[VOTE] Releasing Hipparchus 1.7 from release candidate 2

This is a VOTE in order to release version 1.7 of the Hipparchus library.
Version 1.7 is a maintenance release.

Highlights in the 1.7 release are:

  • fixed a bug in ODE events handling
  • improved a lot the Complex class so it implements the new CalculusFieldElement interface
  • added several new differentiation classes to handle simpler cases
    (univariate derivatives at orders 1 and 2 and gradients) with less overhead than the existing
    DerivativeStructure .

The release candidate 2 can be found on the GitHub repository as tag 1.7-RC2 in the release-1.7 branch.

Source and binary archives are available using the staged web site downloads page at https://hipparchus.org/staging/downloads.html .

Note that the index page at /downloads does not show the 1.7 release, as it has not been voted yet.

The release notes can be read here: https://hipparchus.org/staging/changes-report.html

Maven artifacts are available at https://oss.sonatype.org/content/repositories/orghipparchus-1028/

In order to give more time than usual to potential voters, the votes will be tallied in 120 hours from now, on 2020-06-23T12:00:00Z (this is UTC time).

My own +1.

+1 for RC-2

+1 from me

+1 for releasing RC-2

I built it, verified signatures on the maven artifacts, and used with some Orekit code. I noticed some results that used to be 0.0 are now -0.0. That seems insignificant to me since it doesn’t change the meaning.

+1 for release.

Yes, this is expected, as a result from fixing issue 75, issue 76, and issue 88.

This vote PASSED, with +1 from axelclk, glauco (using the voting widget), Hank, Otmar, Evan and myself.

I will publish the artifacts soon.
