+ <p>
+ The linked-in driver used for ber decode and per encode
+ has been replaced with nifs. To enable the usage of nifs
+ pass the nif option to erlc or asn1rt:compile when
+ compiling. If you previously used the linked-in driver,
+ you have to recompile your ASN1 modules with the current
+ version of asn1 application as the linked-in driver
+ modules have been removed.</p>

+ A few of the heavy calculations which are done for
+ encoding and decoding operations when dealing with
+ SEQUENCE OF and DEFAULT in runtime have been moved to be
+ done in compile time instead.</p>

+ <p>
+ When compiling an ASN.1 ber module with the +nif option,
+ the module will use a new nif for ber encoding,
+ increasing performance by about 5%.</p>

+ <p>
+ Tuple funs (a two-element tuple with a module name and a
+ function) are now officially deprecated and will be
+ removed in R16. Use '<c>fun M:F/A</c>' instead. To make
+ you aware that your system uses tuple funs, the very
+ first time a tuple fun is applied, a warning will be sent
+ to the error logger.</p>
