 This should create a new version by copying the docs folder and the sidebars.js file to the relevant folders, as well as adding this version to versions.json.

 The black box functions supported by ACIR are:
 
+**AES128Encrypt**: ciphers the provided plaintext using AES128 in CBC mode, padding the input using PKCS#7.
+- inputs: byte array [u8; N]
+- iv: initialization vector [u8; 16]
+- key: user key [u8; 16]
+- outputs: byte vector [u8] of length `input.len() + (16 - input.len() % 16)``
+
 **AND**: performs the bitwise AND of lhs and rhs. bit_size must be the same for both inputs.
 - lhs: (witness, bit_size)

 **EcdsaSecp256r1**: Same as EcdsaSecp256k1, but done over another curve.
 
-**FixedBaseScalarMul**: scalar multiplication with a fixed generator of the embedded curve
-- input: low, high are 2 (field , 254), representing the low and high part of the input. For Barretenberg, they must both be less than 128 bits.
-- output: x and y coordinates of $low*G+high*2^{128}*G$, where G is a fixed generator
+**MultiScalarMul**: scalar multiplication with a variable base/input point (P) of the embedded curve
+- input:
+    points (FieldElement, N) a vector of x and y coordinates of input points [x1, y1, x2, y2,...].
+    scalars (FieldElement, N) a vector of low and high limbs of input scalars [s1_low, s1_high, s2_low, s2_high, ...]. (FieldElement, N) For Barretenberg, they must both be less than 128 bits.
+- output: (FieldElement, N) a vector of x and y coordinates of output points [op1_x, op1_y, op2_x, op2_y, ...]. Points computed as $s_low*P+s_high*2^{128}*P$
 
 Because the Grumpkin scalar field is bigger than the ACIR field, we provide 2 ACIR fields representing the low and high parts of the Grumpkin scalar $a$:
 $a=low+high*2^{128},$ with $low, high < 2^{128}$
