PR Severity: MEDIUM

Classified from changed files | 1 file | 2 lines changed

Medium (1 file)

• build/version.go - Build/version file; not under any CRITICAL, HIGH, or LOW categorized path — falls into "Other Go files not categorized above"

Analysis

This PR modifies only build/version.go (1 addition, 1 deletion), which is a version bump or build metadata change. The file is not under any specifically classified package path (lnwallet, htlcswitch, contractcourt, sweep, peer, routing, invoices, cmd, docs, etc.), so it defaults to MEDIUM per the "Other Go files not categorized above" rule.

No severity bump triggers apply:

• File count: 1 (threshold: >20)
• Lines changed: 2 (threshold: >500)
• Multiple distinct critical packages: No
