KillerPDF 1.8.90 saved 40,563 PDFs across the three main collections. Every file kept the same outcome and diagnostic detail as 1.8.80. All five measured passes matched, and the 80 damaged inputs produced no crashes or timeouts.

The corpus run took place on a busy host, so its median times are higher than the October 4 record. A same-session check on a quiet host, with 1.8.80 and 1.8.90 alternating, measured 1.8.90 2.6% faster for regression and 2.1% faster for standards and color, with identical results. 1.8.90 has no timing regression.

This measures batch opening and saving, not rendering accuracy or PDF conformance.

KillerPDF 1.8.80 saved 40,563 PDFs across the three main collections. Every file kept the same outcome and diagnostic detail as 1.8.71. Both versions received one warmup and five measured passes per collection in alternating order. The 80 damaged inputs produced no crashes or timeouts.

Compared directly with 1.8.71, median times were 0.90% longer for regression, 0.35% longer for standards and color, and 0.59% shorter for stress. All changes are below the 10% investigation threshold.

KillerPDF 1.8.71 saved 40,563 PDFs across the three main collections. This baseline was measured alongside 1.8.80 on October 4, 2026. Both versions received one warmup and five measured passes per collection in alternating order, with identical per-file outcomes and diagnostic details. The 80 damaged inputs produced no crashes or timeouts.

The paired 1.8.80 run was 0.90% slower for regression, 0.35% slower for standards and color, and 0.59% faster for stress. The full report preserves the measurements for both versions.

KillerPDF 1.8.70 saved 40,563 PDFs across the three main collections. Every file kept the same outcome and diagnostic detail as 1.8.6. The warmup and all five measured passes matched on every path, status, diagnostic, and exit code. The 80 damaged inputs produced no crashes or timeouts.

Compared with 1.8.6, median times were 2.0% longer for regression, 1.0% longer for standards and color, and 3.9% shorter for stress. All changes are below the 10% investigation threshold.

KillerPDF 1.8.6 saved 40,563 PDFs across the three main collections. Every file kept the same outcome and diagnostic detail as 1.8.4. All five measured passes matched, and the 80 damaged inputs produced no crashes or timeouts.

Compared with 1.8.4, median times were 18.2% shorter for regression, 3.4% shorter for stress, and 1.9% shorter for standards and color.

The official KillerPDF 1.8.4 release payload saved 40,563 PDFs across the three main collections. Every file kept the same outcome and diagnostic detail as 1.8.3. All five measured passes matched, and the 80 damaged inputs produced no crashes or timeouts.

Compared with the separately recorded 1.8.3 session, median times were 13.7% longer for regression, 6.4% longer for stress, and 0.5% shorter for standards and color. The 1.8.3 payload was framework-dependent, while the official 1.8.4 portable release contains a self-contained .NET 10.0.11 payload, so the difference is not isolated to application code.

This measures batch opening and saving, not rendering accuracy or PDF conformance.

KillerPDF 1.8.3 saved 40,563 PDFs across the three main collections, 1,485 more than 1.8.2. No previously successful input became a skip or save failure. All five measured passes matched on every file's outcome and diagnostic detail. The 80 damaged inputs produced no crashes or timeouts.

Compared with the recorded 1.8.2 baseline, median times were 8.5% longer for regression, 2.0% longer for stress, and essentially unchanged for standards and color. KillerPDF 1.8.3 completed more successful saves; both versions were not rerun in alternating passes during the same session.

This measures batch opening and saving, not rendering accuracy or PDF conformance. Nineteen previously skipped inputs now open but fail save-time checks; the cards include those failures.
