-* BER/CER/DER decoding, DER encoding
+* BER/CER/DER decoding, strict DER validation, DER/CER encoding

 * Basic ASN.1 data types (X.208): BOOLEAN, INTEGER, BIT STRING, OCTET
   STRING, NULL, OBJECT IDENTIFIER, ENUMERATED, all strings, UTCTime,
   GeneralizedTime, CHOICE, ANY, SEQUENCE (OF), SET (OF)
 * Size constraints checking
 * Working with sequences as high level data objects with ability to
   (un)marshall them

-* Python 2.7/3.5 compatibility
+* Aimed to be complaint with X.690-201508
+* Streaming decoding and encoding capabilities, allowing working with
+  very small memory footprint
+* Python 2.7/3.5/3.6 compatibility

 * Automatic decoding of DEFINED BY fields
 * Ability to know exact decoded objects offset and lengths in the binary
 * Automatic decoding of DEFINED BY fields
 * Ability to know exact decoded objects offset and lengths in the binary

+* Ability to allow BER-encoded data with knowing if any of specified
+  field has either DER or BER encoding (or possibly indefinite-length
+  encoding)
+* Ability to use mmap-ed files, memoryviews, iterators and CER encoder
+  dealing with the writer, giving ability to create huge ASN.1 encoded
+  files without storing all the data in the memory first
+* Ability to decode files in event generation mode, without the need to
+  keep all the data and decoded structures in the memory
+* __slots__, copy.copy() friendliness
+* Workability with pickle
+* Cython compatibility
+* Descriptive errors, with decode paths

 * Pretty printer and command-line decoder, that could conveniently
   replace utilities like either dumpasn1 or openssl asn1parse
