 **Summary**: Adds solver log capture through the Python logging system, exposes `progress` and `log_fn` parameters on solve/optimize, and fixes `cluster_weight` loss during NetCDF roundtrip.
 
-### ✨ Added
+### Added
 
 - **Solver log capture**: New `CONFIG.Solving.capture_solver_log` option routes solver output (HiGHS, Gurobi, etc.) through the `flixopt.solver` Python logger at INFO level. This allows capturing solver output in any Python log handler (console, file, or both) and filtering it independently from flixopt application logs. Enabled automatically by `CONFIG.debug()`, `CONFIG.exploring()`, `CONFIG.production()`, and `CONFIG.notebook()` presets. ([#606](https://github.com/flixOpt/flixopt/pull/606))
 - **`progress` parameter**: `solve()`, `optimize()`, and `rolling_horizon()` now accept a `progress` parameter (default `True`) to control the tqdm progress bar independently of CONFIG settings.
 - **`log_fn` parameter**: `solve()` now accepts a `log_fn` parameter to persist the solver log to a file.
 
-### ♻️ Changed
+### Changed
 
 - **Presets**: `CONFIG.debug()` and `CONFIG.exploring()` now set `log_to_console=False` (solver output is routed through the Python logger instead of native console output).
 - **`CONFIG.Solving.log_to_console`** now exclusively controls the solver's native console output. It no longer affects the tqdm progress bar (use the `progress` parameter instead).
 
-### 🐛 Fixed
+### Bug Fixes
 
 - **Clustering IO**: `cluster_weight` is now preserved during NetCDF roundtrip for manually constructed clustered FlowSystems (i.e. `FlowSystem(..., clusters=..., cluster_weight=...)`). Previously, `cluster_weight` was silently dropped to `None` during `save->reload->solve`, causing incorrect objective values. Systems created via `.transform.cluster()` were not affected.
 
-### 📦 Dependencies

 - **tsam**: Updated bounds to `>= 3.1.2, < 4` (was `>= 3.0.0, < 4, != 3.1.0`). tsam 3.0.0 and 3.1.0 were yanked from PyPI. Dev pin updated from `3.0.0` to `3.1.2`.

 **Summary**: Bugfix release addressing clustering issues with multi-period systems and ExtremeConfig.
 
-### 🐛 Fixed
+### Bug Fixes
 
 - **Multi-period clustering with ExtremeConfig** - Fixed `ValueError: cannot reshape array` when clustering multi-period or multi-scenario systems with `ExtremeConfig`. The fix uses pandas `.unstack()` instead of manual reshape for robustness.
 - **Consistent cluster count validation** - Added validation to detect inconsistent cluster counts across periods/scenarios, providing clear error messages.
 
-### 💥 Breaking Changes
+### Breaking Changes
 
 - **ExtremeConfig method restriction for multi-period systems** - When using `ExtremeConfig` with multi-period or multi-scenario systems, only `method='replace'` is now allowed. Using `method='new_cluster'` or `method='append'` will raise a `ValueError`. This works around a tsam bug where these methods can produce inconsistent cluster counts across slices.

 - Restructured the modeling of the On/Off state of Flows or Components

 - Fixed the lower bound of `flow_rate` when using optional investments without OnOffParameters
 - Fixed bug that prevented divest effects from working
 - Added lower bounds of 0 to two unbounded vars (numerical improvement)
