Anza unveils Agave v4.5 release plan, new features expected to activate from December 14

We Nov 11: Solana client development team Anza has published its Agave v4.5 release plan. Feature activation will be paused until after the Breakpoint conference and is expected to resume on November 19; the mainnet Beta upgrade release candidate will be finalized on November 27, mainnet validators are advised to fully adopt on December 7, and feature activation will begin on December 14.

In addition, the mainnet beta adoption process has been simplified to two steps: once 20% of stake has upgraded to v4.5, the network can move directly to the full adoption stage, which shortens the release cycle by one week. The upgrade includes: continuing rent reduction by gradually lowering the lamports-per-byte threshold; enabling direct mapping of account data so programs can read and write in place within the virtual machine; and implementing automatic program resizing, automatically adjusting the ProgramData account during upgrades to fit new code.
