 There is also an option to disable the reset line and use it as an I/O. While it may seem tempting to use this feature to make available an additional I/O pin available on the ATtiny85, we strongly discourage from doing so, as it led to many issues in the past.

-Micronucleus adds a small amount of delay to the Pin Change interrupt in user applications, but  this latency is low enough to not interfere with V-USB applications. Once bootloaded, an ISP or HVSP programmer can disable the reset pin, offering an extra pin for GPIO and ADC use! After disabling the reset pin functionality, of course you will no longer be able to use ISP programmers with the chip, but that's okay because we made a neat 'upgrade' program. The Upgrade program takes a compiled bootloader hex file and packs it in to an AVR program. You upload the 'upgrade' program via an existing micronucleus installation, any other bootloader, or via ISP or HVSP programmer, and once uploaded the upgrade program runs and writes over the bootloader and then installs a trampoline over it's own interrupt vector table, then reboots, launching the new bootloader. In this way users can change their bootloader to have bugfixes or different configurations like the 'jumper' versions without needing any programming tools.
-
-tiny85 does not offer any hardware bootloading support, and does not protect the bootloader from being accidentally overwritten by a misbehaving app. We recommend great caution if using flash self programming inside an uploaded program due to the potential of bricking.

-Micronucleus is now widely installed on over 40,000 Digispark devices from Digistump - a tiny unofficial arduino device, so you can be confident that micronucleus will be well supported in the future. Micronucleus is now also the recommended bootloader for Ihsan Kehribar's wonderful LittleWire devices, and can be successfully installed on to existing LittleWire's by uploading the 'upgrade' program via the old serial bootloader, then uploading the littlewire firmware via the micronucleus command line upload tool.
+ • Please make your hardware open source. At least the schematic needs to be

+ • Your documentation should mention Micronucleus and include a link to the
