Release v1.154.0

1.154.0 - 2026-03-04

### Fixed

• Fix crash on Windows when running semgrep ci with --debug and no blocking findings. The Windows subprocess path incorrectly raised an exception for all pysemgrep exit codes (including 0), which was silently swallowed in normal mode but propagated as a fatal error when --debug was active. (ENGINE-2491)
• Changed default memory policy from "eager" to "balanced". Scan times should noticably improve; however, scans may use 5-10% additional memory. If running in a resource-constrained environment, consider setting the memory policy back to "aggressive". (engine-2055)
• When Semgrep decides which files to scan (targeting), it can take a long time (over 5 minutes) on very large repos (> 10k files). Semgrep will now parallelize this work according to the number of jobs passed (-j) (engine-2512)
• Fixed a performance issues where passing many scannign roots on the command line (e.g. semgrep scan $(git ls-files '*.py')) caused one semgrep-core subprocess to be spawned per file. Roots that are not directories are now handled directly in Python without any subprocess overhead. (gh-11404)
• Scala: Restored parse rate after mistaken bug introduced by implicit block parsing fix (lang-215)
