This is the first release candidate for the upcoming 1.1.0 release of BIND 10. BIND 10 provides a C++ library for DNS (with python wrappers) and several cooperating daemons for providing authoritative DNS service (with in-memory and SQLite3 backends and DNSSEC support), dynamic DNS, zone transfers, forwarding, and experimental recursive name service. It also provides DHCPv4 and DHCPv6 servers and a C++ library for DHCP. Supplementary components are included for statistics collection and reporting and remote configuration and control. This release candidate includes the following changes since the previous beta. (For the full commit history, please see the git logs.) 619. [bug] jinmei b10-xfrout now uses blocking send for xfr response messages to prevent abrupt termination of the stream due to a slower client or narrower network bandwidth. (Trac #2934, git bde0e94518469557c8b455ccbecc079a38382afd) 617. [bug] marcin b10-dhcp4: Fixed a bug whereby the domain-name option was encoded as FQDN (using technique described in RFC1035) instead of a string. Also, created new class which represents an option carrying a single string value. This class is now used for all standard options of this kind. (Trac #2786, git 96b1a7eb31b16bf9b270ad3d82873c0bd86a3530) 615. [bug] jinmei b10-auth: Avoid referencing to a freed object when authoritative server addresses are reconfigured. It caused a crash on a busy server during initial startup time, and the same crash could also happen if listen_on parameters are reconfigured at run time. (Trac #2946, git d5f2a0d0954acd8bc33aabb220fab31652394fcd) The bind10-1.1.0rc1 source may be downloaded from: ftp://ftp.isc.org/isc/bind10/1.1.0rc1/bind10-1.1.0rc1.tar.gz A PGP signature of the distribution is at ftp://ftp.isc.org/isc/bind10/1.1.0rc1/bind10-1.1.0rc1.tar.gz.sha512.asc The signature was generated with the ISC code signing key which is available at https://www.isc.org/about/openpgp Installation details are documented in the BIND 10 Guide.
