+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
+
+    - Add TPI support for Microchip tools #1205
+
+    - Add C-strings, C characters and double to terminal write
+
+    - Provide write flash in the terminal (using a cache)

+    - Provide page erase in the terminal as pgerase
+
+    - Add support for NetBSD and OpenBSD to build.sh

+ *
+ * avr_read_byte_cached() and avr_write_byte_cached() use a cache if paged
+ * routines are available and if the device memory is EEPROM or flash,
+ * otherwise they fall back to pgm->read_byte() and pgm->write_byte(),
+ * respectively. Bytewise cached read always gets its data from the cache,
+ * possibly after reading a page from the device memory. Bytewise cached
+ * write with an address in memory range only ever modifies the cache. Any
+ * modifications are written to the device after calling avr_flush_cache() or
+ * when attempting to read or write from a location outside the address range
+ * of the device memory.
+ *
+ * avr_flush_cache() synchronises pending writes to EEPROM and flash with the
+ * device. With some programmer and part combinations, flash (and sometimes
+ * EEPROM, too) looks like a NOR memory, ie, one can only write 0 bits, not 1
+ * bits. When this is detected, either page erase is deployed (eg, with parts
+ * that have PDI/UPDI interfaces), or if that is not available, both EEPROM
+ * and flash caches are fully read in, a pgm->chip_erase() command is issued
+ * and both EEPROM and flash are written back to the device. Hence, it can
+ * take minutes to ensure that a single previously cleared bit is set and,
+ * therefore, this routine should be called sparingly.
+ *
+ * avr_chip_erase_cached() erases the chip and discards pending writes() to
+ * flash or EEPROM. It presets the flash cache to all 0xff alleviating the
+ * need to read from the device flash. However, if the programmer serves
+ * bootloaders (pgm->prog_modes & PM_SPM) then the flash cache is reset
+ * instead, necessitating flash memory be fetched from the device on first
+ * read; the reason for this is that bootloaders emulate chip erase and they
+ * won't overwrite themselves (some bootloaders, eg, optiboot ignore chip
+ * erase commands) making it truly unknowable what the flash contents on
+ * device is after a chip erase.
+ *
+ * For EEPROM avr_chip_erase_cached() concludes that it has been deleted if a
+ * previously cached EEPROM page that contained cleared bits now no longer
+ * has these clear bits on the device. Only with this evidence is the EEPROM
+ * cache preset to all 0xff otherwise the cache discards all pending writes
+ * to EEPROM and is left unchanged otherwise.
+ *
+ * The avr_page_erase_cached() function erases a page and synchronises it
+ * with the cache.
+ *
+ * Finally, avr_reset_cache() resets the cache without synchronising pending
+ * writes() to the device.

+Suffix D indicates a 64-bit double, F a 32-bit float, whilst a floating point
+number without suffix defaults to 32-bit float. Hexadecimal floating point
+notation is supported. An ambiguous trailing suffix, e.g., 0x1.8D, is read as
+no-suffix float where D is part of the mantissa; use a zero exponent 0x1.8p0D

+.Pp
+An optional U suffix makes integers unsigned. Ordinary 0x hex integers are
+always treated as unsigned. +0x or -0x hex numbers are treated as signed
+unless they have a U suffix. Unsigned integers cannot be larger than 2^64-1.
+If n is an unsigned integer then -n is also a valid unsigned integer as in C.
+Signed integers must fall into the [-2^63, 2^63-1] range or a correspondingly
+smaller range when a suffix specifies a smaller type.
+.Pp
+Ordinary 0x hex integers with n hex digits (counting leading zeros) use the
+smallest size of one, two, four and eight bytes that can accommodate any
+n-digit hex integer. If an integer suffix specifies a size explicitly the
+corresponding number of least significant bytes are written, and a warning
+shown if the number does not fit into the desired representation. Otherwise,
+unsigned integers occupy the smallest of one, two, four or eight bytes
+needed. Signed numbers are allowed to fit into the smallest signed or
+smallest unsigned representation: For example, 255 is stored as one byte as
+255U would fit in one byte, though as a signed number it would not fit into a

+If an urboot bootloader does not offer a chip erase command it will tell

+programmer emulates a chip erase, if warranted by user command line
+options, by filling the remainder of unused flash below the bootloader

+However, for vector bootloaders, even under the option -xrestore an
