Extra bytes in coinbase I am working on blk file parser and there is problem with one of coinbase tx.

hex:

Let's decode it according to bitcoin developer reference specification.

0b11 0907 - testnet3 magic number 
cf44 0e00 - block size 

Block header begins:
0000 0020 - block version 
7f00 6e33 4287 2eb8 c047 5d7c 16de 070e 5d88 1958 91c2 6460 7104 0000 0000 0000 - previous block hash 
bef7 a5e4 017b 7455 9f92 e883 d556 e21f ce14 aeb7 88c9 b2e2 ffec 2c6f 4b14 a901 - merkle root hash 
0cb5 1358 - time 
cc2c 051a - bits 
e9b8 2286 - nonce 
Block header ends; 

fdaf 02 - transactions in block

And now the problem:
01 0000 00 - transaction version
00 - inputs counter
0101 - 2 unknown bytes.

I didn't found any information about this 2 unknown bytes. Any help appreciated.
I found the answer. This 'unknown bytes' described in bip144
