I'm happy to announce that latest () Tumbleweed release is a first snapshot that uses LTO by default. The snapshot survived the full openQA testing and I've been using the snapshot on both my machines. Users can look forward to smaller and faster binaries. Right now, we've been collecting statistics and we're planning to write a more detail blog post about the benefits.
The enablement wouldn't be possible without a great effort of the people who take of openSUSE:Factory. I thank them for the nice cooperation and special thanks goes to DimStar who was very patient with me.
We are still expecting a fallout of the change and we'll try to fix the potentially broken package quickly. Another unresolved topic are reproducible builds on which we are cooperating with Bernhard Wiedemann.
In order to make the announcement complete, users can expect Chromium package using LTO and a new Firefox release will newly utilize profile guided optimization (PGO).
