We're very happy to announce the official release of distcc 3.0.
The release is available at <>.
Distcc 3.0 is the first new release of distcc since the 2.18.3 release
in 2004, and incorporates approximately 548 changes since 2.18.3.

Distcc 3.0 contains a major new feature: distcc-pump mode. Previously,
distcc would do C/C++ preprocessing locally, and then send the
preprocessed output to the distributed compilation servers. But with
version 3.0, distcc is now able to distribute preprocessing too, not
just compilation. The set of files to be sent to the servers is
calculated through an incremental static analysis algorithm. As a
result distcc 3.0 can be up to three times faster than earlier
versions of distcc.

Pump mode was developed at Google by Nils Klarlund, Manos Renieris,
Fergus Henderson, and Craig Silverstein with help from Dan Kegel, Dave
Nagle, Arthur Hyun, Nick Sakharov, and others.

Distcc 3.0 also contains many other contributions and bug fixes
contributed by various people since the previous release. For
see the NEWS file <>.

Please send feedback on this release candidate to
<>, and report issues at


  Fergus Henderson (maintainer) and the distcc team at Google.
