Whenever I update my TeXLive distribution by using tlmgr, I get in the output numbers such as these:

35545 -> 36463

What do they mean?

    Every tlmgr package has a unique identification number, which increases at each update, taking the first “free” number. – egreg Mar 11 '15 at 16:09

The first number is the revision installed locally before the update (or - if not present on your system), and the second number is the server revision, that is, the one currently being installed/removed (or - if not on the server).

From the output of tlmgr --help (this is from the machine-readable output section, but the information is the same):

    The revision number of the installed package, or "-" if it is not
    present locally.

    The revision number of the package on the server, or "-" if it is
    not present on the server.

The revision number sequence is not tied to the package. This number is a simple counter that is incremented on an update to any package. A new update takes the next available revision number.

  • Thanks. And is there some place where I kind look up what changes does a particular revision have? – NVaughan Mar 11 '15 at 21:34

    You can go to TeX Live SVN and enter the revision number to see the changes on that commit. – Paul Gessler Mar 11 '15 at 21:41
