Deprecated functions were removed from AES
------------------------------------------

The functions `mbedtls_aes_encrypt()` and `mbedtls_aes_decrypt()` were removed.
Please use `mbedtls_internal_aes_encrypt()` and `mbedtls_internal_aes_decrypt()`
respectively.

Deprecated functions were removed from bignum
---------------------------------------------

The function `mbedtls_mpi_is_prime()` was removed. Please use
`mbedtls_mpi_is_prime_ext()` instead which additionally allows specifying the
number of Miller-Rabin rounds.

Deprecated functions were removed from cipher
---------------------------------------------

The functions `mbedtls_cipher_auth_encrypt()` and
`mbedtls_cipher_auth_decrypt()` were removed. They were superseded by
`mbedtls_cipher_auth_encrypt_ext()` and `mbedtls_cipher_auth_decrypt_ext()`
respectively which additionally support key wrapping algorithms such as
NIST_KW.
    
Deprecated functions were removed from DRBGs
--------------------------------------------

The functions `mbedtls_ctr_drbg_update()` and `mbedtls_hmac_drbg_update()`
were removed. They were superseded by `mbedtls_ctr_drbg_update_ret()` and
`mbedtls_hmac_drbg_update_ret()` respectively.

Deprecated functions were removed from ECDSA
--------------------------------------------

The functions `mbedtls_ecdsa_write_signature_det()` and
`mbedtls_ecdsa_sign_det()` were removed. They were superseded by
`mbedtls_ecdsa_write_signature()` and `mbedtls_ecdsa_sign_det_ext()`
respectively.

Deprecated functions were removed from SSL
------------------------------------------

The functions `mbedtls_ssl_conf_dh_param()` and
`mbedtls_ssl_get_max_frag_len()` were removed. Please use
`mbedtls_ssl_conf_dh_param_bin()` or `mbedtls_ssl_conf_dh_param_ctx()` and
`mbedtls_ssl_get_output_max_frag_len()` instead.


Deprecated hex-encoded primes were removed from DHM
---------------------------------------------------

The macros `MBEDTLS_DHM_RFC5114_MODP_2048_P`, `MBEDTLS_DHM_RFC5114_MODP_2048_G`,
`MBEDTLS_DHM_RFC3526_MODP_2048_P`, `MBEDTLS_DHM_RFC3526_MODP_2048_G`,
`MBEDTLS_DHM_RFC3526_MODP_3072_P`, `MBEDTLS_DHM_RFC3526_MODP_3072_G`,
`MBEDTLS_DHM_RFC3526_MODP_4096_P `and `MBEDTLS_DHM_RFC3526_MODP_4096_G` were
removed. The hex-encoded primes from RFC 5114 are deprecated because their 
derivation is not documented and therefore their usage constitutes a security 
risk. They are removed from the library without replacement.

Deprecated net.h file was removed
---------------------------------

The file `include/mbedtls/net.h` was removed because its only function was to
include `mbedtls/net_sockets.h` which now should be included directly.
