Notice that 3.x.x is provided **as-is** and remains **experimental**.
Floating Point operations
~~~~~~~~~~~~~~~~~~~~~~~~~
- ``in IROM``: This provides more free space in IRAM but disallows using floating operations inside ISRs.
- ``allowed in ISR``: Floats can be used in ISRs, cost is ~1KB IRAM when floats are used.
SSL Support
