Solana Changelog: July 23, 2026

Solana engineering groups shipped new Agave and Firedancer variations, superior program SDK releases, and moved core protocol work ahead throughout validator shoppers, RPC 2.0, and developer tooling. The Useful resource and Inclusion Charges Solana Enchancment Doc additionally moved to accepted standing, altering how base charges are break up and burned on Solana.

Releases

This week introduced new validator consumer releases, program SDK updates, and testing tooling releases for Solana builders. Evaluation the linked launch notes for version-specific adjustments earlier than upgrading.

• Anza shipped Agave v4.3.0-alpha.2 and v4.2.0-beta.2.

• The System Program JS SDK shipped v0.13.0.
• The Memo Program JS SDK shipped v0.12.0.
• The Compute Funds Program JS SDK shipped v0.17.0.
• The Token Program JS SDK shipped v0.15.0.
• The Token 2022 Program JS SDK shipped v0.13.0.

Accepted SIMD: Useful resource and Inclusion Charges

Solana Enchancment Paperwork (SIMDs) describe proposed protocol adjustments for Solana. The Useful resource and Inclusion Charges SIMD has been accepted.

Transferring ahead, a part of the bottom charges — 2500 lamports — might be paid to the validator. The opposite half might be computed based mostly on requested compute models after which burned, implementing a protocol-level buy-and-burn technique on SOL tied to community utilization.

Validator consumer and RPC work

Agave, Firedancer, Mithril, and RPC 2.0 work continued throughout program deployment, proof-of-history effectivity, epoch boundaries, and information archiving. These adjustments deal with validator operations and infrastructure utilized by builders and community operators.

• Agave will make enhancements to this system deployment CLI, addressing one of many most important ache factors of Solana program growth: deploying a program to mainnet.
• Agave modified how proof-of-history information are grouped collectively. Proof of historical past offers validator nodes a way of time on the chain and runs as a service constantly; this alteration makes reminiscence allocation extra environment friendly by simplifying the kinds that retailer proof-of-history information, leaving more room for higher-priority duties corresponding to processing consumer transactions.
• Firedancer is making enhancements to its epoch boundary process. The epoch boundary prepares the validator set to be rewarded for its work and units up the chief node schedule for the upcoming epoch.
• Superbank will add help for archiving through Parquet recordsdata. Parquet recordsdata are frequent information storage codecs utilized in information stacks throughout organizations and are one method to archive historic information.

Program libraries, frameworks, and testing

Solana Program Library (SPL), Core BPF, program frameworks, and testing instruments additionally noticed updates this week. The work consists of subscription cancellation help, framework-level related token account helpers, and renewed Web3.js help in LiteSVM.

• The Subscription Program will enable rapid cancellation of a subscription, supporting instances the place a consumer desires to cease subsequent funds and enabling the total subscription use instances frequent in a number of SaaS companies.
• Caravel will add related token account helper CPI invocations. Related token accounts are a staple constructing block for a lot of Solana packages and permit tokens to be created and transferred between customers.
• LiteSVM will help Web3.js as soon as once more, including help for the revived @solana/web3.js framework. LiteSVM will help each Web3.js, which many legacy tasks already use, and Package, the newer internet interface to Solana.

Different developer assets

A number of groups and contributors additionally shared instruments, articles, and analysis for builders working throughout RPC, zero-knowledge proofs, Anchor releases, and proof of historical past.
