-Versione 2.6g4 (2024/07/19)
+Versione 2.6h1 (20/08/2024)
+- Modif : in SimpleScarf, se assimilabile a un taglio, si considera area non pinzabile
+- Modif : in LapJoint gestito smusso nel caso Groove-Blind-RightAngles-Parallel-4
+- Modif : varie modifiche ai tagli di lama per evitare chiusura rulli pneumatici e finecorsa
+- Modif : in BatchProcessNew, se presente flag apposito in EgtCam5, si evita la generazione
+
+Versione 2.6g4 (19/07/2024)
 - Modif : in BatchProcess e BatchProcessNew si forza ricalcolo ogni volta che si è in situazione di CHECK o CHECK + GENERATE
