Method overloading removed from all classes because of incompatibilities with non-MSVC compilers on Windows
To prevent accidental use with older QisMLib, QisMLib_initialize_once fn has been replaced by QisMLib_initialize_once_ext so that the run-time will fail immediately. The application does not have to call QisMLib_initialize_once_ext. They can continue to call QisMLib_initialize_once exactly as before. QisMLib_initialize_once is now a macro that redirects to QisMLib_initialize_once_ext
Bug-fix: Loading the qismhextract64.so caused a crash because of invalid use of dynamic_cast
Internal limit on the number of active files/exploders removed. These are not only contrained by the system resources (or licenses in case of exploders)

Bug-fix: In defining the stackup, it's OK to use a layer:dttp multiple times within the same order/expression. Previously, this caused an error. It's not OK to use layer:dttp across multiple order/expressions though
New licensed API QisMClipper (qismclipper.h) for computing interaction of boundaries and paths with a set of windows/regions
Enables QisMLib system-wide logging (QISM_ARG_LOGFP)
Net_refresh_mt callbacks are sent even as nets are being computed. Previously, they originated only at the beginning of processing a tile
Enables QisMLib system-wide log (QISM_ARG_LOGFP)
Enables QisMLib system-wide logging (QISM_ARG_LOGFP)
New LSynthNotify extension to check with the client if the layer synthesis is to be terminated
Enables QisMLib system wide logging (QISM_ARG_LOGFP)
Enables QisMLib system wide logging (QISM_ARG_LOGFP)
New API QisMLog (qismlog.h) for system-wide logging in QisMLib
Some QisMLib_initialize_once options can be delivered by environment vars

API Breaking change. Compatible with QisMLib 3.9
Compatible with QisMLib v3.9 (API break)

Compatible with QisMLib v3.9 (API break)
New feature LSynthSpec::Remove_partitions to remove thread partitions or not after boolean operations
Break in the API compatibility. All apps/libs using QisMLib 3.9 and it's extensions MUST be re-built using the new header files
The temp. heade file qismlib_extras.h is no longer available. It's two 'C" functions have been incorporated into QisMFileLoadCtrl class (qismfile.h)
Bug-fix: QisMBool boolean functions returned error if set A was empty. This has been fixed. Set A can be empty
Extension to QisMExploder to explode boundaries and cell references
Bug Fix: Unloading files did not decrement the file index resulting in QisMLib reaching the max. number of files open
OASIS code is now optimized for multi-threaded use
New function QisMFileLoadCtrl_ignore_text_scale and to force text scale to 0.0 upon load in order to avoid using text extents in the computation of cell extents just like OASIS
New function QisMFileLoadCtrl_load_empty_refs to control if the empty refs are loaded. If ignore-text-scale is ON, the load-empty-refs becomes necessary for cells containing only texts since those cell's extents will become 0,0,0,0
Bug fix: Possibility of a deadlock in the trace thread if the trace is interrupted
Bug fix: Rounding error during conversion of double to int
New API to define driver related METAL/CONTACT/DIFF in the stackup
New API to enable/diable driver detection for any trace
New API function to pre-compute optimal tiling parameters for a given file/stackup/cell
New API to control when the net polygons are sent to the client - during trace (live, multiple threads) or after trace (default, single thread)
New API to define a stackup
Redesigned data processor resulting in 2x speed up
Using a faster and more precise vertex counter for improved auto-tiling
In point trace, if the seed layer is 65535, all metal layers containing the seed point are treated as seeds for tracing nets (Open point trace) potentially resulting in multiple nets
Support for a new post-fix layer synthesis expressions which is both compact and more efficient. This should be the best way to use layer synthesizer

Support for loading multiple files enables. API remains the same. Previously, QisMLib::Load_file unloaded the previously file automatically before loading a new file. Now, each call to QisMLib::Load_file creates a new QisMFile handle
New QisMExplCounter function that uses hierarchical explosion to get counts much faster then the other method

Bug-fix : Get_vector_data (qismexploder.h) was returning true even if the client interrupted execution via callback return code
New QisMLib_initialize_once arg (-qismcfg) to specify a config file other than qismlib.cfg or to not load any config at all
Bug-fix: QisMLib::Load_file crashed if QisMLib::Unload_file was used to close the previous file
Bug-fix: Undefined reference error for QisMDrawObject::Get_display_vector_data
Support for creating memory maps (qismfile.h - QisMFileMemoryMaps)
API to get exploded counts for a cell+layer (QisMFile::Get_cell_layer_exploded_vertices)
Bug-fix : Exploders were not being freed correctly leading to an error after 512 calls to QisMFile::Create_exploder
