+| 22.07.2021 | [**:rocket:1.5.8**](https://github.com/stnolting/neorv32/releases/tag/v1.5.8) | **New release** |
 | 22.07.2021 | 1.5.7.16 | (re-)added `mstatush` CSR (all bits are hardwired to zero: writes are ignored, reads will always return zero) - CSR address is assigned to comply with RISC-V priv. arch. spec. 1.12 |
 | 21.07.2021 | 1.5.7.15 | :bug: fixed minor bug in SLINK module (signals were missing in sensitivity lists); :warning: simplified NEOLED interrupt system (now triggered if TX FIFO fill level falls below half-full), added option to send LED strobe command ("RESET"), added FIFO status signals to status register, simplified FIFO access logic, added new top generic `IO_NEOLED_TX_FIFO` to configure NEOLED FIFO depth |
 | 18.07.2021 | 1.5.7.14 | exposed new generic `CPU_IPB_ENTRIES` to configure size of CPU instruction prefetch buffer |

 | 27.06.2021 | 1.5.7.4 | :warning: removed top's fast IRQ (FIRQ) inputs `soc_firq_i`: the FIRQs are reserved for processor-internal usage only, use the `mext_irq_i` RISC-V external interrupt signal for all external interrupt applications (via dedicated interrupt conttoller), a follow-up version of the project will introduce a customizable external interrupt controller; sourced-out FIFOs into new HDL component `neorv32_fifo.vhd` |
 | 26.06.2021 | 1.5.7.3 | edit of v1.5.7.2: RISC-V spec claims to leave destination registers of trapping load operation unchanged (do _not_ set to zero); minor CPU control logic optimizations; :sparkles: reworked bootloader to provide several new configuration and customization options |
 | 25.06.2021 | 1.5.7.2 | optimized instruction execution FSM: less hardware utilization, :lock: now _ensures_ to write ZERO to destination register if there is an exception during a load operation; made default bootloader even more HW configuration independent (GPIO, SPI and MTIME are optional; UART is optional but highly recommended); |
-| 24.06.2021 | 1.5.7.1 | sparkles: added RISC-V `Zmmul` ISA extension (via `CPU_EXTENSION_RISCV_Zmmul` generic; default = _false_): implements only the integer multiplication instructions sub-set of the `M` extension; for size-constrained setups, requires ~50% less hardware ressources than the `M` extension |

 | 23.06.2021 | [**:rocket:1.5.7**](https://github.com/stnolting/neorv32/releases/tag/v1.5.7) | **New release** _one year NEORV32!_ :tada: |
 | 21.06.2021 | 1.5.6.14 | :bug: fixed bug in debugger "park loop": `fence.i` instruction was missing before executing the DM's program buffer - this caused execution of outdated instructions from the program buffer if the **instruction cache** is implemented |
 | 21.06.2021 | 1.5.6.13 | removed `TINY_SHIFT_EN` generic; clean-up of CPU co-processor system: removed "dummy co-processor" for CSR read access, moved CPU shifter core into new co-processor; simplified default (bit-serial) shifter logic (single bit-shifts only) and multi-cycl instructions decode logic |
