What is NSD?

NSD's 4.15 line is being shaped by outside researchers' bug reports.

NLnet Labs shipped two NSD releases in October. 4.15.3 fixed four CVEs in the simdzone zone-file parser that only crafted zone files can trigger, a risk mainly for multi-tenant setups where third parties feed zone data. 4.15.4 adds a report-channel EDNS option, a catalog-group-pattern setting that limits which patterns catalog member zones may use, and the UNECE and ISO record types, alongside a long list of fixes credited to researchers at Palo Alto Networks and Tsinghua University.

What is Sanity?

Sanity's MCP server now explains failed validations and stops skipping them.

Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

NSD vs Sanity: editorial side-by-side

N
NSD
DEVOPS
5.0

NSD's 4.15 line is being shaped by outside researchers' bug reports.

◆ Current state

NLnet Labs shipped two NSD releases in October. 4.15.3 fixed four CVEs in the simdzone zone-file parser that only crafted zone files can trigger, a risk mainly for multi-tenant setups where third parties feed zone data. 4.15.4 adds a report-channel EDNS option, a catalog-group-pattern setting that limits which patterns catalog member zones may use, and the UNECE and ISO record types, alongside a long list of fixes credited to researchers at Palo Alto Networks and Tsinghua University.

◆ Where it's heading

Most of the 4.15 cycle is reactive: four security or bug-fix releases since August, with outside researchers finding parser overflows, crashes on malformed catalog zones and IXFR edge cases. Features still arrive, and at least one, catalog-group-pattern, was suggested by a researcher who also reported bugs. Catalog zones and zone-file parsing are where the attention is concentrated.

◆ Prediction

Expect more fixes in catalog zone and zone-file parsing as outside fuzzing continues, likely in another 4.15 patch. The entries give no sign of a 4.16 feature release.

S
Sanity
DEVOPS
6.3

Sanity's MCP server now explains failed validations and stops skipping them.

◆ Current state

Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

◆ Where it's heading

Sanity is making the agent-facing parts dependable: the MCP server is getting the error codes and validation rules a production client needs. Access visibility for tokens and members follows the same push to let teams audit what automated clients do.

◆ Prediction

Expect more MCP server point releases around validation and Knowledge Base commands, and more usage data on tokens and agents in the console.
