+## Changes to SUNDIALS in release v2.7.0
+
+- Two new NVECTOR modules added: for _hypre_ ParVector and PETSC.
+- In vector API, added new required function, N\_VGetVectorID.
+- Upgrades to sparse solver interfaces; now support CSR matrix type with KLU solver.

+- In all packages, fixed memory leak in banded preconditioner interface.
+- Fixed some examples w.r.t. switch to new macro/function names SUNRexp etc.
+- Various minor fixes to installation-related files.
+- Corrected name N\_VCloneEmptyVectorArray to N\_VCloneVectorArrayEmpty in all documentation files.
+- Updated all packages to return integers from linear solver and preconditioner 'free' functions.
+- Removed Matlab interface from distribution as it has not been updated since 2009. We expect to update this interface soon.
+- In FKINSOL, FCVODE, and FIDA, added missing Fortran interface routines so that users can supply the sparse Jacobian routine.
+- Minor corrections and additions to all User Guides, including removal of references to specific NVECTOR names in usage skeletons.
+- Additional example programs added throughout.
+- In CVODE
+  - in FCVODE, fixed argument order bugs in FCVKLU and FCVSUPERLUMT linear solver interfaces.

+  - changed each \*\*FreeB() to type int; added return(0) to each.
+  - in interpolation routines for backward problems, added logic to bypass sensitivity interpolation if input sensitivity argument is NULL.
+- In ARKODE
+  - updated linear and mass matrix solvers so that 'free' routines return integer instead of void; updated documentation accordingly.
+  - fixed initialization of linear solver performance counters.
+  - method and embedding for Billington and TRBDF2 explicit Runge-Kutta methods were swapped.

+  - implicit predictor algorithms were updated: methods 2 and 3 were improved, a new predictor approach was added, and the default choice was modified.
+  - revised handling of integer codes for specifying built-in Butcher tables: a global numbering system is still used, but methods now have #defined names to simplify the user interface.
+  - maximum number of Butcher table stages was increased from 8 to 15 to accommodate very high-order methods, and an 8th-order adaptive ERK method was added.
+  - added support for the explicit and implicit methods in an additive Runge-Kutta method to utilize different stage times, solution and embedding coefficients, to support new SSP-ARK methods.
