Changelog
---------
+v4.1.0
+======
+
+ - NEW: travis / appveyor / bintray are replaced by Sai
+ https://libwebsockets.org/sai/ which for lws currently does 167 builds per
+ git push on 16 platforms, all self-hosted. The homebrew bash scripts used
+ to select Minimal examples are replaced by CTest. Platforms currently
+ include Fedora/AMD/GCC, Windows/AMD/mingw32, Windows/AMD/mingw64, Android/
+ aarch64/LLVM, esp-idf (on WROVER-KIT and HELTEC physical boards), Fedora/
+ RISCV (on QEMU)/GCC, CentOS8/AMD/GCC, Gentoo/AMD/GCC, Bionic/AMD/GCC,
+ Linkit 7697, Focal/AMD/GCC, Windows (on QEMU)/AMD/MSVC,
+ Focal/aarch64-RPI4/GCC, iOS/aarch64/LLVM and OSX/AMD/LLVM.
+
+ - NEW: The single CMakeLists.txt has been refactored and modernized into smaller
+ CMakeLists.txt in the subdirectory along with the code that is being managed
+ for build by it. Build options are still listed in the top level as before
+ but the new way is much more maintainable.
+
+ - NEW: Captive Portal Detection. Lws can determine if the active default
+ route is able to connect to the internet, or is in a captive portal type
+ situation, by trying to connect to a remote server that will respond in an
+ unusual way, like provide a 204.
+
+ - NEW: Secure streams: Support system trust store if it exists
+ Build on Windows
+ Support lws raw socket protocol in SS
+ Support Unix Domain Socket transport
+
+ - NEW: Windows: Support Unix Domain Sockets same as other platforms
+
+ - NEW: Windows: Build using native pthreads, async dns, ipv6 on MSVC
+
+ - NEW: lws_struct: BLOB support
+
+ - NEW: lws_sul: Now provides two sorted timer domains, a default one as
+ before, and another whose scheduled events are capable to wake the system from suspend
+
+ - NEW: System Message Distribution: lws_smd provides a very lightweight way
+ to pass short messages between subsystems both in RTOS type case where the
+ subsystems are all on the lws event loop, and in the case participants are in
+ different processes, using Secure Streams proxying. Participants register a bitmap
+ of message classes they care about; if no particpant cares about a particular message,
+ it is rejected at allocation time for the sender, making it cheap to provide messages
+ speculatively. See lib/system/smd/README.md for full details.
+
+ - NEW: lws_drivers: wrappers for SDK driver abstractions (or actual drivers)
+ See lib/drivers/README.md, example implementations
+ minimal-examples/embedded/esp32/esp-wrover-kit
+ - generic gpio
+ - generic LED (by name) lib/drivers/led/README.md
+ - generic PWM, sophisticated interpolated table
+ sequencers with crossfade
+ - generic button (by name), with debounce and press classification
+ emitting rich SMD click, long-click, double-click,
+ down, repeat, up JSON messages
+ lib/drivers/button/README.md
+ - bitbang i2c on generic gpio (hw support can use same
+ abstract API)
+ - bitbang spi on generic gpio (hw support can use same
+ abstract API)
+ - generic display object, can be wired up to controller
+ drivers that hook up by generic i2c or spi,
+ generic backlight PWM sequencing and
+ blanking timer support
+ - generic settings storage: get and set blobs by name
+ - generic network device: netdev abstract class with
+ WIFI / Ethernet implementations
+ using underlying SDK APIs;
+ generic 80211 Scan managements
+ and credentials handling via
+ lws_settings
+ This is the new way to provide embedded platform
+ functionality that was in the past done like
+ esp32-factory. Unlike the old way, the new way has no
+ native apis in it and can be built on other SDK / SoCs
+ the same.
+
+ - NEW: Security-aware JWS JWT (JSON Web Tokens) apis are provided on top of the existing
+ JOSE / JWS apis. All the common algorithms are available along with some
+ high level apis like lws http cookie -> JWT struct -> lws http cookie.
+
+ - REMOVED: esp32-helper and friends used by esp32-factory now lws_drivers
+ exists
+
+ - REMOVED: generic sessions and friends now JWT is provided
+
v4.0.0
