 ## Latest Release - 1.1.0 (2020)
 
-TBD 
+Contributors: C. Louis, B. Cecconi
+
+Change Log for version 1.1.0:
+- Documentation: 
+  - Added readthedocs documentation, available at: https://expres.readthedocs.io/en/latest/ 
+- Configuration:
+  - `SIMU`.`NAME` and `SIMU`.`OUT` are not required anymore. `SIMU`.`NAME` is curently not used. The `SIMU`.`OUT` entry is given by the user in the `config.ini` file.
+  - Adding user-provided frequency list option
+  - New configuration option for output CDF: SRCPOS (position of the sources, in cartesian)
+  - New configuration option for output CDF: SRCVIS (for each hemisphere, sum of the visible sources)
+- Ephemeris:
+  - Adding support for use-provided WebGeoCalc ephemeris files in csv format
+  - Updated MIRIADE and WebGeoCalc ephemerides parsing methods (following undocumented webservice API changes)
+  - Modification on the User-defined ephemeris: the ephemerides given by the user can be defined to an accuracy of one second
+- Output CDF:
+  - Changing the polarization output in cdf file: `Polarization` variable indicates LH or RH polarization, `VisibleSources` provides the sum of visible sources for LH and RH polarization.
+  - Added Hemisphere_ID_Label variable in output CDF
+  - Modified the calculation of CDF output `SrcFreqMaxCMI`
+  - Modification of the CDF outputs if multiple sources
+  - Correction of an error on the CDF output time table
+- Other:
+  - Modify CDF file output version to: `...._v11.cdf`
+  - All CDF global attributes are now with type `CDF_CHAR`
+  - Modifying call to MFL (`lsh` vs. `msh`, depending on the planet)
+  - Added support for M-shell with JRM09 magnetic field model
+
