-Add version-aware transaction size limits. Version 1 transactions now allow up to 4096 bytes, while legacy and v0 transactions continue to use the existing 1232-byte limit. Two new helper functions are exported from `@solana/transactions`: `getTransactionSizeLimit` for compiled `Transaction` objects, and `getTransactionMessageSizeLimit` for `TransactionMessage` objects. 
-
-The existing `TRANSACTION_SIZE_LIMIT`, `TRANSACTION_PACKET_SIZE`, and `TRANSACTION_PACKET_HEADER` constants are now deprecated in favour of `getTransactionSizeLimit` and will be removed in a future major version.

-`compileTransactionMessage` now enforces four Solana protocol limits at compile time, throwing a typed `SolanaError` instead of silently producing a transaction that would be rejected by the network:
-
-- More than 64 unique account addresses → `SOLANA_ERROR__TRANSACTION__TOO_MANY_ACCOUNT_ADDRESSES`
-- More than 12 unique signer addresses → `SOLANA_ERROR__TRANSACTION__TOO_MANY_SIGNER_ADDRESSES`
-- More than 64 instructions → `SOLANA_ERROR__TRANSACTION__TOO_MANY_INSTRUCTIONS`
-- More than 255 accounts in a single instruction → `SOLANA_ERROR__TRANSACTION__TOO_MANY_ACCOUNTS_IN_INSTRUCTION`

If the client already implements `Symbol.dispose`, the new cleanup function is chained so both run on disposal.

-The transaction planner now handles the four new transaction compilation constraint errors (`TOO_MANY_ACCOUNT_ADDRESSES`, `TOO_MANY_SIGNER_ADDRESSES`, `TOO_MANY_INSTRUCTIONS`, `TOO_MANY_ACCOUNTS_IN_INSTRUCTION`) gracefully. When adding an instruction to an existing candidate transaction would violate a constraint, the planner splits it into a new transaction — the same behaviour it already had for transactions that exceed the byte size limit. If even a fresh transaction cannot accommodate the instruction, the constraint error propagates to the caller.

 # @solana/plugin-core

+### Minor Changes
+
+- [#1480](https://github.com/anza-xyz/kit/pull/1480) [`9c4fd6e`](https://github.com/anza-xyz/kit/commit/9c4fd6e67a6f70b1386f0745cf5afe0f93c75e36) Thanks [@mcintyre94](https://github.com/mcintyre94)! - Add `withCleanup` function to `@solana/plugin-core`. Plugin authors can use it to register teardown logic (e.g. closing connections or clearing timers) on a client, making it `Disposable`. If the client already implements `Symbol.dispose`, the new cleanup function is chained so both run on disposal.

+- [#1496](https://github.com/anza-xyz/kit/pull/1496) [`7f02d23`](https://github.com/anza-xyz/kit/commit/7f02d23948cc09e3f0bc70931d845569f1cb38ad) Thanks [@mcintyre94](https://github.com/mcintyre94)! - `compileTransactionMessage` now enforces four Solana protocol limits at compile time, throwing a typed `SolanaError` instead of silently producing a transaction that would be rejected by the network:
+    - More than 64 unique account addresses → `SOLANA_ERROR__TRANSACTION__TOO_MANY_ACCOUNT_ADDRESSES`
+    - More than 12 unique signer addresses → `SOLANA_ERROR__TRANSACTION__TOO_MANY_SIGNER_ADDRESSES`
+    - More than 64 instructions → `SOLANA_ERROR__TRANSACTION__TOO_MANY_INSTRUCTIONS`
+    - More than 255 accounts in a single instruction → `SOLANA_ERROR__TRANSACTION__TOO_MANY_ACCOUNTS_IN_INSTRUCTION`
+
+    All four error codes (and their context types / human-readable messages) are exported from `@solana/errors`.

+### Minor Changes

+- [#1499](https://github.com/anza-xyz/kit/pull/1499) [`742ffca`](https://github.com/anza-xyz/kit/commit/742ffcaf5304f702334e1f0b2a14cf208ae0ee5f) Thanks [@mcintyre94](https://github.com/mcintyre94)! - Add version-aware transaction size limits. Version 1 transactions now allow up to 4096 bytes, while legacy and v0 transactions continue to use the existing 1232-byte limit. Two new helper functions are exported from `@solana/transactions`: `getTransactionSizeLimit` for compiled `Transaction` objects, and `getTransactionMessageSizeLimit` for `TransactionMessage` objects.
+
+    The existing `TRANSACTION_SIZE_LIMIT`, `TRANSACTION_PACKET_SIZE`, and `TRANSACTION_PACKET_HEADER` constants are now deprecated in favour of `getTransactionSizeLimit` and will be removed in a future major version.
