 Updates to the Nano protocol are done through major node releases, occurring approximately every 1 to 4 months, and necessary patch releases in between. As changes are made to the protocol over time, newer node versions will stop peering with older versions. Details on which versions are actively peering, supported and being developed are included below.

+description: Details of the V7.0 nano node release.
+
+# V27.0
+
+--8<-- "release-details-v27-0.md"
+
+---
+
+## Upgrade notices
+
+All nodes are encouraged to upgrade to V27.0, including exchanges.
+
+In general, exchanges, services and integrations are encouraged to join [the test network](../running-a-node/test-network.md) for performing integration testing. This network mimics the live network in work requirements but has a smaller number of nodes and a lower block count for easier setup.
+
+### Database upgrade
+
+V27 includes a one-way database upgrade that takes a few minutes to run.
+
+### gcc-12 users
+
+If your system uses gcc-12 there is a known bug in the compiler optimiser that has problems compiling c++20 code.
+
+If you get a compiler error related to -Wrestrict, it's recomended to either downgrade to gcc-11 or upgrade to gcc-13 to compile the node. See more [detail here](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105329). Debian 12 (bookworm) ships with gcc-12 by default, but has a package for gcc-11.
+
+### RPC changes
+
+V27 RPC changes are  minor and non-breaking.
+
+---
+
+## Major updates
+
+### Fair Queueing Enhancements
+Designed by Piotr Wójcik, the fair queue has been integrated into the nano node, ensuring equal processing time for each network peer. The fair queue orders requests in a fair, round-robin fashion, which is needed by several components in the node, including block, network message, bootstrap request, and vote request processing. These fair queues help ensure that higher priority transactions are seen and prioritized more consistently, even during network congestion.
+
+### Network Handling Rewrite
+Significant portions of the networking stack have been rewritten and simplified. Legacy code that handled half-duplex TCP channels has been removed and all TCP connections now operate full-duplex. Asynchronous callback-style code has been replaced with coroutines in several places simplifying code flow.
+
+### Network Flow Control Improvements
+This suite of features optimises transaction processing, guards against spam and denial-of-service attacks, and ensures equitable resource distribution.
+
+### Up to 255 votes per message
+V27 allows voting messages to contain up to 255 votes per message, an increase from the previous limit of 12. This enhancement reduces voting traffic and network congestion, improving consensus efficiency and robustness. Note that this change de-peers nodes older than V26.0.
+
+### Additional prioritization bucket
+An additional prioritization bucket for amounts between Ӿ0.000001 and Ӿ0.0003 has been added, for a total of 63. More precisely, amounts above Ӿ0.0000006 (2^79 raw) and below Ӿ0.000309 (2^88 raw) will fall in this new bucket. All existing buckets remain unchanged to minimize the impact of bucket reallocation. Many Nano faucets send amounts in this range to new users trying out nano for the first time, and many wallets use Ӿ0.000001 as the minimum amount for automatic receives. More details on buckets and bucket ranges [here](../protocol-design/spam-work-and-prioritization.md/#prioritization-details).  
+
+### Configurable Logging
+A new, highly configurable logging system allows node operators to tailor logging levels and outputs, enhancing debugging and health monitoring without excessive disk space use.
+
+### Bug fixes
+Several bugs were fixed, including race conditions, missing notifications, & dependency issues.
