3.0.0

New features:

• ⭐ Add support for Immediate Freeze (0x07), Immediate Freeze No Ack
  (0x08), Freeze-and-Clear (0x09), Freeze-and-Clear No Ack (0x10). See PR #320.
• Add support for broadcast. See PR #312.
• ⭐ Add UDP support. See PR #314.
• ⭐ Add unsolicited fixed number of retries See PR
  #323.
• ⭐ Add support for timestamp quality and g51v2 (CTO Unsynchronized). See
  PR #316.
• ⭐ Add support for TLS 1.3 (requires OpenSSL 1.1.1). See PR
  #372.

API changes:

• ⭐ Complete reorganization of the code to produce a single library.
  Properly separate the public header files from the private ones. Refactor the
  CMake to use modern practices.
• ⭐ Outstation database points are now specified using a map instead of a
  sorted array. See PR #296.
• ⭐ ICommandHandler now includes a Begin and a End callback to know
  which commands were grouped together in a single APDU. See PR
  #341.
• ⭐ ISOEHandler now includes a BeginFragment and EndFragment to help
  determine if it's a multi-fragment response or an unsolicited response. See PR
  #298.
• ⭐ When sending requests, a distinct SOEHandler can be specified to help
  associate the response with the request. To keep the old behaviour, simply
  pass the same SOEHandler on each request. See PR
  #339.
• ⭐ All public enumerations used by the library exposes a to_string and a
  from_string method. They also expose a to_type and a from_type method to
  convert to and from the underlying integer value. See PR
  #308.
• ⭐ Control Relay Output Block now expose each field individually. See PR
  #349.
• ⭐ Instead of relying on an output parameter, DNP3Manager now throws an
  exception on misconfiguration. This also includes if a server was not able to
  bind to a port. See issue
  #293 and PR
  #367.
• ❌ Remove sending data-link confirmation support. It still supports
  receiving confirmed data to interoperability. See issue
  #364 and PR
  #367.
• 🪲 TaskConfig now takes a std::shared_ptr instead of a reference. See
  issue #238 and PR
  #367.

Bindings changes:

• ⭐ Add typed flag handling in Java and C#. See PR
  #342.
• ⭐ In the Java bindings, when DNP3Manager fails, an descriptive
  exception is thrown instead of returning a null. See PR
  #367.
• ⭐ Published NuGet packages now include both x86 and x64 binaries.
• 🪲 Provide IDnpTimeSource interface in Java and C#. See issue
  #353 and PR
  #357.
• 🪲 Add typesAllowedInClass0 in Java bindings. See PR
  #360.

CI:

• 🔨 Move continuous integration to GitHub
  Actions.
• 🔨 Add automated Subset Level 2 conformance testing. The report
