Yes! I'll see if I can get them done sooner rather than later...

There's no official schedule, so I can wait.  Can you get them to me in the
next week?

Technically this was always needed, but on some systems the pthread mutex
functions happen to be in the C library, so you could get away without it.
 2.1.0 also uses pthread_once, though, which is not typically in the C
library.

No, if there were critical problems we'd do another release to fix them.

I'm not completely sure.  "make install" installs a versioned library, then
symlinks libprotobuf.so to the version lib.  Installing a new version would
update the symlink.  Uninistalling the old version might delete the symlink.
 But if you uninstall the old and then re-install the new (just re-run "make
install") then everything should be good.

Re: upgrade to latest release

[Sushil Shelly]

thanks for the heads up, upgrading to 2.1.0 noticed that the c++ example now
requires -lpthread, once I compile my application it will need to know about
pthread also.

is there a set of release notes that i need to be aware of, and also are
there any patches against 2.1.0 that I may need, if so how do i find out
what they are?

will "make uninstall" take out all flavors of protocol buffer libraries (I
used make install on top of a prior install and would like to remove the
older version)

thanks

Everything Kenton says above is, of course, true. Additionally, if you
happen to be using Ubuntu, we keep up to date .debs of all the protobuf
stuff in the Drizzle PPA (since we use them pretty heavily ourselves)

A little off-topic - but do you have a cutoff date for patches to get in
to that? I've still got some Sun Studio issues I've been working on a
patch for that I'd love to be in 2.2.0...

You can just install it normally.  You may also want to recompile any apps
based on it, but this is not strictly necessary.  Although different
versions of libprotobuf.so are not binary-compatible (C++ sadly makes
compatibility too difficult to achieve), we use libtool's version numbering
to make sure that binary-incompatible versions of libprotobuf do not
overwrite each other.  So, any binaries you compiled against the old version
will continue to use the old version at runtime.
If you want to uninstall the old version, then run "make uninstall" from the
same directory where you you ran "make install" to install it.

BTW, 2.2.0 will be out in the next week or two.

upgrade to latest release

[Sushil Shelly]

Kenton,
I need to upgrade a linux installation of protocol buffers. I have 2.0.3 and
need to move up to use 2.1.0 - is there a set procedure to do this?

thanks

Sushil
