Solana will enable v1 transaction-related functions on the mainnet Epoch on September 15th at 01:20 UTC. The maximum size of a single transaction will be increased from 1232 bytes to 4096 bytes, which is approximately 3.3 times the original size. The official upgrade page indicates that the activation is expected to occur at this time, and the mainnet status will be marked as activated. The new format provides more space for zero-knowledge proofs, large multi-signatures, batch processing, and some on-chain signature schemes, reducing the need for developers to split a single operation into multiple transactions. The existing legacy and v0 transactions will continue to function, so this is not a hard fork that requires all wallets and applications to switch immediately.

The new public chain Final announced on September 15th that its first major version, Shannon, is already running on the development network. The project positions itself as an “adaptive blockchain network” and showcases a structure composed of a main chain and a transaction chain, with plans to provide core facilities such as derivatives, spot trading, and stablecoins at the protocol layer. What needs to be clarified at this point is that what has been launched is Devnet, not the mature mainnet intended for everyone. The official website states that Shannon will be open to the public “in the near future,” and the current page still provides an application access link; functions such as wallets, bridges, and documentation are also marked as upcoming.

This figure does not include oil, petroleum products, and other hydrocarbons, nor does it include oilseeds and grains. On the surface, there was little change in sales amounts, with growth even observed in the building materials and food sectors; however, when calculated at constant prices, total sales volume decreased by 0.6%. The increase in nominal amounts while the actual quantity decreased indicates that price factors supported the data for that month, and it also serves as a reminder to the market that one positive growth figure alone should not be used to conclude that demand has strengthened.

Google Cloud launched on September 15th in Singapore as Singapore Engineering Center. This is not a traditional regional sales or after-sales office. According to the company's positioning, the center will bring together professionals in AI, machine learning, data, computing, core networking, storage, and frontline support, working together with enterprises to transform basic research into deployable cloud and AI systems.

On September 15th, Google announced the opening of a batch of third-party connectors in Gemini, for, and Google Workspace.
