 # Changelog
 
+## 2025-08-29 - 2.6.8 - fix(tsbuild)
+Avoid process.exit in library, add confirmskiplibcheck flag, improve CLI exit handling and JSON/quiet modes, update test script
+
+- Changed package.json test script from "tsrun test/test.ts --verbose" to "tstest test/test.ts --verbose".
+- Library no longer calls process.exit from compile and compileWithErrorTracking; errors are returned or thrown so callers can decide process termination.
+- skipLibCheck behavior updated: delay/warning only happens when --confirmskiplibcheck is present; otherwise a short informational note is printed (suppressed in --quiet/--json).
+- CLI now awaits compileGlobStringObject calls and inspects a final error summary attached to argv to decide process.exit(1) when errors occurred.
+- compileGlobStringObject/exports now respect --quiet and --json modes, emit a JSON summary when --json is used, and attach the final error summary to argv so the CLI can determine exit behavior.
+
 ## 2025-08-18 - 2.6.7 - fix(tspublish)
 Bump @git.zone/tspublish dependency to ^1.10.3
