No, the fixlet would need to be updated accordingly. For example, the following prefetch statement and corresponding installation commands are specific to version 5.43.0-10807.
prefetch falcon-sensor-5.43.0-10807.el7.x86_64.rpm sha1:546221fb0507d3465fdce35bddeb9ec6baeb8428 size:2433836 http://bigfix.company-domain.com:52311/Uploads/CrowdStrike/falcon-sensor-5.43.0-10807.el7.x86_64.rpm sha256:1806ae82913c59b84fe2e2afbadf2b736d1dba83eb81d7c0e93a57915628ad75
That said, it would be easy to update my source fixlet to accommodate updates versions of the CrowdStrike sensor.
