cti-stix-elevator 3.0.0 is released

Hi everyone-

                        

We just published cti-stix-elevator version 3.0.0 on PyPi [1]. The source code is available at [2]. read-the-docs documentation is available at [3].

We would like to thank users for their patience waiting for this often promised release!

 

This is a major release.  The changes are:

 

The elevator and stepper are compliant with STIX 2.1 CS01

Python 2.7 and 3.4 are no longer supported

* Other changes:

    - Handle STIX 1.x (CybOX 2.1) custom cyber objects

    - Handle SCOs: x509-certificate, autonomous-system, software

    - Handle File extensions: raster-image-ext, pdf-ext

    - Correct deterministic id generation algorithm

    - Handle observable characteristics in infrastructure

    - Handle parameter observables in COA

    - *_types property is now optional in 2.1

    - Handle some STIX 1.x object references

    - Improved handling of STIX 1.x RelatedObjects

    - Handle aliases for threat actors better

    - Threat_actor goal set correctly

    - Handle socket address

    - Handle more headers in email-message

    - Improved handling of composite observable conversion

    - Add general elevate() method, deprecate all other methods

    - Consolidate timestamp logic

    - Use uuid4s for custom SCOs in the stepper

    - Check stepper results with stix-validator

    - In external-references, the reference property must be in URI format

* Testing changes

    - Added testing for python 3.8

    - Add new file to test main methods to interact with the elevator, use new method in test_idioms.py

* Fixes for issues:

    #174 - In test case identifying-a-threat-actor-group, a uuid is reused inappropriately

    #182 - Message 905 about package timestamp is misleading

    #186 - generate_sco_id fails to generate deterministic ID for some objects that contain special characters

    #191 - Required attributes not added when upgrading from v2.0 -> v2.1

    #193 - 'MarkableText' object has no attribute 'reference'
