@@ -33,22 +32,23 @@ Zusätzlich wird **pip** installiert, damit das **svg-polish** Modul installiert
 ## Was das Tool macht
 - Entpackt die PPTX in einen Temp‑Ordner
 - Komprimiert **JPG/JPEG, PNG, WebP, GIF** mit **CaesiumCLT** (Default `-q 90`, `-O bigger`)
-- Komprimiert **SVG** mit **svg-polish** (Default-Modus: `agressive`)
+- Komprimiert **SVG** mit **svg-polish** (Default-Modus: `balanced`)
 - Ersetzt Bilder nur, wenn die komprimierte Datei kleiner ist
 - Versucht bei PNG zusätzlich einen PNG->JPG Wechsel, wenn das Bild nach Kompression noch größer als 500 KB ist
 - Ersetzt Bilder nur, wenn sei mindestens 2% kleiner sind (verhindert *doppelte Komprimierung*)
 - Schreibt ein CSV‑Log (`.log` neben der Output‑PPTX)
 - Baut eine neue PPTX und zeigt eine Summary (Name, Größe vorher/nachher, Ersparnis %, Zeit)
 
-## Änderungen in 1.1.8
+## Änderungen in 1.1.9
-- SVG Files werden bei Vorhandensein von svg-polish anhand von 2 Profilen optimiert: balanced|agressive
+- SVG Files Default Profile: `balanced` statt `aggressive`
+- Datei-Eigenschaften der neu generierten PPTX enthält Hinweis auf Compression `compressed by PPTX Image Compressor` 
 
 ## Hinweise
 - `-t` steuert die Parallelität der Python‑Threads; intern wird `caesiumclt --threads 1` gesetzt, sobald `-t > 1`, um Oversubscription zu vermeiden. Default ist 16
 -  `-q` steuert das Qualitätslevel; intern wird `caesiumclt -q` mit diesem Wert von `0..100` benutzt, Default ist 90
 -  `--min-savings` steuert das Mindestmass an Komprimierung zur Verhinderung von doppelter Komprimierunt, Default ist 2%
 - Die Batch **verwendet bevorzugt das Embeddable Python** neben der BAT; ansonsten sucht sie echte `python.exe`/`py.exe` im PATH, **ignoriert** aber die Microsoft‑Store‑Alias‑Pfade (`WindowsApps`).
-- `--svg-profile` steuert das Vector-Optimierungsprofil `balanced|agressive`
+- `--svg-profile` steuert das Vector-Optimierungsprofil `balanced|aggressive`
