- X86-64 CPU emulation was implemented using multi platform dynarec/JIT, so finally has released officially:
* models up to P4/K8 (single core) were implemented in 2009-2011 timeframe, but were never released officially before due to multimedia instructions dependency on host x86 CPU at time (were not portable);
* more modern CPU models (up to Sandy Bridge/Bulldozer m-a) were added in 2015 for further development;
* instruction set extensions up to SSE 4.2 are implemented currently, AVX is in progress;
* virtualization extensions emulation (VMX and SVM) are in progress (partially implemented);
* some stuff (like APIC/IOAPIC, MultiProcessing, etc.) are present only in the development version currently, because are not enough stable (bug-free) in all "guest OS" cases for releases yet.
- PC/AT keyboard controller emulation was rewritten completely (as two-chip solution);
- VGA/SVGA emulation was rewritten completely (to be more exact and extensible to PCIe models);
- PCI bus/devices emulation was rewritten completely (to support progressing PCIe chipset emulation);
- all other stuff was refactored and modernized, comparing to "legacy" core-2008 (and updated from C++98 to C++11 standard). So now it is become "modern" core-2015 (final emu-core design).
- got rid 386-486 CPU models from release versions permanently (preserved only in development versions - for the testing purposes);
- same for legacy stuff like old chipsets, vga/svga cards, etc (2D/3D-accelerators, started at the end of 2014, are available only in development versions temporary and planned to be re-released at some point. All other stuff are removed permanently from the releases).
- got rid so called "newsbook" (2007) from the site permanently. Most of project development is taking place in the very tech-oriented areas now, about which quite hard to talk using anything except tech.doc-alike language. So no much reason to (modern:)talking about this stuff here, instead of thematic resources.
