+# Network Upgrades and Releases
+
+Tempo uses scheduled network upgrades to introduce protocol changes. Each upgrade goes through testnet activation before mainnet. This page also tracks important releases that node operators should be aware of.
+
+For detailed release notes and binaries, see the [Changelog](/changelog).
