# Baby Ibis (v1.0.2.0)

## Summary:

`Catapult v1.0.2.0` is a pre-announced hotfix release to patch a bug in Symbol's finalization gadget. All users should update their nodes immediately. You can see our post-mortem [here](https://hackmd.io/@syndicate/postmortem-140921).

Besides this fix, we've also merged in a few enhancements.

## Bugs Fixed:

* Fixes a bug in `FinalizationContext` around voting weight. Accounts that did not have voting keys in a current epoch (but did in the previous one) were included in the calculation of `m_weight`. Now they're correctly ignored.
* Fixes a bug that would cause nodes to crash when they ran out of voting keys.

## Changes Made:

* Adds a fork height at block `528,000 ` for correct `TotalVotingBalance` calculation.
* Adjusts `finalization threshold` from **70%** to **67%** to be inline with the BFT specification.
* Stores `preCommit` and `preVote` messages for potential relay in `voting_status.dat`.
* Transaction fees are now collected *after* a custom transaction notification has been processed by network. This enables a cosigner account with`0` balance to craft a custom transaction where the multisig pays the transaction fee.
* Added support for Apple M1 builds.
* Better logging for `preCommit` messages.
