156 ----------
157
158 Version 0.9.5.112
159
160 Solver interface
161 - all solvers and integrators are now built as 'external library' DLL/SOs.
162 - new ASCENDSOLVERS environment variable gives additional search path location
163 that is checked when attempting to satisfy IMPORT statements.
164 - Fixed behaviour scons when lex/yacc not available.
165 - Many ASC_DLLSPEC qualifiers added as result of the expanded use of external
166 libraries.
167
168 Solvers
169 - CONOPT no longer needs to be present at buildtime. This was possible due
170 to permission from Arne Drud to add the 'conopt.h' file to our source code.
171 - BLAS and LINPACK are now embedded in the LSODE DLL/SO. They are not
172 part of libascend, which makes the main DLL about 1 MB smaller.
173 - Some bugs in the DOPRI5 integrator identified (full testing still not
174 completed).
175 - placeholder for a future TRON solver (work still to do on that)
176 - work underway on the IPOPT optimisation solver.
177
178 Model library
179 - Equations of state models from Krishnan.
180 - Added ASCEND port of the standard GAMS example problem.
181
182 Windows installer
183 - Added ability to download and install missing dependencies. This
184 makes getting started with ASCEND much simpler for new users.
185 - Added the user's manual (in PDF form) to the installer package.
186
187 RPM package
188 - A SUNDIALS RPM package has been submitted for inclusion in Fedora, making
189 installation of ASCEND possible with a single download on that distro.
190 - RPM divided into subpackages ascend, ascend-devel, ascend-doc.
191 - Other work on building RPMs for a range of Linux platforms using
192 the new OpenSUSE Build Service.
193
194 DEB package
195 - Fixed.
