 ## [Unreleased]
 
+## [4.1.0] - 2024-10-20
+
+### Added
+- Created a setting panel for the audio player
+- Selection of the audio output device. Closes [#4](https://github.com/AresValley/Artemis/issues/4)
+- Added the following (advanced) products to the space weather module. Closes [#53](https://github.com/AresValley/Artemis/issues/53):
+  - Sun Synoptic Analysis (SAS)
+  - GOES Solar Ultraviolet Imager (SUVI), all wavelenght (94 Å, 131 Å, 171 Å, 195 Å, 284 Å, 304 Å)
+  - GOES Thematic Map (from SUVI)
+  - Large Angle and Spectrometric Coronagraph (LASCO), both C2/C3 range for optical imaging of the Sun’s corona
+  - Helioseismic and Magnetic Imager (HMI): Magnetogram, Intensitygram, Dopplergram
+
+### Fixed
+- Fixed margins for downloader window
+
+## [4.0.5] - 2024-06-15
+
+### Added
+- Possibility to navigate Artemis just with the keyboard [#50](https://github.com/AresValley/Artemis/issues/50)
+- **Windows:** automatic updates have been implemented. When a software update is available, Artemis will download the new version and install the updates automatically 
+- Multiple sigID databases can be conserved. In the case of autoload, the latest local version will be loaded
+- Added creation date and DB version in DB manager window
+
+### Changed
+- Improved readability of labels for filter ranges for frequency, bandwidth, and ACF
+- Improved Update manager and Downloader functionalities
+- OS-dependent temporary folders are now used for database download and Artemis updates
+- The logic for searching the last sigID database has changed now the discriminant is no longer the folder name but is reported as a signature in the database itself (-1 in the editable field; see documentation)
+- Old sigID databases are not deleted anymore when a new version is downloaded. This is to avoid removing databases with user changes or additions
+
+### Fixed
+- Added a database load check to avoid (noncritical) exceptions when applying filters without having loaded a database.
+- Fixed a potential issue involving the forcible closure of the downloader window, but the downloader instance keeps running
+- With the new logic in the latest sigID database search, manually imported sigID databases are officially recognized as proper ones

+# Frequently Asked Questions
+
+### What about an automatic signal recognition feature?
+This question has been asked countless times, and for good reason: in many fields, machine learning (ML) has disrupted the way we solve problems, and when applied to the right field, you can get outstanding results. **So why not on signals?**
+
+Well, the story dates back to at least 2017 when I started discussing it with several people on the rtl-sdr blog: at first, it seemed promising, but like many things, all that glitters is not gold. Let us proceed in order: 
+
+#### ML / Deep Learning approach
+A machine learning/neural network approach would not be complex (from a technical standpoint) if there were not the problem of the dataframe completeness. To be effective, neural models need to be trained on a large number of entries. The precise number can vary and strongly depends on the nature of data used for training, but commonly, numbers can be tens of thousands of entries or even more, for example. This would not be a significant concern in the case of RF signals because the various encodings that differentiate can be created artificially using for example [Fldigi](http://www.w1hkj.com/). To make these synthetic signals more like a real one, noise and artificial distortions can be added. However, this approach allows us to have a spectrum that ranges only over civilian, non-proprietary, and non-military signals (a little bit more than 150 out of 500, in the best-case scenario). Many efforts have been made in this field and some excellent results have been reported below:

+- [O’Shea, Corgan, and Clancy](https://arxiv.org/pdf/1602.04105) - Training Size: 900000 signals, 11 modulations
+- [Stefan Scholl](https://arxiv.org/pdf/1906.04459) - Training Size: 120000 signals, 18 modulations
+- [Stefan Scholl](https://panoradio-sdr.de/automatic-identification-of-160-shortwave-rf-signals-with-deep-learning/) - Training Size: 1.2 million signals, 143 modulations tested in HF
+
+Therefore, The main point is to have a good quality data frame to train the model; this is not always an easy task for the above reasons. Subsequently, as Stefan Scholl pointed out on his blog, similar modulations (MFSK-32 vs Olivia 16/500) can significantly decrease the effectiveness of discrimination. The quality of reception can also influence the result as well:  high SNR cannot always be an ideal point since the reception can be disrupted by interference or fading.
+
+#### Classical Audio Analysis
+More classical methods, such as similarity recognition between audio samples (such as using Mel-frequency cepstral coefficients, for example), could be effective, albeit marginally, if applied to the 500 signals audio sample library from sigID wiki. With the same signal encoding, the content of the signal alone can affect the similarity index and, thus, the method's effectiveness. Listening to a signal with the same modulation but encoding different information can significantly decrease the accuracy of signal recognition.

+# Solar Synoptic Analysis
+
+Synoptic maps of the solar surface are drawn each day by SWPC forecasters, providing forecasters with a broad outline of solar surface features. These maps were started on June 2, 1972 and have been produced daily since then.
+
+!!! quote "Source"
+    The Solar Synoptic Analysis is courtesy of the Space Weather Prediction Center (SWPC) part of the National Oceanic and Atmospheric Administration (NOAA), located in Boulder, Colorado.
+
+## How to Read
+
+### Active Regions
+Active regions are localized magnetic fields on the Sun. Areas with strong or intense magnetic fields provide energy for solar flares and coronal mass ejections (CMEs), so accurate forecasting of space weather activity requires an accurate picture of these regions.. Active regions are given official numbers by SWPC, and the drawings include the probabilities of C, M, and X class flares for the next 24 hours associated with each active region, along with a proton event probability.
+
+### Coronal Holes
+Coronal holes are single polarity magnetic regions that are the source of high speed solar winds which drive magnetospheric activity. Coronal holes are the most common cause of geomagnetic storms. Coronal holes have historically been identified from He I 10830A ground-based observations. The boundaries of coronal holes are shown on the synoptic drawings as lines with hash marks on the coronal hole side of the boundary line.
+
+### Neutral Lines
+Large magnetic field structures of one magnetic polarity have a ‘neutral line’ at the boundary of the different magnetic polarities of the fields. Neutral lines are associated with flaring in active regions, and filaments/prominences are often associated with the neutral lines on a quiet sun. Neutral lines appear as dashed lines on the synoptic drawings and the forecaster indicates the polarity of the magnetic field on either side of the neutral line with + (positive) and – (negative) signs.
+
+### Plages
+Plages make up most of an Active Region, and appear bright in conjunction with the dark sunspots. Plages have strong magnetic fields but disorganized magnetic fields, unlike the highly organized fields of sunspots. In the synoptic drawings, plages are colored red. It is quite normal to have regions of plage with no sunspots, which do not receive an official number since they are not considered active regions and are unlikely to produce solar flares. Plage regions are the chief source of UV variability from the sun, however.
+
+### Filaments and Prominences
+Highly-stable regions of high density gas in the low density corona are called filaments. When these occur near the limb and can be seen protruding from the corona, often in spectacular fashion, they are called prominences. When they erupt they can be a geomagnetic storm threat, but the eruptions are usually slow and don’t often drive large storms. The filaments and prominences are drawn as outlines with hash marks.
+
+## Solar Coordinates
+- Lt: The current Carrington longitude line (north to south) at solar center disk.
+- Bt: Referred to as the B-angle. The angle measured from the current position of Earth within its tilted (inclined) orbit, compared to the Sun’s equator. It ranges between + or – 7.23 degrees.
+- Pt: Referred to as the position angle. Essentially, the current angle between Earth’s geocentric north pole and the Sun’s rotational north pole. The range is between + or – 26.31 degrees.
+- Returning Carringtons: Refers to the next 3 days of returning Carrington longitude lines to the east limb of the Sun.
+
+## Spot Group Labeling
+Spot groups are labeled with their assigned NOAA SWPC number. Underneath that number are four probability numbers (from 1 to 100 %) for C-class flares, M-class flares, X-class flares, and energetic proton events.
+
+## Coronal Hole Labeling
+Coronal holes are labeled with their assigned number. Underneath that number is a plus or minus sign representing the polarity of the coronal hole. Beside that figure is a number from 1 to 4 representing confidence of coronal hole analysis (4=good; 3=fair; 2=poor; 1=uncertain).

+## Helioseismic and Magnetic Imager
+### Magnetogram
+Magnetograms show maps of the magnetic field on the Sun’s surface. The HMI instrument uses the Zeeman effect to measure the intensity of the magnetic field component along the line of sight by making use of the circularly polarized spectral line. The color chart of the magnetic field along the line of sight is designed to visually show both high and low values. Intensities less than 24G are shades of gray. Positive values of the field are green and blue. Negative values are yellow and red. Regions with a weak field appear mainly in yellow or green. Progressively positive values range from dark green to light green (at 236 G). Negative values range from light yellow to orange (at -236G). There is a strong discontinuity in the coloration at 236G. Positive or negative sunspots and other regions with an intense field appear blue or red with dark umbrae. There are 254 colors arranged symmetrically around 0. The 127 positive values include 2 grays tending toward dark, 13 greens toward light, and 110 blues toward dark. The 127 negative values include 2 grays tending toward light, 18 yellows toward dark, and 107 reds toward dark. Nominally, each color indicates a range of about 11.81 G, and the coloration altogether spans the range between -1500 G and 1500 G
+
+### Intensitygram
+HMI samples the Fe I absorption line at 6173.3 Å at six points, assuming that the "pure" profile of the Fe I line is Gaussian and the transmission profiles are delta functions, the first and second Fourier coefficients of the Fe I line profile can be calculated, and Doppler velocity estimation can be performed. An estimate of the intensity in the continuum is obtained by "reconstructing" the solar line from the Doppler offset and the thickness and depth of the line.
+
+### Dopplergram
+HMI camera 2 takes 72 images to construct a single Doppler diagram. Six images are taken at six positions across the spectral line at 6173.3 Å. Each image is taken in two polarization states, circularly polarized to the right (RCP or Stokes I-V) and circularly polarized to the left (LCP or Stokes I+V). Assuming that the absorption line is Gaussian and the transmission profiles of the HMI filter are delta functions, Fourier coefficients are calculated and then used to estimate the magnetic field B along the line of sight.
+
+## Large Angle and Spectrometric Coronagraph

+### LASCO C1 (NOT AVAILABLE)
+A Fabry–Pérot interferometer coronagraph imaging from 1.1 to 3 solar radii, non-functional since the 24 June 1998 SOHO Mission Interruption
+
+### LASCO C2 (orange)
