 ## Unreleased
 
+## v0.9.0
+
+Users willing to use `iocStats`, `ipmiComm`, `pyDevSup`, `SNMP`, `motorPIGCS2`,
+or `scaler` modules should update to this release. Users of `pmac` module
+should also update to have critical bugs fixed. Anyone who had trouble with
+versions greater than or equal to v0.7.0 building IOCs depending on Calc due to
+Sequencer linkage issues should find it easier to build with this release. Two
+new IOC images are also available: MCA and Motor PIGCS2.
+
 ### Breaking changes
 
 * base: remove CALC dependency on Sequencer. by @henriquesimoes in
