• New command proot-distro build: a lightweight implementation of docker build that doesn't need root privileges, Linux namespaces, etc.
• Locking for specific operations to ensure data consistency, e.g. 2 instances of proot-distro install spawned at same time should not be able to install image into container with same name
• Support installing rootfs archive from URL specified as argument for proot-distro install.
• Support pulling private images when credentials provided via export PD_DOCKER_AUTH="username:password-or-token".
• Support pushing built images to registry.
• Short aliases for certain command line options
• Add --quiet option for suppressing console messages except errors.
• Backups will store a file copy instead of link2symlink link file to improve portability.
• Fixed possible os.link() call in proot-distro restore because hard links are not allowed on Android.
• Fixed possible escaping of container path in copy and sync commands.
• Fixed bug where proot-distro sync will delete destination data when source is not readable.
• Fixed issue with --get-proot-cmd where produced proot command didn't discard host environment variables and also was printed on stderr rather than stdout.
• Faked /proc/sys/kernel/overflowuid and /proc/sys/kernel/overflowgid with value 65534 - may fix glycin causing it to run without sandbox (bwrap workaround).
• Refactoring & misc improvements
