[CANCELED] [VOTE] Releasing Hipparchus 2.0 from release candidate 1

This is a VOTE in order to release version 2.0 of the Hipparchus library.
Version 2.0 is a major release.

Highlights in the 2.0 release are:

  • addition of a sequential Gauss-Newton optimizer
  • improved relative scheduling of step handlers and events handlers in ODE
  • addition of a finish callback in step handlers
  • replacement of RealFieldElement by CalculusFieldElement interface
  • many improvements in Complex to fully implement CalculusFieldElement with correct branch cuts
  • addition of FieldComplex
  • implementation of elliptic functions and integrals (for real, complex and general fields)
  • faster simultaneous computation of sinh/cosh

The release candidate 1 can be found on the GitHub repository as tag 2.0-RC1 in the release-2.0 branch.

Source and binary archives are available using the staged web site downloads page at Downloads | Hipparchus.

Note that the index page at /downloads does not show the 2.0 release, as it has not been voted yet.

The release notes can be read here: Hipparchus Release Notes | Hipparchus.

Maven artifacts are available at Index of /repositories/orghipparchus-1031

The votes will be tallied in 120 hours for now, on 2021-07-21T22:00:00Z (this is UTC time).

+1 for RC1

This Vote is canceled.
Following issue 148, I will

  • investigate the problem
  • change the convention for integrals from elliptic modulus k to parameter m
