Summary

Upgrades @solana/kit and the related @solana/* catalog packages from v6 to v7.

  • Bump the solana catalog entries (@solana/kit, @solana/compat, @solana/addresses, @solana/codecs-core, @solana/codecs-strings, @solana/errors, @solana/keys, @solana/promises, @solana/signers, @solana/transactions, @solana/transaction-confirmation, @solana/transaction-messages) to ^7.0.0, plus the @solana/kit deps in the examples and the root @solana/codecs-strings devDependency.
  • Planner default (behavioral change): Kit v7 lowers the default maxInstructionsPerTransaction from 64 to 16. The transaction helpers adopt this new default, so preparing a transaction whose instructions no longer fit in a single message (previously up to 64) will now produce a multi-transaction plan and throw. Callers relying on the old limit should split their instructions.
  • TransactionVersion widening: Kit v7 adds transaction version 1 to TransactionVersion, but createTransactionMessage only accepts Exclude<TransactionVersion, 1>. The transaction helpers now type their version inputs with a new SupportedTransactionVersion alias (exported from features/transactions.ts) to reflect the versions they actually support. This resolves the type errors introduced by the widened union.

Changeset: @solana/client minor bump.

Greptile Summary

This PR upgrades all @solana/* catalog packages from v6 to v7, coordinating version bumps across the workspace catalog, example apps, and root package.json, while adding a new SupportedTransactionVersion alias to accommodate Kit v7's widened TransactionVersion union.

  • Catalog & lockfile bumps: All thirteen @solana/* catalog entries move from ^6.0.1 to ^7.0.0; pnpm lockfile is regenerated consistently; example package.json files follow suit.
  • SupportedTransactionVersion type (Exclude<TransactionVersion, 1>): Exported from features/transactions.ts and imported into all four feature files (sol, spl, stake, wsol) to keep createTransactionMessage calls type-safe, since v7 adds version 1 but the helper layer does not yet handle it.
  • Changeset: Filed as minor with clear documentation of the maxInstructionsPerTransaction default change (64 → 16) and the new type export.

Confidence Score: 5/5

Safe to merge — version bumps are consistent across the workspace, the new SupportedTransactionVersion type correctly constrains the public API, and all CI checks pass.

The change is a mechanical dependency upgrade with a targeted type-level fix. Every @solana/* catalog entry is updated uniformly, the lockfile reflects the resolved v7 packages, and the SupportedTransactionVersion alias cleanly prevents callers from passing an unsupported version 1 to createTransactionMessage.

No files require special attention.

Important Files Changed

Filename Overview
packages/client/src/features/transactions.ts Introduces SupportedTransactionVersion = Exclude<TransactionVersion, 1>, replaces all TransactionVersion usages in public types and internal helpers with this alias — type-safe and well-documented.
packages/client/src/features/sol.ts Drops TransactionVersion import from @solana/kit; imports SupportedTransactionVersion from ./transactions and applies it to transactionVersion in SolTransferPrepareConfig.
packages/client/src/features/spl.ts Same mechanical swap as sol.ts; transactionVersion in SplTransferPrepareConfig now typed as SupportedTransactionVersion.
packages/client/src/features/stake.ts SupportedTransactionVersion applied to StakePrepareConfig, UnstakePrepareConfig, and WithdrawPrepareConfig; no logic changes.
packages/client/src/features/wsol.ts SupportedTransactionVersion applied to WsolWrapPrepareConfig and WsolUnwrapPrepareConfig; runtime usage of config.transactionVersion ?? 0 is unchanged from pre-PR.
pnpm-workspace.yaml All thirteen @solana/* catalog entries updated from ^6.0.1 to ^7.0.0; non-kit packages (@solana/connector, @solana/web3.js) correctly left unchanged.
.changeset/kit-v7-upgrade.md Correctly filed as minor; documents both the maxInstructionsPerTransaction default change and the new SupportedTransactionVersion export.
pnpm-lock.yaml Lockfile regenerated consistently; all @solana/* peer-dependency resolution chains updated to v7; @solana/connector@0.2.3 resolves correctly against Kit v7.

P2 The changeset bump level is patch, but this PR bumps a major dependency version (@solana/kit v6 → v7) and introduces a new exported type (SupportedTransactionVersion). Per semver convention, adding new public API surface or a significant dependency upgrade is typically a minor bump so that downstream consumers can see from the version number that something meaningfully changed.
