+v0.2.1
+======
+
+This hotfix release keeps the refreshed ``0.2`` runtime stack but trims
+release housekeeping that was no longer maintained.
+
+Changed
+-------
+* README and docs installation guidance now describe the maintained
+  source-install workflow more clearly and avoid contradictory legacy paths.
+* Release-facing badges and references no longer point to retired Travis and
+  AppVeyor infrastructure.
+
+Removed
+-------
+* Obsolete Travis CI and AppVeyor configuration files from the active release
+  branch.
+* Local virtual-environment clutter is now explicitly ignored in development
+  checkouts.
+
+v0.2
+====
+
+This release refreshes straditize for modern Python and scientific Python
+stacks while preserving the original stratigraphic digitization workflow.
+
+Added
+-----
+* Result review plots can now overlay the digitized output directly on top of
+  the original image for faster visual QA.
+* The result review dialog now includes explicit ``Export data`` and
+  ``Close`` actions.
+* Stacked-area sample finding now defaults to consensus interpolation instead
+  of exposing an unfinished GUI mode switch.
+
+Changed
+-------
+* The tested runtime stack has been updated to Python 3.10-3.14 with modern
+  pandas, matplotlib, scipy, xarray, psyplot and PyQt5 releases.
+* Installation and testing docs now recommend isolated environments and
+  ``pip install -e .`` / ``pytest`` workflows instead of deprecated
+  ``setup.py install`` and ``setup.py test`` commands.
+* Plot-results review now opens as a dedicated comparison window and applies
+  configured axis scaling in the exported/reviewed data.
+
+Fixed
+-----
+* Restored compatibility with pandas 2.3 and 3.0, including Excel export,
+  project save/load, nearest-index lookups and modern DataFrame APIs.
+* Fixed modern Matplotlib / psyplot-gui toolbar integration and Qt resize
+  regressions.
+* Reduced startup noise from deprecated docstring helpers and late OpenGL
+  configuration warnings.
+* Hardened headless Qt test paths, stacked-area label handling and several
+  export/sample-editing edge cases uncovered during regression testing.
+
 v0.1.3

 Patch that forces the diagram limits to be integers.

+Highlights in 0.2
+-----------------
+
+* Modernized runtime compatibility for Python 3.10-3.14, pandas 2.3-3.0 and
+  current matplotlib / psyplot-gui stacks.
+* Improved result review by overlaying digitized output on the source image
+  with exportable comparison data.
+* Better stacked-area sample inference via consensus interpolation.
+* Restored modern Excel / NetCDF export paths and several headless Qt fixes.

 Installation
 ------------
-We highly recommend to use anaconda_ and install straditize into its own
-environment::
 
-    conda create -n straditize -c conda-forge straditize
-    conda activate straditize
+We recommend installing straditize into its own isolated environment from a
+source checkout so the tested dependency stack is explicit.
 
-or install it from the source files via::
+Recommended source install with ``pixi``::
 
     git clone https://github.com/Chilipp/straditize.git
     cd straditize
-    pip install .  # or python setup.py install, but pip is recommended
+    pixi init
+    pixi add python=3.12 "numpy>=1.26" "pandas>=2.3" "matplotlib>=3.8" "scipy>=1.13" "xarray>=2024.7" "psyplot=1.5.1" "psyplot-gui=1.5.0" "pyqt=5.15" pyqtwebengine netcdf4 openpyxl scikit-image pillow
+    pixi run pip install -e .
+    pixi run straditize
+
+Alternative source install with ``mamba``/``conda``::
+
+    git clone https://github.com/Chilipp/straditize.git
+    cd straditize
+    mamba create -n straditize python=3.12 "numpy>=1.26" "pandas>=2.3" "matplotlib>=3.8" "scipy>=1.13" "xarray>=2024.7" "psyplot=1.5.1" "psyplot-gui=1.5.0" "pyqt=5.15" pyqtwebengine netcdf4 openpyxl scikit-image pillow pip
+    mamba activate straditize
+    pip install -e .
 
 It can then be started from the command line via::
 
     straditize
 
+Validated dependency stack
+--------------------------
+
+The ``0.2`` update has been verified with:
+
+* Python 3.10 to 3.14
+* NumPy >= 1.26
+* pandas 2.3 to 3.0
+* matplotlib 3.8 to 3.10
+* SciPy >= 1.13
+* xarray >= 2024.7
+* psyplot 1.5.1
+* psyplot-gui 1.5.0
+* PyQt5 5.15
+
+Older environments may still work, but the configurations above are the ones
+that were exercised during this release refresh.
+
