Beta 2	13 January, 2018	Fix Anemone not recognising themes Fix black screen when jailbreaking with tweaks enabled
Beta 3	13 January, 2018	Unlock all NVRAM variables (including setting boot-nonce) [thanks stek29] Add support for binaries with SHA1 hashes (so existing dylibs work fine, but executables will need the entitlement) [thanks stek29] Clean up some garbage files that were present from previous build (yay macOS resource forks and .DS_Store) Hopefully fix the app icon not displaying on iPhones Significantly speed up the rejailbreak process
Beta 3-2	14 January, 2018	Don't unlock NVRAM variables due to the patch crashing some devices.
Beta 3-3	14 January, 2018	Fix the NVRAM patching crashing due to the memory page being unmapped (thanks Siguza)
Beta 4	14 January, 2018	Disable NVRAM patching as it still appears to be unstable Make amfid patch more reliable so that more dylibs can be run properly Add a "shim" so existing substrate tweaks can use libsubstitute without modifications
Beta 4-2	14 January, 2018	Fix a symlink that would prevent some substrate extensions from working with libsubstitute
Beta 5	14 January, 2018	Fix an issue in the substrate shim where substitute could crash if tweaks tried hooking nonexistent selectors Fix an issue with the dylib loader dragging UIKit (and all its tweaks) into every single daemon Make jailbreakd more robust with input struct size check enforcement
Beta 6	16 January, 2018	Add a working launchctl for loading launch daemons (thanks nullpixel) Load dropbear as a launch daemon & fix zombie process issue (thanks nullpixel) Set kernel task as host special port #4 (thanks stek29)
Beta 6-2	17 January, 2018	Fix kernel memory leak in entitlement injector
Beta 6-3	18 January, 2018	Use host special port #4 to get tfp0 in jailbreakd (thanks n_triangle_dev) Add jailbreakd as a launchd service so it gets restarted if it dies (thanks n_triangle_dev)
Beta 6-4	20 January, 2018	Don't make jailbreakd rely on pidlistuptrs bug (thanks stek29) log dylib load errors in SBInject (thanks stek29) Clean up launchd payloads (thanks stek29) Load dylibs alphabetically from SBInject (thanks c0ldra1n) Check for jailbreakd start before reloading backboardd Make rejailbreaking significantly faster
Beta 7	23 January, 2018	amfid now gets re-patched if it ever gets killed (stek29 and coolstar) clean up amfid patch (stek29) Add 3d touch shortcut for jailbreaking (ca13ra1)
Beta 8	26 January, 2018	Sandbox mitigations are now in place so /Library, /private/var/mobile/Library/Preferences and /bootstrap are now accessible to all processes! (stek29, coolstar) Workaround sandbox mitigations not taking place on apps' first launch (coolstar) Improve reliability of amfid patch so it doesn't hang on malformed requests (e.g. SysSecInfo) Known Bug: Apps will take longer to launch the first time they're launched after rejailbreaking due to a workaround for another bug w/ unsandboxing not working on first launch
Beta 8-2	26 January, 2018	Fixes issues with WebKit (Safari/Chrome), receiving calls, and downloading App Store apps by not working around the sandbox issue in those processes Known Bug: Apps will take longer to launch the first time they're launched after rejailbreaking due to a workaround for another bug w/ unsandboxing not working on first launch
Beta 9	27 January, 2018	Sandbox is now working on the first launch for apps and daemons (thanks stek29) Remove 0.5 second delay when launching apps or daemons that was present since beta 1 (coolstar) Check if a new beta is available when electra is launched Double-launch workaround has been removed since it's no longer needed, fixing all bugs introduced on beta 8 Remove AnemoneFonts.dylib as it was causing problems Important Note: If you are upgrading from beta 8-2 or lower to any beta 9 or higher, you will need to reinstall all tweaks and themes
Beta 10	01 February, 2018	Fix certain codesigned binaries not working with our amfi payload (coolstar) Add darwintools, debiantools (not dpkg), shell-cmds, system-cmds and uikittools Re-sign most of the bootstrap as SHA1 to prepare for them to be pushed to a repo Code cleanup (stek29 and nullpixel) Fix update checker erroneously saying there's an update in airplane mode
Beta 11	09 February, 2018	Add libjailbreak so command line tools, apps, etc. can talk to jailbreakd if needed (n_triangle_dev) Use XPC instead of UDP from libjailbreak and xpcproxy (n_triangle_dev) Use TCP instead of UDP from launchd (coolstar)
Beta 11-2	10 February, 2018	Significantly improve the reliability of jailbreakd so it can handle a large amount of process launches at once (coolstar) Make jailbreakd print directly to stderr rather than NSLog (coolstar) Fix a race condition in beta 11 that would cause jailbreakd to sometimes inject too early, and thus fail to inject (coolstar)
