    Release 1.4.0

    This release adds a new module `input.zmmpcap` to read compressed PCAPs
    using `mmap()`, changes how `core.thread` push/pop, removes signal
    blocking and squashes a few bugs.

    For `core.thread`, the `push()`/`pop()` now uses `double` instead of
    `int64_t` to match the conversion table of LuaJIT and to support
    floating point numbers.

    Updates:
    - `examples/dumpdns`:
      - Add support for reading PCAPs using `mmpcap` or `zmmpcap`
      - Add support for reading PCAPs from stdin
    - `zpcap`: Add support for reading zlib/lzma compressed PCAPs

    Fixes:
    - Fix #234: Remove signal blocking
    - Fix #233: floating point numbers not supported by `dnsjit.core.thread` push/pop
    - Fix a potential memory leak in trie
    - `zpcap`: Fix incorrect check if having enough to read

    Release 1.3.0

    This release adds `core.object.dns:reset()` to reset DNS objects so they
    can be reused correctly.

    Example scripts have been updated to reflect this along with correctly
    setting `includes_dnslen` for TCP packets.

    New example converter `pcap2tcpdns` added that can be used to create bin
    files for replaying with `dnsperf -B`.

    Release 1.2.0

    This release adds development files and autotool examples for C/Lua
    modules or stand-alone tools for dnsjit.

    In `examples/` you'll now also find:

    - `modules/input-example`
      This input example is based on `dnsjit.input.zero` which was a testing
      modules during the early days of dnsjit.
      It's a C module that generates empty objects for the receiver.

    - `modules/filter-example`:
      This filter example is C module that counts the number of objects
      passed to it before sending it to the receiver.

    - `modules/output-example`:
      This output example is based on `dnsjit.output.null` which was a testing
      modules during the early days of dnsjit.
      It's a C module that will just discard objects it receives.

    - `modules/lib-example`:
      This example Lua module takes two `core_timespec_t` C objects and gives
      the duration between them as a string.

    - `stand-alone-tool`:
      This example is based on `test_pcap_read.lua` and `test_throughput.lua`
      which was previous located in `examples/`.
      There are two installable Lua programs and shows how to depend on
      a dnsjit version, depend on specific dnsjit modules and how to run
      tests using `make test`.

    All these examples can easily be copied and renamed to build and
    distribute your own dnsjit modules and tools, using autotool for
    `configure`, `make` and `make install`.

    Development files will also be installed, or can be installed via
    `dnsjit-dev`/`dnsjit-devel` packages. All C headers have been prefixed
    with `dnsjit/` (for example `#include <dnsjit/version.h>`).

    Thanks to this new setup, the module `output.dnssim` has been moved out
    from dnsjit's repository and placed in DNS shotgun's:

      https://gitlab.nic.cz/knot/shotgun/-/tree/master/replay/dnssim

    This will help CZ.NIC to maintain and release both the module and tool
    at the same time.

    New modules:
    - Added `input.zpcap`, module for reading LZ4/ZSTD compressed PCAPs
    - Added `core.loader`, module for loading C modules using LuaJIT's `ffi` interface and `package.cpath`
    - Added `core.file` with `core_file_exists()`, a C function to check if a file exists

    Other changes:
    - Add `<dnsjit/version.h>` for `DNSJIT_MAJOR_VERSION`, `DNSJIT_MINOR_VERSION`, `DNSJIT_PATCH_VERSION`
    - `dnsjit`: Remove version print on start
    - `dnsjit.input.zero`: Will `require("example.input.zero")` for backwards compatibility
    - `dnsjit.output.null`: Will `require("example.output.null")` for backwards compatibility
    - `core/timespec`: Add `:max_init()`, return a new object with maximum values set for seconds and nanoseconds.
    - `output/pcap`:
      - Update `open()` man-page, indicate usage of `pcap_dump_open()`
      - Add `have_errors()` to check for write errors during/after dumping
    - `input.fpcap`: Add `fadvise_sequential()` to advise sequential read of the file
    - `examples/dumpdns.lua`: Add support for dumping compressed PCAPs

    Bugfixes:
    - `lib/getopt`: Fix short options, error if length is not 1
    - `core/timespec`: Fix typo in struct documentation

    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
