* Internals:
Changes in version 7.1:
* Major changes compared to the previous version:
- Provide a new programmer -c urclock for bootloader urprotocol
+ Urclock fully supports vector bootloaders at no extra code size
+ Uprotocol
https://github.com/stefanrueger/urboot/blob/main/urprotocol.md
allows programming much shorter bootloaders with more features:
* Exports a pgm_write_page(sram, progmem) function that the
application can call at FLASHEND-4+1 to use flash as storage
* Supports EEPROM reads/writes
* Protects itself from overwriting
* Vector bootloaders: can protect the reset vector
* Offers Chip Erase function (quicker than uploading 0xff's)
+ Urclock when compiled with libreadline supports bootloaders in
terminal mode (preventing them from WDT timeout)
+ The -c urclock programmer provides a metadata interface that
allows unused flash to be used as storage
+ avrdude -c urclock is backward compatible with avrdude -c arduino

Changes in version 7.0:
* Major changes compared to the previous version:
- Completely revamped Windows support, including MSVC
- Started to add CMake (by now, parallel with autoconf/automake)
- New-architecture devices (AVR8X mega and tiny) can access all
fuses, and memory display shows meaningful alias names
- The "safemode" feature has been removed. The major class of
programmers it has been designed for (lowlevel bitbang
programmers on parallel or serial ports) virtually doesn't exist
anymore, and the fuse combination that was covered by it do not
match the fuses of modern AVR devices anyway.
- avrdude.conf is now being looked up in the location of the
executable file first, before considering the configured default
location; this eases a "portable use" where the entire suite is
not installed into its configured default location. (Basically
only relevant for unixoid systems; on Windows, this search order
has been used for many years already.)
* New devices supported:
- ATtiny828, ATtiny87, ATtiny167, ATtiny48, ATtiny102, ATtiny104
