Rust changes (48 Anchor programs): - anchor-lang 0.32.1 → 1.0.0-rc.5 - anchor-spl 0.32.1 → 1.0.0-rc.5 - CpiContext::new() program arg: .to_account_info() → .key() (Anchor 1.0 takes Pubkey) - Context lifetime params: 4 → 2 (transfer-fee project) - Removed interface-instructions feature (transfer-hook projects) - Removed [registry] section from all Anchor.toml files TypeScript changes: - @coral-xyz/anchor → @anchor-lang/core 1.0.0-rc.5 - TypeScript bumped to ^5.3.3 where needed Transfer-hook projects (7): - Added .map_err() wrappers on spl-tlv-account-resolution calls to bridge solana-program-error 2.x → 3.x ProgramError type gap - transmute_pubkey() helper for solana-pubkey 2.x → 3.x in transfer-cost - Fixed #[instruction] attribute mismatches in transfer-switch (stricter in 1.0) - AccountInfo → UncheckedAccount in Accounts structs Compression projects (3): - Replaced mpl-bubblegum 2.1.1 and spl-account-compression 1.0.0 CPI wrappers with raw invoke()/invoke_signed() — these crates depend on Solana 2.x types and have no Solana 3.x compatible release yet - New bubblegum_types.rs in cutils with reimplemented types using borsh 1.x - Added sha3 crate for keccak256 (solana_program::keccak removed in Solana 3.x) Why: Anchor 1.0 is the current release candidate. This migration ensures all program-examples build against the latest framework. Pin to RC until stable.
…erging_sub_expression - Regenerated root Cargo.lock to resolve solana-address version conflicts - basics/rent: replaced try_to_vec() with borsh::to_vec() (borsh 1.x compat) - clippy: allow diverging_sub_expression (false positive from Anchor 1.0 #[program] macro)
- Box large InterfaceAccount fields to avoid BPF stack frame overflow (12 accounts exceeded 4096-byte limit in Anchor 1.0's try_accounts) - Upgrade spl-discriminator 0.4.1→0.5.2, spl-tlv-account-resolution 0.9.0→0.11.1, spl-transfer-hook-interface 0.9.0→2.1.0 (now compatible with Solana 3.x) - Remove transmute_pubkey() hack (no longer needed with matching Pubkey types)
