3.8.0 Release Candidate 1

Release Candidate for https://github.com/cytoscape/cyREST/milestone/2

Release 3.7.0

Converted the allowableValues to ints, as they were improperly un-hexed

Release 3.6.0

Remove SNAPSHOT suffice from cytoscape.api.version

3.5.1

Added BugFixes:

• Returned column JSON was leaving out cells that contained nulls, reducing length and making column JSON hard to map to SUIDS. Now returns null for null entries.
• More explicit handling of Command execution. Now execution waits for an allFinished call before returning anything.
