Package: release.debian.org
Severity: normal
User: release.debian....@packages.debian.org
Usertags: unblock
Please unblock package: android-platform-tools-apksig
This is the next upstream release, which only fixes the password issues
as described in #857027. Upstream still doesn't have release tags,
hence the version string. I took this opportunity to include the
bash-completion to the package as well, for completeness.
Attached is the debdiff.

passwords as arrays of

UTF-8, keytool and

byte of the UTF-8

from stdin/console, and

parameter.
