+'''New:'''\\
+Overlapping execution of fft and transpositions (MPI_ALLTOALL), steered with new parameter
+[wiki:doc/app/inipar#transpose_compute_overlap transpose_compute_overlap]. '''Attention:''' real overlapping has not been activated so far, but better cache usage already gives performance improvements.
+
+Due to fftw (instead of Temperton, r1210), tridia-solver improvements (r1212) and the better cache usage, the fft-solver speeds up for about 20% (on a 1024x1024x512 grid). (fft_xy, header, modules, parin, poisfft, tridia_solver, Makefile_check)
+
+fftw implemented for 1D-decomposition. (fft_xy)
+
+'''Changed:'''\\
+Resorting of arrays moved to separate routines {{{resort_for_...}}} (calc_spectra, poisfft, transpose)
+
+'''Bugfix:'''\\
+Bugfix concerning {{{Makefile_check}}}.  (mbuild)
