Despite my inconsistencies posting, Echo does get regular updates and is in active use.

A long overdue summary is here. This covers work merged into default over the last couple of months.

Switched to C++17 by default

As usual the default base version bump lags to ensure support is available in toolchains. There are C++20 projects using Echo so you can further bump this up for your projects.

• CMakeLists sets this if the standard isn't specified
• Linux tested
• Dependencies for other platforms vary and will be updated over time.

Networking

• Added support for listening management
• A listener object is returned on call to NetworkManager::Listen() which can be used to cancel the listen request. Legacy interface is still available.
• Fixed a race causing a deadlock on connection cleanup of BoostASIONetworkSystem. This was a result of an earlier bugfix and never spotted due to the specific use case not being used anywhere until recently
• Removed logging that suggested an error during normal operation of disconnect in SocketNetworkSystem
• Sped up network tests
• Added raw data sending and receiving for Connections.
  • This can be used by calling Connection::SetRawDataHandler()
  • Switching to this mode shifts full responsibility of data management to the caller immediately. Packet callbacks aren't used in this mode.
• Merged typescript networking support

Configuration

• Added option for configuration to set rather than add when parsing.

This can be set with SetParsingSetsNotAdd() or overridden with configuration.overwrite=true|false[,persist]
This has probably been the one main limitation of Configuration of which multiple work arounds have been used in the past.

GUI

• Text supports a template string which can include a $0 which is set to the supplied text value. For example:

"textTemplate": "Number of trees: $0"

and when

// Templated auto conversion
guiText->SetText(1234);

results in:

Number of trees: 1234

edepbuild

• Added Powershell support
  • Includes downloading a local cmake automatically if cmake isn't available on the command line
• edepbuild is available on GitHub

Packaging

• Added cpack options to allow building a deb with:

cd build
cpack ..

Misc

• Fixed various compiler warnings
• Templates were updated to capnp from protobuf
• Resource conversion scripts updated to detect non-e-prefix files.
• Updated devkitpro setup script
