The remaining content of this post is essentially the same as for the beta notification except Ogden material is removed.

Pricing:
If you bought version 1, 2, or 3 (before 2015-11-15) then version 5.0 is a paid upgrade for $30, $70 or $100 depending on the license.
If you bought version 4 (after 2015-11-15) then version 5.0 is a free upgrade. Just enter your existing product key to activate it.

Solver:
Piezoelectric materials in static 3D
Quadratic 2D electrostatic elements
Stiffness and compliance matrix material types
Permittivity matrix material type
Bonded contact slave surfaces can include shell edges and beam/truss ends and edges
Gyroscopic loads with two rotation axes in static 3D analysis
Tension only truss elements in static 3D and Nonlinear static 3D
Frictionless support on the edges of beam and truss elements
Non-zero initial temperatures on bonded contact nodes
More accurate calculation of temperature dependent specific heat

Tools:
Automesh 2D works on any plane
Quad local refinement work with quad8 elements
Save some features to ANSYS command file
Opening a .vol file shows the surfaces as named selections

Display/interface:
Paint selection of faces with an angle tolerance to detect edges
Cutting plane slider works for geometry view to help select internal features
Internal mesh edges don't show through the surfaces as much as before
Node dot size automatically scales in proportion to the mesh
F2 key to rename renameable items in the outline tree
+/- keys for zooming
Arrow keys move the timeline slider by single time steps
Status bar shows the number of selected items
Option to swap the mouse buttons for pan and rotate
Improved support for high DPI screens
Deformed view in one click
Nonlinear thermal solver shows convergence graph
Blank element surfaces without contour plot are available in the solution

CalculiX interoperability:
Selectable working directory for CalculiX's files
Component definitions are transferred to the postprocessor
Tables are retained between solves
Laminate (composite) materials on Quad8 elements. Doesn't transfer component definitions with them.
Plastic materials: Bilinear hardening and Ramberg-Osgood
Hyperelastic materials: Mooney-Rivlin, and Neo Hooke
Temperature dependent thermal conductivity and specific heat
Thermal stress with isotropic thermal expansion coefficients
More robust with several failure modes corrected
Force loads on offset shell faces no longer include moment loads due to the offset. CCX adds them itself.

Linux:
Improved compatibility with Wine on Linux. Recognizes product keys and doesn't pop up error messages on graphs

Removed:
Relaxation factor for thermal and Navier-Stokes analysis types
