-stm32flash 0.6 was released 2021-02-12 and is available at 
-https://sourceforge.net/projects/stm32flash/files/
+Releases can be downloaded from https://sourceforge.net/projects/stm32flash/files/

-stm32flash 0.6 is a maintenance release with these highlights:
+stm32flash 0.7 was released 2022-03-26

- *  Many more devices supported G0/G4/F7/H7/L4 (various contributors)
- * GPIO sequencing reworked (Roman Savrulin)
- * Serial port handling improved (Mickael Gardet)
- * Many code improvements (Antonio Borneo)
- * Only erase needed pages if flashing from file (Tormod Volden)
-
-Please see the git log for all changes.
-
-stm32flash 0.5 was released 2016-02-11 and added:
-
- * support for multiple bank sizes
- * improved serial port support on Windows
- * improved erase functionality
- * improved hex parser
- * many new devices and device info corrections
-
-Thanks to Antonio Borneo and many other contributors (see git log and AUTHORS file)
-
-The 0.4 version is the work of Antonio Borneo and includes support for programming over I2C. See the included I2C.txt for more information. The code has been refactored to make it easier to add other transports.

    -a bus_address  Bus address (e.g. for I2C port)

    -m mode     Serial port mode (default 8e1)

    -c      Resume the connection (don't send initial INIT)
            *Baud rate must be kept the same as the first init*
            This is useful if the reset fails
+   -R      Reset device at exit.
    -i GPIO_string  GPIO sequence to enter/exit bootloader mode
            GPIO_string=[entry_seq][:[exit_seq]]
-           sequence=[-]n[,sequence]
-   -R      Reset device at exit.
+           sequence=[[-]signal]&|,[sequence]
+
+GPIO sequence:
+   The following signals can appear in a sequence:
+     Integer number representing GPIO pin
+     'dtr', 'rts' or 'brk' representing serial port signal
+   The sequence can use the following delimiters:
+     ',' adds 100 ms delay between signals
+     '&' adds no delay between signals
+   The following modifiers can be prepended to a signal:
+     '-' reset signal (low) instead of setting it (high)

 Examples:
    Get device information:
-       stm32flash /dev/ttyS0
+       ./stm32flash /dev/ttyS0
      or:
-       stm32flash /dev/i2c-0
+       ./stm32flash /dev/i2c-0

    Write with verify and then start execution:
-       stm32flash -w filename -v -g 0x0 /dev/ttyS0
+       ./stm32flash -w filename -v -g 0x0 /dev/ttyS0

    Read flash to file:
-       stm32flash -r filename /dev/ttyS0
+       ./stm32flash -r filename /dev/ttyS0

    Read 100 bytes of flash from 0x1000 to stdout:
-       stm32flash -r - -S 0x1000:100 /dev/ttyS0
+       ./stm32flash -r - -S 0x1000:100 /dev/ttyS0

    Start execution:
-       stm32flash -g 0x0 /dev/ttyS0
+       ./stm32flash -g 0x0 /dev/ttyS0

    GPIO sequence:
-   - entry sequence: GPIO_3=low, GPIO_2=low, GPIO_2=high
-   - exit sequence: GPIO_3=high, GPIO_2=low, GPIO_2=high
-       stm32flash -R -i -3,-2,2:3,-2,2 /dev/ttyS0
+   - entry sequence: GPIO_3=low, GPIO_2=low, 100ms delay, GPIO_2=high
+   - exit sequence: GPIO_3=high, GPIO_2=low, 300ms delay, GPIO_2=high
+       ./stm32flash -i '-3&-2,2:3&-2,,,2' /dev/ttyS0
+   GPIO sequence adding delay after port opening:
+   - entry sequence: delay 500ms
+   - exit sequence: rts=high, dtr=low, 300ms delay, GPIO_2=high
+       ./stm32flash -R -i ',,,,,:rts&-dtr,,,2' /dev/ttyS0
