```admonish danger
It is critically important to keep in mind that the **Refresh Shares
functionality does not "restore full security" to a group**. While the group
evolves and participants are removed and new participants are added, the
security of the group does not depend only on the threshold of the current
participants being honest, but also **on the threshold of all previous set of
participants being honest**! For example, if Alice, Mallory and Eve form a group
and Mallory is eventually excluded from the group and replaced with Bob, it is
not enough to trust 2 out of 3 between Alice, Bob and Eve. **You also need to
trust that Mallory won't collude with, say, Eve which could have kept her
original pre-refresh share and they could both together recompute the original
key and compromise the group.** If that's a unnaceptable risk to your use case,
you will need to migrate to a new group if that makes sense to your application.

## Unreleased

* It is now possible to identify the culprit in `frost_core::keys::dkg::part3()`
if an invalid secret share was sent by one of the participants (by calling
frost_core::Error<C>::culprit()`).
* Added frost-secp256k1-tr crate, allowing to generate Bitcoin Taproot (BIP340/BIP341)
compatible signatures.

## 2.0.0

* Updated docs
* Added missing `derive(Getters)` for `dkg::{round1, round2}`
* Added `internal` feature for `validate_num_of_signers`
* Added refresh share functionality for trusted dealer:
`frost_core::keys::refresh::{compute_refreshing_shares, refresh_share}`
* Added a `'static` bound to the `Ciphersuite` trait. This is a breaking change,
but it's likely to not require any code changes since most ciphersuite
implementations are probably just empty structs. The bound makes it possible
to use `frost_core::Error<C>` in `Box<dyn std::error::Error>`.
* Added getters to `round1::SecretPackage` and `round2::SecretPackage`.
* Added a `frost_core::verify_signature_share()` function which allows verifying
individual signature shares. This is not required for regular FROST usage but
might useful in certain situations where it is desired to verify each
individual signature share before aggregating the signature.

## 2.0.0-rc.0
