• die Herbst 2025 Versionen
  von DIVE 3_10 (DE: deutsch) sowie D3_11 (EN: englisch) zum BETA testen
  sind da: compiliert mit dem
  brandneuen INTEL(R) IFX FORTRAN 64-bit Compiler Version
  2025.2.0. Build 20250605; mit:
• 2 neuen Modulen für Profis, Details & Infos da:
  Two new features in the DIVE framework
• sowie eine Abort-Prozedur für tiefe HELIOX TG.
  
  Mit Erscheinen dieser Herbst-Versionen
  verzichten wir auf die Produktion der ZIP-Archive für die RELEASE-Versionen:
  die jeweils aktuellen D3_10 (DE) und D3_11 (EN) sind dann
  bereits diejenigen auf der BETA Test-Seite.
  
  Und, bedingt durch ein paar weitere Parameterchen, wurde auch
  die Dateistruktur des Kompartimentfiles ("f") angepasst.
  
  Auch der output vom PDIS (= Profile Dependent Intermediate Stops)
  wurde etwas verschoenert ...
  
  Es wurden auch ein paar Fehlerchen behoben:
  so war z.B. der
  ZH-L 16 b-Koeffizient des Helium Kompartiments #5 leider FALSCH!
  Dank auch an Sandra S. und Max M. von der Firma U. !!!
  Und, auf vielfachen Wunsch einer Einzelnen: Drücke in [atm] und [fsw] beim Mnemonic "z" ...
  sowie ein klitze-kleines Tool zur Konversion von Druck-Einheiten (Mnemonic "umr")
  und, natürlich: die aktualisierten Handbüchlein für die deutsche Version (3_10, DE)
  und auch die englische Version (3_11, EN);

NEWS: 09 / 2025



• the autumn 2025 version of DIVE 3_11 for BETA testing
  compiled with the INTEL(R) IFX FORTRAN 64-bit compiler
  version 2025.2.0. Build 20250605.
  
  There are now 3 new modules for the Pro:
• the post-dive bubble-risk estimator
• a tunnel-abort procedure on pure oxygen, and
• a compression abort procedure for HELIOX dives outside the USN tables.
  
  Within the dialogue for saturation diving ("SAT" mnemonic) is now a little tool for ballparks of required gases;
  also there are 2 info blocks with values from the U.S.N. diving manual converted to SI units.
  
  As well we have corrected a couple of errors:
  for e.g.: the ZH-L 16 b-coefficient of the Helium compartment #5 was flat WRONG!
  A big Thank You to Sandra S. and Max M. from company U. !!!
  
  The N₂ and HELIUM coefficients from the TONAWANDA IIa method are now integrated.
  And a little tool for the conversion of the pressure units (mnemonic "cnvr").
  Here is the already updated manual with the new features.
  
  With the release of this autumn version we do not produce any longer the ZIP archive:
  instead, the topical released version will be the one already on the BETA site.
  
  As well the file structure for the compartment data ("f") was re-structured
  due to a couple of new parameters.
  
  Also the output from the: PDIS (= Profile Dependent Intermediate Stops)
  has been embellished a little bit ...
