<div dir="ltr">Hi devs,<div><br></div><div>Many thanks for all the hard work - I've finally made the release candidate for 5.0, along with a new release-5-0 branch on gerrit.</div><div><br></div><div>From here, the expectation is that that branch has "no new features." We will be much more hard-nosed about that than in the past, for stability and so our limited developer time can focus on the future rather than the past. Patches for release-5.0 can only</div>
<div>* fix broken things (with a reasonable minimum of refactoring to make that possible, as applicable), or</div><div>* come from a merge from release-4-6 (which has the same policy), or</div><div>* add missing or incomplete documentation, or<br>
</div><div>* add missing tests (provided they do not compromise existing tests or production code).</div><div><br></div><div>5.0 and 5.0.x releases will be made from release-5-0 branch from both gromacs.git and regressiontests.git. There are some patches currently in gerrit that we will cherry pick to release-5-0 branch, of course. I'm still working out how to get Jenkins testing to work on the new branches. <br>
</div><div><br></div><div>I have plans in the next few weeks to work on improved form and content for some kinds of documentation (e.g. <a href="http://redmine.gromacs.org/issues/1242">http://redmine.gromacs.org/issues/1242</a>), including an install guide, user guide and developer guide that will re-organize and add to what we already have.</div>
<div><br></div><div>I'll also be running some tests that we haven't made major regressions in simulation performance, and working on automating that for the future. Perhaps some non-trivial tests for correctness can be combined in here.</div>
<div><br></div><div>There are some outstanding question marks about the correctness of some kinds of modified non-bonded interaction types in release-4-6, particularly with regard to free-energy calculations, which we hope to sort out before a final 4.6.6 release around the time of the 5.0 release.</div>
<div><br></div><div>Happy coding!</div><div><br></div><div>Mark</div></div>
