fping 5.0 (2020-08-05)
======================

## Incompatible Changes

- In non-quiet loop and count mode, a line is printed for every lost packet
  (#175, thanks @kbucheli):

  ```
  $ fping -D -c2 8.8.8.8 8.8.8.7
  [1596092373.18423] 8.8.8.8 : [0], 64 bytes, 12.8 ms (12.8 avg, 0% loss)
  [1596092374.18223] 8.8.8.7 : [0], timed out (NaN avg, 100% loss)
  [1596092374.18424] 8.8.8.8 : [1], 64 bytes, 12.3 ms (12.5 avg, 0% loss)
  [1596092375.18344] 8.8.8.7 : [1], timed out (NaN avg, 100% loss)

  8.8.8.8 : xmt/rcv/%loss = 2/2/0%, min/avg/max = 12.3/12.5/12.8
  8.8.8.7 : xmt/rcv/%loss = 2/0/100%
  ```

- The returned size in bytes now always excludes the IP header, so if before it
  reported '84 bytes' e.g. when using 'fping -l', now it reports '64 bytes'.
  This is to make the reported size consistent with ping(8) from iputils and
  also with fping when pinging a IPv6 host (which never included the IPv6
  header size).

## New features

- The number of sent pings is only counted when the pings are received or have
  timed out, ensuring that the loss ratio will be always correct. This makes it
  possible, for example, to use loop mode (-l) with interval statistics (-Q)
  and a timeout larger than period, without having the issue that initially
  some pings would be reported as missing (#193)

- Improved precision of measurements from 10us to 1us (#136, thanks @tycho)

## Bugfixes and other changes

- The reported size of received packets is now always correct on Linux even for
  packets > 4096 bytes (#180)

- Travis CI automated testing now also macos testing and additional ubuntu
  distributions (#196)
