+# Improvements complete or in progress since the initial release of Jolt in April 2024
+
+## Functionality improvements
+
+*Support for stdlib
+
+*Support for M-extension.
+
+*In progress: on-chain verifier (Solidity). 
+
+## Verifier cost improvements
+
+*Add support for HyperKZG commitment
+
+*Add support for Quarks/Spartan grand product argument and hybrid grand product 
+(which achieves most of the verifier benefits of Quarks without a significant hit to prover time).
+
+*In progress: change how we are batching grand products, treating them all laid side-by-side as one giant circuit. This
+will reduce proof size by up to 200KB.
+
+*In progress: reduce the number of polynomial evaluation proofs from 7-10 down to 1. 
+
+## Prover cost improvements (all in progress)
+
+*Eliminate cost of pre-computed tables of eq evaluations for each sum-check,
+as per [Dao-Thaler](https://eprint.iacr.org/2024/1210).
+
+*(Nearly) [eliminate](https://github.com/a16z/jolt/issues/347) second sum-check instance in Spartan.
+
+*Implement the sum-check prover optimization from Section 3 of Angus Gruen's [paper](https://eprint.iacr.org/2024/108).
+
+*AVX-512 speedups.
+
+*GPU integration.
