Me contesto a mi mismo por si alguien le sirve, las encontré en mi correo electronico.
Tengo la impresión que hay mas mejoras, sobre todo en la parte de IBERplus

What's new on Iber 2.5.1:

• New structure in the result files. Now the results are written directly on the Gauss points
• The Results to Raster tool has been restructured. Now the raster files are written in a more efficient and faster way
• New tool for mesh editing elevation by height
• New formula for bed sediment transport (Recking)

• Corrections on the “Given level” inlet condition-type
• Some bugs in the “Energy” as a result that do not allowed to run the simulation when it was enabled
• Some corrections in the translation
