- On-demand UDP Faces now report remaining lifetime (expirationPeriod)
- -r to retrieve RIB information
Improved nfd-status-http-server
- HTTP server now presents status as XSL-formatted XML page
- XML dataset and formatted page now include certificate name of the corresponding NFD (Issue #1807)
Several fixes in ndn-autoconfig tool (Issue #1595)
Extended options in nfdc:
- -e to set expiration time for registered routes
- -o to specify origin for registration and unregistration commands
Enable all-faces-prefix'' option in ``nfd-autoreg to register prefix for all face (on-demand and non-on-demand) (Issue #1861)
Enable processing auto-registration in nfd-autoreg for faces that existed prior to start of the tool (Issue #1863)
Build
- Enable support of precompiled headers for clang and gcc to speed up compilation
