- Sanitizers and Control Flow Integrity
    - Using CFI to harden WebKit and JSC
        - Needs clang with LTO and hidden visibility
        - Not running with JIT
        - Currently working internally
    - Running WebKit with other sanitizers
        - MSVC is going to ship with built in Asan support
        - WinCairo can build with clang-cl supports some sanitizers
        - Address Sanitizer bots?
            - Maybe based on gtk or wpe given better support for the sanitizers on Linux?
- CMake Improvements
    - Target based
        - Remove use of all the _LIBRARIES_INCLUDE_DIR and instead have them communicated through the target
    - Mirror Apple Build
        - Each project independently
        - Copy all headers
    - General clean-up of the build
    - Upstreamed enhancements to Make for our Platform Visual Studio integration
- JSC Improvements
    - Implemented new language features
        - Optional chaining (?.) and bullish coalescing (??)
            - Still behind runtime flag but ready anytime
        - Numeric literal separators (_)
        - Hasbang (#!)
    - Added private (JSContextPrivateRef) C++ API for unhandled promise rejections
        - Internal need for the callback
        - No objective C api at this time
    - Made various spec compliance fixes
        - Mostly concerning early errors
        - In two cases, managed to fix the spec instead!
        - ECMAScript fixes based on JSC behavior
- WinCairo Bots
    - Migrated to new EWS
        - Addressed issues with patch on Windows
            - Cause of patches failing to apply
        - Looking into AWS
            - All builds running in docker containers
            - Hoping to address scale and stability
- Downstream WebKit Port
    - Currently branched off of latest Safari release branch
        - Safari 608.1.48
    - Still have a large amount of patches downstream
        - Upstream focus has been on common code between WInCairo and PlayStation
        - Sometimes internally near deadlines things get thrown in, trying to improve things when upstreaming

    - WebKitWebDriver Binary for GTK with our socket implementation
        - Can connect to device to control web view

        - Developers use either Windows or Mac
    - This was driven by internal QA requests
        - We are interested in WPT in longer term
- Internal Build Infrastructure
    - BuildBot for internal WebKit Builds
        - Based on build.webkit.org config
        - Server hosted on AWS
        - Articfacts to S3
