Diff since v0.8.0

Closed issues:

• register v0.8.0 (#124)

Merged pull requests:

• update CI scripts to use SCIP 6.0.2 (#127) (rschwarz)

• Indicator moi (#121) (matbesancon)
• activate more QCP MOI tests (#118) (rschwarz)

• support indicator constraints
• fix segfaults when in wrong SCIP stage

Now supports OS X (#110).

Fix a regression in handling parameter types (#15, fixed in #108).

Fix incorrect handling of coefficients in quadratic constraints. We always scaled the coefficients by 0.5 but actually that should only happen to "same-variable" terms, "on the diagonal".

• add support for MathOptInterface (and JuMP 0.19)
• drop support for MathProgBase (and JuMP 0.18)
• no support for solver callbacks yet

• add more tests from MathProgBase
• add more own tests
• fix additional syntax issues with Julia 1.0

Support Julia versions 0.7 and 1.0. Upgrade to SCIP 6.

Minor bugfix release, mostly updating the CSIP dependency.

Now supports (and requires) the newest version of SCIP (5.0.0).

• Updated for Julia v0.6.
• Now supports incomplete warmstart solutions.

Update CSIP dependency to support new 4.0.0 release of SCIP.
