Hi, NSD 4.4.0 is available: https://nlnetlabs.nl/downloads/nsd/nsd-4.4.0.tar.gz sha256 cfcd6fdd99344ca5a7ef7c2940c241bcef471fc3252ba3dcbd4c57e0638e8836 pgp https://nlnetlabs.nl/downloads/nsd/nsd-4.4.0.tar.gz.asc This release changes the memory allocation for outgoing zonetransfers, and this reduces the memory footprint. The defaults for the amounts are the same as before, but there are config options to configure the memory usage. There are also bug fixes. 4.4.0 ===============FEATURES: - Merge #193: Lower memory usage of the XFRD process by default. Instead of preallocating all elements, they are allocated when used. There are options for managing the memory usage, defaults are the same as before. xfrd-tcp-max sets the number of sockets for tcp connections that xfrd can make to download zone contents. And xfrd-tcp-pipeline the number of simultaneous transfers over the same connection. BUG FIXES: - Fix #200: nsd-checkzone succeeds even with incorrect serial in SOA record. - Merge #204 from jonathangray: correct some spelling mistakes. - Fix to change file mode before changing file owner for the nsd-control unix socket file. - Fix to document nsd-checkzone -p in the man page for nsd-checkzone. - Fix #206: build with --without-ssl fails. - Merge #207 Sync nsd-control-setup with unbound-control-setup to generate certificates with SANs. - Fix unit tests for nds-control-setup exit code and the xfrd-tcp-max default. Best regards, Wouter
