   * SDK:
     * removed the `respan` macro. This was marked as "internal use only" and was no longer used internally.
     * add `entrypoint_no_alloc!`, a more performant program entrypoint that avoids allocations, saving 20-30 CUs per unique account
+    * `cargo-build-sbf`: a workspace or package-level Cargo.toml may specify `tools-version` for overriding the default platform tools version when building on-chain programs. For example:
+```toml
+[package.metadata.solana]
+tools-version = "1.43"
+```
+or
+```toml
+[workspace.metadata.solana]
+tools-version = "1.43"
+```
+The order of precedence for the chosen tools version goes: `--tools-version` argument, package version, workspace version, and finally default version.
   * `agave-validator`: Update PoH speed check to compare against current hash rate from a Bank (#2447)
   * `solana-test-validator`: Add `--clone-feature-set` flag to mimic features from a target cluster (#2480)
   * `solana-genesis`: the `--cluster-type` parameter now clones the feature set from the target cluster (#2587)
