CHANGELOG

GP8B V5.1 :
- GLOBAL
    - Small cleaning

- DOCUMENTS
    - Reverse changelog order (new version will be on the first line)

- SCHEMATICS
    - Better/More decoupling capacitor
    - Replacing old symbol for IC1 (CPLD)
    - Fixing the SPI 4bits only issue
    - ADDSCR_CLK was not sending the right pulses to the motherboard, this is due to
    old version without any standard in mind.

- PCB
    - J1 wasn't a male connector

- SCHEMATICS FEATURES
    - Now if the argument is not SRCVALUE, the processor will not go to the next address (1 byte in memory saved)
    on big program this improvement is not negligible.


GP8B V5.0 :
- GLOBAL
    - Switching "CERN-OHL v1.2" license to "CERN-OHLw v2 or later"

- DOCUMENTS
    - Adding the GP8B datasheet
    - Adding waveforms
    - Adding the CHANGELOG file
    - Cleaning

- SCHEMATICS
    - Small symbols changes
    - Removing old symbols
    - Adding TPS7A0518PDBZR symbol
    - Adding SN74LVC8T245DW symbol
    - Adding SN74AVC4T245D symbol
    - Set version to 5.0
    - Replacing all used 74x1Gxx symbols
        (shared power pin fix, and visual)
        (same for CD74AC238)

- PCB
    - Removing old footprints
    - Set version to 5.0
    - Adding QRCode with the Github link
    - Fixing 3D

- SCHEMATICS FEATURES
    - Replacing the old XC95288XL-10TQ144 by XC2C256-VQ100
        XC95288XL is a obsolete CPLD and is now replaced with
        a CoolRunnerII familly CPLD.
        the XC2C256-VQ100 is more hand-solder friendly too.

    - Adding the regulator TPS7A0518PDBZR for 1.8V (CPLD)
    - Adding VREF (3.3V) to the JTAG connector
    - Removing some unused pins and shrink the connector (J4) down
    - Adding a new connector for all the ALU pins (J5)
    - All capacitor for the CPLD is now 100nF
    - Adding SN74LVC8T245DW and SN74AVC4T245D to translate logic level for the CPLD

    - Renamed some connectors
    - SPI : now data come from the 8bits D-latch register (was directly controlled by the number bus)
    - Mounting holes is now on schematics

    - Renaming "OPC_CLK" to "OPCHOOSE_CLK"
    - Renaming "BCSPI_CLK" to "BCFG_SPI_CLK"

    - Renaming "Connecteur" sheet to "Connector" and "Connector.sch" to "fileConnector.sch"
    - Renaming "Registre" sheet to "Register" and "fileRegistre.sch" to "fileRegister.sch"
    - Renaming "Ram.sch" to "fileRAM.sch"
    - Renaming "SPI.sch" to "fileSPI.sch"

    - Apply the MM1 memory standard (3.3V I/O changes)


GP8B V4.0 :
    - Intial release
