 ## Addenda
-* Note that 5.2.6 in the Spearbit audit of 2024-10-04 was resolved after the date of the audit. [PR #1113](https://github.com/balancer/balancer-v3-monorepo/pull/1113) replaces the event with explicit add/remove liquidity events, and accounts for swap fees in a separate field.

+<sup>2</sup> See [this page](https://cantina.xyz/competitions/949ad7c5-ea14-427d-b10a-54e33cef921b) for the description of the competition. The target was a pre-launch version of the codebase at [this commit](https://github.com/balancer/balancer-v3-monorepo/commit/147823666ff6556de2a01c6762ed688ab81a6a33). The follow-up post-competition review was performed on a [fork](https://github.com/cantina-forks/balancer-v3-monorepo/tree/73708b75898a62dac0535f38d1bf471ac0e538c6/) of the code after fixes (from 11/24/24, still pre-launch code). The final deployed v3 codebase contained fixes for all known issues.
