-%changelog -* Wed Feb 03 2021 Jerry Lundström 1.1.0-1 -- Release 1.1.0 - * This releases adds a new module for handling Base64 URLs and new calls - for error handling and opening PCAPs using file descriptors, along with - a bug fix in `lib.getopt` and other changes. - * The `dnssim` module has also gotten its own version and changelog, this - is to prepare it for being moved outside of dnsjit's repository in the - future. - * New modules, calls, features: - - New `lib.base64url`: Utility library to convert data to base64url format - - `core.log`: New call `Log.errstr()`: Convert error number to its text representation - - `input.fpcap`: New call `Fpcap.openfp()`: Open a PCAP file for processing using a file descriptor, for example `io.stdin` - - `output.dnssim`: Support for DNS-over-HTTPS - * Bug fixes: - - `lib.getopt`: Fix bug where `-` and `--` could not be used as arguments to options - * Other changes: - - Fix typo in configure help text - - Add coverage - - `filter.ipsplit`: Extend PRNG modulus to 2^31, new implementation is the same as glibc's `rand()` - - `lib.ip`: Fix typo in documentation - - `output.dnssim`: - - This module now has it's own changelog - - Updated to v20210129 - - Depend on libhttp2 for dnssim DNS-over-HTTPS capabilities - - `output.pcap`: Log libpcap error when failing to open - - SUSE packages now depend on moonjit because of lack of LuaJIT support - * Commits: - d001ccb m4 - 4b63bce output/dnssim: add changelog - 7355810 output/dnssim: add version checks - 95fa6a9 input pcap/fpcap, getopt - 99c3d9f
