNS records over ipv4 TCP.
- Better RFC compliance: Have the rcode in the DNS header for a reply reflect whether we have any records for the host name in question.
- The addition of a `+=` operator to the mararc file parser, so that long strings may be split up.
- It is now possible to have a default zonefile with stars at the end of hostnames
- It is possible to compile the server without recursive support, making the maradns binary 20% smaller and not needing to be linked to the pthread library.
- There is a special DOS survival mode which resoves hostnames as quickly as possible at the expense of not supporting some DNS features (such as CNAME records or star records)
- MaraDNS now has authoritative-only UDP ipv6 support. AAAA records are supported in csv2 zone files, and it is possible to run MaraDNS on an ipv6 address.
- Cname records now point back for any record type, not just A records in the authoritative half.

I have added the following features to the post-1.2.00 releases of MaraDNS:

- Optional strict RFC-compliant handling of star records.
- Added special record which sets up both forward and reverse DNS lookup for a given IP.
- Added limited remove administrative features (disabled by default), and restricted all queries that give internal informaiton about MaraDNS to a list of IPs specified by the admin.
- Ability to customize the case of informing the DNS stub resolver how to handle the case of being unable to contact any remote servers.
- Daniel Zilli has translated all of Mara's documentation in to Brazilian Portuguese.

My next plan for the 1.2 branch is to add the ability to query all of the servers for a given zone multiple times before giving up. I also plan on eventually rewriting MaraDNS in C++.
