v0.11.4

• Changed
  • Internet connectivity checks can now take domain names. Previously only IP
    addresses were supported. This change lets you add your own servers to the
    list since those servers may be more reliable indicators of Internet access
    in highly firewalled locations. A section on this was added to the README.md
    with an example.

v0.11.3

• Changed
  • Don't downgrade the connection status on DHCP renewals. Previously, if there
    was a DHCP renewal, the connection status could go from "Internet-connected"
    "LAN-connected". The logic was that IP address and router changes may make
    the Internet unreachible. The new logic is to assume that the device is
    still Internet-connected and let the connectivity checker downgrade the
    status should it be necessary. This not only removes a status hiccup, but
    also fixes a race between the connectivity checker upgrading the connection
    and the DHCP notification degrading it.
  • Improve the VintageNet.info error when the :vintage_net application
    stops.

v0.11.2

• Added
  • Added VintageNet.RouteManager.refresh_route_metrics/0 to recompute the
    routing table metrics. This is useful if you're supplying your own
    :route_metric_fun and something has changed to make it return a different
    prioritization. Thanks to @LostKobrakai for this feature.

v0.11.1

• Changed
  • The DNS server ordering is more deterministic now. Global DNS servers are
    guaranteed to be listed first and in the order specified. VintageNet will
    also try to preserve the ordering of DNS servers learned through DHCP. This
    isn't always possible, though. This fixes a hard-to-find error where an
    a difference in DNS server orderings between to device locations led to
    different behavior.
  • Use VintageNet.ConnectivityChecker.* in VintageNet. The connectivity
    checker module change was half made in v0.11.0, but the old module name
    was kept in a couple places to avoid breaking unit tests in other VintageNet
    libraries. Now it's completely converted. This doesn't affect runtime. Code
    that references the previous names will still get deprecation warnings like
    in v0.11.0.

v0.11.0

This release should be a safe update for most users. Many routing table and
internet connectivity check modules were updated, but the changes were primarily
in private APIs.

• Added

  • Support for detecting Internet connectivity on an interface passively by
    watching tx and rx stats on TCP sockets. For example, if you have a
    long-lived TCP connection (like for MQTT), the keepalive messages will
    bump tx and rx counters that will let VintageNet skip testing the connection
    for connectivity. This reduces traffic on metered connections.
  • Support for completely overriding route metric calculation. You can now
    specify a :route_metric_fun instead of using the DefaultMetric
    calculator for determining which network interface preferences.
  • VintageNet property change events now come with timestamps. These are useful
    for computing state durations and other time-based stats for events.

• Removed

  • Support for setting route prioritization order. This feature was more
    limiting that it originally looked. The new :route_metric_fun is more
    straightforward since it lets you explicitly specify orderings and lets
    decisions be made based on more input data.

• Changed

  • VintageNet.Interface.InternetConnectivityChecker is now
    VintageNet.Connectivity.InternetChecker. Please update any references. Old
    references will continue to work, but give a deprecation message at runtime.

v0.10.5

This release only contains build system and hex package update. It doesn't
change any code and is a safe update.

v0.10.4

• Bug fixes
  • DHCP renewals would bounce connection status from :internet to :lan and back
    even when the IP address, subnet, and default gateway didn't change. This
    could cause a network connectivity hiccup that would happen every 24 hours
    (a common DHCP lease time). A fix was added to assume internet connectivity
    was maintained if the DHCP renewal didn't change IP parameters.

v0.10.3

• Bug fixes
  • Fix regression with tracking udhcpd lease notifications. Leases
    notifications were being ignored, so if you were monitoring leases to see
    who was connected, then you wouldn't see any connections without this fix.
    Thanks to Jon Thacker for reporting this issue.
  • Fix crashes when the application config is invalid. While the configurations
    were incorrect and needed to be fixed, it was harder to debug than it should
    have been. This release logs messages on invalid configs and carries on
    bringing up left that's valid. Thanks to Matt Ludwigs for this fix.

v0.10.2

This release officially removes support for Elixir 1.7 and Elixir 1.8. It turns
out that those versions wouldn't have worked in v0.10.0 due to a dependency that
was added.

• Improvements
  • Add VintageNet.reset_to_defaults/1 so that it's easy to reset a network
    interface's configuration to what it would be if VintageNet.configure had
    never been called. The previous "easy" way of doing this was to erase the
    persisted configuration file and reboot.
  • Clean up interface reachability handling (disconnected vs. lan-connected vs
    internet-connected). There was an issue where the status was out of sync due
    a bug in a technology implementation. This is harder to do now. IMPORTANT:
    if you have a custom technology implementation, calling
    VintageNet.RouteManager.set_connection_status is sufficient. You no
    longer need to update the status property for your interface. This is not a
    common need.

v0.10.1

• Improvements
  • There's now an :additional_name_servers global configuration key so that
    it's possible to force name servers to always be in the list to use. For
    example, if you don't trust that you'll always get good name servers from
    DHCP, you can add a few public name servers to this list.
  • /etc/resolv.conf now has nice comments on where configuration items come
    from. Thanks to Connor Rigby for this idea and implementation.
