Here are the specific to this version and the ClashX Pro series:

However, a discussion of ClashX Pro 1.97.0.4 would be incomplete without addressing the "software politics" surrounding its existence. The Clash ecosystem has always operated in a grey zone, utilized heavily by users in regions with strict internet censorship (such as China) to bypass the Great Firewall. The original developer of Clash and ClashX famously deleted their GitHub repositories, leaving a void in the community. In this context, version 1.97.0.

Technically, the core engine of ClashX Pro 1.97.0.4 is its defining characteristic. It typically utilizes the "Premium" core of the Clash project (distinct from the later "Meta" core). During the era of the 1.97.x branch, the software provided a stable implementation of the rule-based tunneling system that made Clash famous. Unlike traditional VPNs that route all traffic through a single remote server, Clash operates on a granular ruleset. In version 1.97.0.4, the software processes configuration files written in YAML, parsing thousands of rules to determine which domain or IP address should be routed through a proxy and which should be connected directly. This ability to split traffic—known as split tunneling or rule-based routing—is the software’s primary value proposition. It allows users to maintain high-speed local connections for domestic websites while seamlessly accessing international resources, a nuance that binary VPN switches cannot replicate.

Users can automate traffic steering based on specific rules—for example, sending international traffic through a proxy while keeping local traffic direct.
