# Overview

This is the v0.17.1.9 minor point release of the Monero software. This is a recommended release that contains mitigations against the ongoing memory exhaustion attack.

Some highlights of this minor release are:

- Add different limits for epee binary format for P2P and RPC
- Add more sanity checks on data size (portable_storage)
- Fix deadlock banning while updating peer lists
- Add aggressive restrictions to pre-handshake p2p buffer limit
- Add a max levin packet size by command type
- Restrict duplicate keys and unnamend sections in epee binary format
- More sanity checks in new chain block hashes
- Minor bug fixes

The complete list of changes is [available on GitHub](https://github.com/monero-project/monero/compare/v0.17.1.8...v0.17.1.9), along with [the source code](https://github.com/monero-project/monero/tree/v0.17.1.9).

A GPG-signed list of the hashes is at [https://getmonero.org/downloads/hashes.txt]({{ site.baseurl_root }}/downloads/hashes.txt) and should be treated as canonical, with the signature checked against the appropriate GPG key in the source code (in /utils/gpg_keys). To ensure that the files you download are those originally posted by the maintainers, you should both check that the hashes of your files match those on the signed list, and that the signature on the list is valid.

Two guides are available to guide you through the verification process: [Verify binaries on Windows (beginner)]({{ site.baseurl }}/resources/user-guides/verification-windows-beginner.html) and [Verify binaries on Linux, Mac, or Windows command line (advanced)]({{ site.baseurl }}/resources/user-guides/verification-allos-advanced.html).
