Anchor v2 RC Is Here: 90% Smaller Programs, Fuzzing by Default
Anchor v2.0.0-rc.1 is a complete rewrite of Solana's most widely used program framework, rebuilt on Pinocchio with binaries over 90% smaller and compute costs three to six times lower than v1. The release candidate ships coverage-guided fuzzing through Crucible, plus a profiler, a step debugger, and LCOV coverage as first-class CLI subcommands.
