@ -21,6 +21,8 @@ API Changes
Some names have been further changed to make them more consistent.
Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
* Renamings of fields inside structures, not covered by the previous list:
cipher_info.key_length -> key_bitlen
* Headers are now found in the 'mbedtls' directory (previously 'polarssl').
* The following _init() functions that could return errors have
been split into an _init() that returns void and another function that
