• Remove default values for vectors because GCC can't handle it
• gcc error: checking whether a UInt is positive
• "depolarizeCells", "reinforceCandidates", "growthCandidates"

0.4.5

• Removed no longer used pre-built Swig executables for various flavors of Linux; nupic.core automatically builds Swig from embedded sources on non-Windows platforms.
• DEVOPS-141 Apply an export map to OS X, Linux, and MINGW builds of nupic.bindings shared objects.
• Refactor extension build steps into a function shared by algorithms, math, engine_internal, etc. in preparation for adding export maps.
• Work around issue in cmake 2.8.7: have external project AprUtil1StaticLib depend directly on external project Apr1StaticLib instead of its library wrapper ${APR1_STATIC_LIB_TARGET}; the latter was incorrectly interperting the dependency as another external project instead of library; but worked correctly on cmake 2.8.12.
• Completed wrapping of external static libs in add_library targets
• Represent external build of capnproto as single static library with target name ${CAPNP_STATIC_LIB_TARGET} and containing all capnproto library objects.
• No need for custom target in CREATE_CAPNPC_COMMAND function, since nupic_core_solo is the only consumer of the custom command's outputs.
• Try building nupic_core_solo intermediate static library without specifying system libraries. It's a static library and shouldn't need additional linking information.
• Removed nupic_core_solo from installed targets, since it's only an intermediate artifact and not intended to be an output product.
• issue-1034 Reorganized build to link nupic_core static library tests against the "combined" nupic_core static library, which is considered an output artifact, instead of nupic_core_solo static lib, which is only an intermediate step.
• Use library utils to correctly combine multiple static libraries into a single one.
• DEVOPS-135 Implement a hacky work-around by preloading pycapnp's exteions DLL in RTLD_GLOBAL mode, which enables resultion of capnproto references when nupic.bidnings extensions are loaded.
• Consider EPSILON while finding minPermanenceSynapse
• Refactor to make GCC stop finding false positives
• New implementation of GCC_UNINITIALIZED_VAR
• DEVOPS-135 Remove capnproto from python extensions shared libs in order to avoid conflict with capnproto methods compiled into pycapnp, possibly compiled with a different compiler/version and with different compiler/linker flags. Instead, we rely on dynamic linking of the necessary symbols from capnproto in pycapnp.
• Avoid clang error "unknown warning option '-Wno-maybe-uninitialized'"
• Store EPSILON as a static const Permanence
• Disable GCC's maybe-uninitialized warnings. Too many false positives.
• Fixes nupic.core github issue #1031: rename EXTERNAL_STATICLIB_CONFIGURE_DEFINITIONS_OPTIMIZED_STR to EXTERNAL_STATICLIB_CONFIGURE_DEFINITIONS_OPTIMIZED and turn it into a list.
• fixes floating point comparison bug
• Use group_by in TemporalMemory. No more ExcitedColumns.
• Work around another GCC maybe-uninitialized faulty error

• Stop storing segment overlap counts in a map. Now 56% faster.
• Enable errors for windows32 build in the matrix.
• Use proper float comparisons to avoid issues on 32 vs 64 bit machines.
• Perf: When using sets, use std::set::find, not std::find
• Swig needs -include cmath when building with mingw toolchain.
• Initialize swig_generated_file_compile_flags directly from COMMON_CXX_FLAGS_OPTIMIZED to avoid -Werror.
• Comment out header and binary install targets in CapnProto.cmake, since this is a duplicate of the exact same steps in srce/CMakeLists.txt, which installs other externals as well.
• Attempt to fix execution of helloregion test from Travis build by modifying .travis.yml to change directory to build/release/bin just as instructed by nupic.core/README.md.
• Added a comment about nupic.core's swig wraps relying on the macro CAPNP_LITE to have a value.
• Fix windows build of nupic.core's Swig wraps that expects CAPNP_LITE not only to be defined (capnp recommends just defining it), but to actually have a value (non-zero).
• Invoke additional nupic.core tests in Travis to make sure that things get tested and tests don't get broken again unnoticed: connections_performance_test helloregion hello_sp_tp prototest
• Refactored CommonCompilerConfig.cmake to exposed optimized and unoptimized flag sets. Fixed linux GCC build of CapnProto components by changing its configuration to use unoptimized versions of common flags. Cleaned up use of local variables in src/CMakeFiles.txt. nupic.core/CmakeLists.txt is now the only place that defines REPOSITORY_DIR for use by other modules.
