Prepare Release 1.4.0

[vitcpp]

Dear Community,

I new release 1.4.0 is coming. I would propose to implement the following functionality to be included into the release:

PRs are proposed to be applied:

• Add function to create spoly from an array of numbers in radians #96 (in review)
• Add "pgindent" rule for make to run pgindent #71

New functions are proposed for implementation:

• spoly(spoint[])

I would just call it 1.3.2, since the repo is already set to make the next version be 1.3.2, but that's just me. I don't really care what the version number is.

I would like to see PR #96 and PR #99 included for sure. Thank you!

Due to the adopted versioning approach (semver.org) we have to increment the minor number because we have changes in the SQL interface. The patch number is incremented when doing some changes that do not affect the interfaces. The last PR before the release will change version to 1.4.0.

Oh, yes, of course.

• spoly(spoint[])) is done
• Hash opclass for spoint #102 to be included into 1.4.0
• Remove Travis-CI tests from the pipeline #104 is proposed to be included into 1.4.0 (minor fix to disable travis-ci)

[vitcpp]

All pending 1.4.0 PRs are merged. Freeze the code for testing. The 1.4.0 tag will be assigned after some testing.

I think 1.4.0 is ok. If no objections, I'm going to set a tag and create a release artifact.

[vitcpp]

Closed as completed.
