This release includes the following updates:

1. Ported KVM fixes to CVE-2020-36312, CVE-2019-19332, CVE-2018-1087, CVE-2018-10853, CVE-2017-7518, CVE-2017-2584, CVE-2017-2583, CVE-2017-1000407.
2. Fixes according to the result from CodeQL and Static Tools Logo Test.
3. Fixes according to internal security advices.
4. Use Windows High Resolution Timer API to improve guest LAPIC timer accuracy.

Rename GVM to AEHD. Starting from this release, user space program is expected to open \.\AEHD instead of \.\gvm. However, in order not to break existing program, \.\gvm is not removed from this release. Future releases may decide to remove it completely.

Note: the binary package name is changed too.

There is no difference compared with v1.8. "Android Emulator Hypervisor Driver for AMD Processors" is renamed to "Android Emulator hypervisor driver".

Fix three issues that led to emulator hang when using "adb reboot".

• Fixed a crash on Windows Insider build dev channel
• Disable "Whole Program Optimization" as it seems to break nested running on KVM.

• Fixed a race condition that might lead to host BSOD.
• For Intel processors, pinning vcpu to cpu is removed.
• Add "silent_install_safe.bat" in the package. Compared with "silent_install.bat", this script removes code for detecting and asking for administrator privilege.

The most important changes for this release:

• Allowing coexistence with Intel HAXM on Intel platform.
• Fixed a random hang when emulator is left untouched for a while or after system sleep/wakeup. This is initially reported by a Reddit user. Thanks!
• Fixed two BSOD conditions.

The most important change in this release is supporting Windows 7 drive digital signature.
There are other quality improvements as well.

Issue fixed:
Cannot coexist with VirtualBox.

Fixed an issue: android emulator process could not be killed forcefully, leaving itself spinning CPU cycles wastefully.
