Nope, they are not. Underscores in upstream version are
illegal. Please, people, read Chapter 5 of the packaging manual
before proposing version numbering schemes, this shall save a lot of
time for all concerned. I am enclosing excerpts of chapter 5 which
5. Version numbering
The version number format is:
This is a single unsigned integer, which should usually be small.
It may be omitted, in which case zero is assumed. If it is
omitted then the <upstream-version> may not contain any colons.
This is the main part of the version. It is usually version
number of the original (`upstream') package of which the `.deb'
file has been made, if this is applicable. Usually this will be
in the same format as that specified by the upstream author(s);
however, it may need to be reformatted to fit into dpkg's format
and comparison scheme.
The <upstream-version> may contain only alphanumerics and the
characters `+' `.' `-' `:' (full stop, plus, hyphen, colon) and
should start with a digit. If there is no <debian-revision> then
hyphens are not allowed; if there is no <epoch> then colons are
This part of the version represents the version of the
modifications that were made to the package to make it a Debian
binary package. It is in the same format as the
<upstream-version> and dpkg compares it in the same way.
It is optional; if it isn't present then the <upstream-version>
may not contain a hyphen. This format represents the case where a
piece of software was written specifically to be turned into a
Debian binary package, and so there is only one `debianization'
of it and therefore no revision indication is required.
It is conventional to restart the <debian-revision> at `1' each
time the <upstream-version> is increased.
dpkg will break the <upstream-version> and <debian-revision>
apart at the last hyphen in the string. The absence of a
<debian-revision> compares earlier than the presence of one (but
note that the <debian-revision> is the least significant part of
the version number).
The <debian-revision> may contain only alphanumerics and the
characters `+' and `.' (plus and full stop).
