NSD vs Manticore Search: at a glance
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 Manticore Search?
Manticore keeps patching 31.x, now fixing a FREEZE crash and a DocID ordering bug.
Manticore Search's 31.x tags remain fixes rather than features. 31.0.7 restored string COUNT(DISTINCT) speed after a collation fix had doubled it to 2.4 s, and 31.0.18 bumped the Buddy sidecar for PHP 8.5. 31.0.19 fixes deferred real-time kills that sorted document IDs as signed numbers, and 31.0.21 stops FREEZE from crashing when it includes a distributed table.

NSD
5.0DEVOPS
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.
Manticore Search
5.0DEVOPS
Manticore keeps patching 31.x, now fixing a FREEZE crash and a DocID ordering bug.
◆ Current state
Manticore Search's 31.x tags remain fixes rather than features. 31.0.7 restored string COUNT(DISTINCT) speed after a collation fix had doubled it to 2.4 s, and 31.0.18 bumped the Buddy sidecar for PHP 8.5. 31.0.19 fixes deferred real-time kills that sorted document IDs as signed numbers, and 31.0.21 stops FREEZE from crashing when it includes a distributed table.
◆ Where it's heading
The 31.x line is in steady correctness work, with several tags a week and each fixing one edge case in real-time tables, backups or query paths. No feature work has shown up in the feed since 31.0 began.
◆ Prediction
Expect more single-fix 31.0.x tags; the entries give no sign of when the next feature release lands.
