+## 0.126.0
+
+### 🛑 Breaking changes 🛑
+
+- `target-allocator`: Switch to Prometheus 3.0 defaults for ScraperProtocols, requires prometheusreceiver >0.120.0 (#3872)
+
+### 💡 Enhancements 💡
+
+- `target-allocator`: Allow to configure ScraperProtocols in prometheus common config (#4000)
+- `target allocator`: set default target allocator grace period to 30 seconds (#3989)
+  The config option collectorNotReadyGracePeriod have been set to 30s by default. The target allocator now waits for 30 seconds before reallocating targets from a collector which isn't Ready.
+  Setting this value to 0 will restore previous behaviour.
+
+### 🧰 Bug fixes 🧰
+
+- `otel-allocator`: Remove overwrite of global config ScraperProtocols (#3996)
+- `target allocator`: Fix user-defined volumes in the TargetAllocator CR (#3992)
+- `collector`: add terminationGracePeriodSeconds to DaemonSet and StatefulSet specs (#4003)
