+See [spec] and [break] changes in reference implementation. Further changes:
+
+- Each algorithm variant now contains a single VHDL implementation, add_vhdltbc:
+    - for Lilliput-I variants, add_vhdltbc corresponds to the former add_vhdltbcencryptdecrypt,
+    - Lilliput-II variants do not need the decryption part of Lilliput-TBC, therefore add_vhdltbc corresponds to the former add_vdhltbcencrypt.
+
+- For Lilliput-I, the inverted multiplications have been updated to match changes to the encryption process:
+    - lane 0: Id       => inv(M)
+    - lane 1: inv(M)   => inv(M)^2
+    - lane 2: inv(M)^2 => inv(M)^3
+    - lane 3: inv(M)^3 => inv(M)^4
+    - lane 4: inv(M_R)   (unchanged)
+    - lane 5: inv(M_R)^2 (unchanged)
+    - lane 6: inv(M_R)^3 (unchanged)
+  (inv_multiplication.vhd)
+
+- Merge Sbox in one file.
+  (sbox.vhd, inner_sbox_a.vhd, inner_sbox_b, vhd,inner_sbox_c.vhd)
+
+- Create registers in file roundexe_lilliput.vhd.
+  (state_key_register.vhd, state_register.vhd, roundexe_lilliput)
+
+- Reduction of the number of signals.
+  (chiffrement.vhd)
+
+- Add self-checking testbench.
+  (top_tb.vhd)
+
+- Pipeline RoundTweakey extraction and round function.
+  (roundexe_lilliput.vhd, machine_etat_chiffrement.vhd)
+
+- Isolate input and output from critical path.
