[VOTE] Releasing Hipparchus 1.7 from release candidate 1

Hipparchus development
1

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 1 can be found on the GitHub repository as tag 1.7-RC1 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-1027/

The votes will be tallied in 72 hours from now, on 2020-06-13T19:30:00Z (this is UTC time).

+1 - my unit tests which use Complex numbers have explainable differences of course.

3

My own +1 for release.

This vote has failed. Only three votes were cast (two in the thread, one using the voting widget), and only one PMC member voted. Three PMC members votes are required for releasing a version.

I will delete the artifacts.

Luc, sorry I’ve been busy with other projects the past few days. If you leave it open longer I should be able to review towards the end of this week.

6

The artifacts have been deleted on both the central maven staging repository and the Hipparchus server.

I will attempt to roll another release candidate this week.
