  • v10.0 Changes

    🚀 Release Date: 26 November 2022

    • ➕ Added Dynamic Updates RFC 2136 security policy support to allow updates only for specified domain names and record types. This adds breaking changes to the zone options HTTP API calls. Any implementation that uses the zone options API must test with new update before deploying to production.
    • ➕ Added support for DANE TLSA RFC 6698 record type. This includes support for automatically generating the hash values using certificates in PEM format.
    • ➕ Added support for SSHFP RFC 4255 record type.
    • 👍 Implemented EDNS Client Subnet (ECS) RFC 7871 support for recursive resolution and forwarding.
    • 🚀 Updated HTTP API to accept date time in ISO 8601 format for dashboard and query logs API calls. Any implementation that uses these API must test with new update before deploying to production.
    • ⬆️ Upgraded codebase to .NET 7 runtime. If you had manually installed the DNS Server or .NET 6 Runtime earlier then you must install .NET 7 Runtime manually before upgrading the DNS server.
    • 🛠 Fixed self-CNAME vulnerability reported by Xiang Li, Network and Information Security Lab, Tsinghua University which caused the DNS server to follow CNAME in loop causing the answer to contain couple of hundred records before the loop limit was hit.
    • ⚡️ Updated DNS Apps framework with IDnsPostProcessor interface to allow manipulating outbound responses by DNS apps.
    • NO DATA App: Added new app to allow returning NO DATA response in Conditional Forwarder zones to allow overriding existing records from the forwarder for specified record types.
    • 👍 DNS64 App: Added new app to support DNS64 function RFC 6147 for use by IPv6 only clients.
    • ⬆️ Advanced Blocking App: Upgraded the app code to use less memory when same block lists are used across multiple groups.
    • ⬆️ Geo Continent App, Geo Country App, and Geo Distance App: Upgraded the apps to support EDNS Client Subnet (ECS) RFC 7871.
    • ⬆️ Split Horizon App: Upgraded the app to add 1:1 IP address translation support. This allows mapping external/public IP address to internal/private IP address such that clients in private network can access local services using internal/private IP addresses.
    • ➕ Added support for Domain Search DHCP option RFC 3397
    • ➕ Added support for CAPWAP Access Controller DHCP option RFC 5417.
    • ➕ Added DHCP Scope option to disable DNS updates.
    • ➕ Added DHCP Scope option to support domain name for NTP option such that the DHCP server will automatically resolve the domain names and use the resolved IP addresses with the NTP option.
    • 🛠 Multiple other minor bug fixes and improvements.

  • v9.1 Changes

    🚀 Release Date: 9 October 2022

    • ➕ Added Dynamic Updates RFC 2136 support. This allows using tools like nsupdate, allow 3rd party DHCP servers to update DNS records, and use certbot certbot-dns-rfc2136 plugin for automatic TLS certificate renewal using DNS challenge.
    • ⚡️ Updated dashboard to display main chart using client's local time instead of server's local time.
    • 🛠 Fixed bug that caused error while adding new secondary zone.
    • 🛠 Multiple other minor bug fixes and improvements.

  • v9.0 Changes

    🚀 Release Date: 24 September 2022

    • ➕ Added multi-user role based access support. This allows creating multiple users and multiple role based groups with permission based access controls.
    • ➕ Added support for non-expiring API tokens to use with automation scripts.
    • ➕ Added zone level permissions support to allow access only to selected users or group members.
    • ⚡️ User profile options available to update each user's session timeout values.
    • 🚀 HTTP API: The API has been updated extensively keeping backward compatibility. Any implementation that uses the API must test with new update before deploying to production. Using the non-expiring API tokens is recommended.
    • ⚡️ Updated Conditional Forwarder zones to support APP records to allow using DNS Apps in these zones.
    • ⚡️ Option added in Settings to stop block list URL automatic update.
    • 🚀 DNS Apps: There is a breaking change in the IDnsAppRecordRequestHandler.ProcessRequestAsync() method. If you have any custom DNS app deployed, you need to recompile it with the latest DnsServerCore.ApplicationCommon.dll before updating to this new release.
    • ⚡️ DNS Apps now support automatic updates. The DNS server will check for updates and install them automatically every 24 hours.
    • 🔧 Split Horizon App: Added feature to configure collection of networks to use with APP record data.
    • Wild IP App: Added new DNS App that returns a response A or AAAA queries with the IP address that is embedded in the subdomain name of the query. This app works similar to sslip.io.
    • 🛠 Fixed minor issues in DNSSEC validation for DNAME responses and for wildcard NO DATA responses.
    • ⚡️ DHCP scopes now support updating DNS records in both Primary and Forwarder zones.
    • 👍 DHCP scopes now support blocking dynamic allocations to devices with locally administered MAC address.
    • 🛠 Multiple other minor bug fixes and improvements.

  • v8.1.4 Changes

    🚀 Release Date: 3 July 2022

    • 🛠 Fixed issue in recursive resolution that caused DNSSEC validation to fail in cases when the name server responds with out-of-bailiwick records.
    • 🐎 Updated recursive resolver to update addresses async for all NS records to improve performance.
    • 🛠 Multiple other minor bug fixes and improvements.

  • v8.1.3 Changes

    🚀 Release Date: 11 June 2022
