 # Release Notes
 
+## Version 0.2.0 (2026-04-14)
+
+### Breaking changes
+
+* Adjusted to the changes introduced in [`EnergyModelsInvestments` 0.9](https://github.com/EnergyModelsX/EnergyModelsInvestments.jl/releases/tag/v0.9.0) and [`EnergyModelsBase` 0.10](https://github.com/EnergyModelsX/EnergyModelsBase.jl/releases/tag/v0.10.0):
+  * Breaking change required as early retirement is now allowed.
+  * Early retirement changes the model behavior.
+  * No other changes required.
+
 ## Version 0.1.4 (2025-12-17)
 
 * Updated the format of `descriptive_names.yaml` to [`EnergyModelsGUI` v0.6.0](https://github.com/EnergyModelsX/EnergyModelsGUI.jl/releases/tag/v0.6.0).

+# [Update your model to the latest versions](@id how_to-update)
+
+`EnergyModelsHeat` is still in a pre-release version.
+Hence, there are frequently breaking changes occuring, although we plan to keep backwards compatibility.
+This document is designed to provide users with information regarding how they have to adjust their nodal descriptions to keep compatibility to the latest changes.
+
+## [Adjustments from 0.1.2](@id how_to-update-01)
+
+### [Thermal energy storage](@id how_to-update-01-TES)
+
+!!! warning
+    The legacy constructors for calls of the type of version 0.1 will be removed in version 0.3.
+    In addition, the adjustments will not be updated in release 0.3 as potential models will be at that time most likely more than 1 year old.
+
+Starting from version 0.1.2, we introduced a discharge capacity for [`ThermalEnergyStorage`](@ref).
+As a consequence, older versions without the discharge capacity will require an adjustment to include the [`AbstractStorageParameters`](@extref EnergyModelsBase nodes-storage-phil-capacities).
+The adjustment will **not** change the behavior of the node.
+
+```julia
+# Old structure:
+ThermalEnergyStorage{CyclicRepresentative}(
+    "TES",
+    StorCapOpexFixed(FixedProfile(10), FixedProfile(0.5)),
+    StorCapOpexFixed(FixedProfile(20), FixedProfile(0.8)),
+    heat_use,
+    0.05,
+    Dict(heat_use => 1),
+    Dict(heat_use => 1),
+    ExtensionData[], # Conditional
