### Taquito: New v.17 Releases

Hello there, it’s been quite some time since we’ve updated you here, but we’d like to share all the exciting stuff we’ve been working on in Taquito.

With the recent release of Protocol Nairobi, we bring you Taquito v17.0.0 and v17.1.0.

Protocol Nairobi released some significant changes we’ve addressed in these versions.

### Taquito v17.0.0

Protocol Nairobi came with notable significant changes:

- Some manager operations’ gas limit costs now vary depending on their signature scheme and length of the operation.
- The operation’s `sc_rollup_cement` result has been updated with a new field.

Aside from Nairobi support, we’ve also made user experience improvements in v17.0.0:

- A new feature called `EventAbstraction` provides an abstraction to Events being emitted by smart contracts (similar to `ContractAbstraction`)
- Improved custom error classes across multiple Taquito packages to have a clear hierarchy and error messages

For more details, see our release notes at: [Release Taquito v17.0.0 · ecadlabs/taquito · GitHub](https://github.com/ecadlabs/taquito/releases/tag/17.0.0)

### Taquito v17.1.0

After Protocol Nairobi changes, we took the opportunity to address several user requests and continue on user experience improvements:

- Upgraded RxJS version from v6.6.3 to v7.8.1
- Upgraded TS version to v4.2.4
- Continued improvements of custom error classes in multiple packages
- Implemented a new feature that exposes the injector in the `TezosToolkit` class, allowing users to customize injectors

For more details, see our release notes at: [Release Taquito v17.1.0 · ecadlabs/taquito · GitHub](https://github.com/ecadlabs/taquito/releases/tag/17.1.0)

💡 Note there may be breaking changes related to RxJS, TS upgrades, and error class updates, depending on how you use Taquito.
