## Release notes
-## Version 0.8
+### Version 0.9
+
+#### Programmable properties
+
+Until now, physical properties as well as boundary and connection conditions
+were constant in time and space. In this version, they can be programmed, i.e.
+they are variables returned by functions implemented in user-defined libraries
+and submitted as dynamically loaded input libraries when Stardis starts. User
+libraries must also provide create/release functions that are invoked at
+start-up to allow users to load their data and build the internal data
+structures required by their libraries at run-time.
+
+The `stardis-input` file format has been updated to provide a set of new
+`_PROG` suffixed keywords used to define these programmed properties and
+conditions (e.g. `T_BOUNDARY_FOR_SOLID_PROG` or `H_BOUNDARY_FOR_FLUID_PROG`)
+
+#### Miscellaneous
+
+- Addition of the keyword `HF_BOUNDARY_FOR_SOLID` which allows to impose a flux
+ on a boundary with another condition. For example, a net flux can be defined
+ in addition to a convective exchange and a radiative transfer.
+- Correct the definition of a net flux as a boundary condition: it might not be
+ defined on the right side of the interface.
+- Correct the "subpath type" data of the output paths: as we attach the segment
+ type to the vertices, we need to locate the type changes along the path on
+ zero length segments, otherwise the colouring will show a misleading colour
+ gradient.
+- Replace the Mersenne Twister random number generator with Threefry: the
+ former is much less efficient at rejecting random numbers than the latter,
+ which is designed for this purpose, a feature on which parallel random number
+ generations depend heavily
