 ## General

+### Environment stability
+
+Do not publish *any* SDK functions, macros, defines and includes. Define only what's needed in LT's public headers (like `Arduino.h`). Everything else is taken from `sdk_extern.h` or `WVariant.h` (TODO decide whether to keep WV public / make both private / get rid of WV and use sdk_extern only). Private headers are included by LT's .cpp units (maybe a dedicated private header that would include sdk_extern + Arduino.h).
+
+Developers wanting to use SDK functions need to include them.
+
+Explicit is better than implicit.
+
+- consider moving to C++17 (GNU)? or any newer than C++11

+Bootloader and app partitions contain CRC16 sums every 32 bytes. That results in the actual flash offsets/sizes not aligned to sector boundaries. To simplify calculations, the values shown in the table (extracted from bootloader's partition table) were aligned to 4096 bytes.
