# Changelog
This changelog follows the format defined here: https://keepachangelog.com/en/1.0.0/
## [1.10.0] - 2023-6-16
Adds superscalar in-order core, prefetchers, architectural checkpointing, examples for custom-chiptop/tapeout-chip/flat-chiptop. FireSim bumped with new local FPGA support: Xilinx VCU118 (w/XDMA), Xilinx Alveo U250/U280 (w/XDMA, in addition to previous Vitis support), RHSResearch NiteFury II (w/XDMA). FireSim now also supports Xcelium for metasims.
