-## [Unreleased] - 2024-05-28
+## [Unreleased]
+
+### Added
+- Possibility to navigate Artemis just with the keyboard [#50](https://github.com/AresValley/Artemis/issues/50)
+
+### Changed
+- Improved readability of labels for filter ranges for frequency, bandwidth, and ACF
+
+### Fixed
+- Added a database load check to avoid (non critical) exceptions when applying filters without having loaded a database.
+
+## [4.0.3] - 2024-06-10
+
+### Changed
+- Optimized final package size (reduced by 30% to 50%) by explicitly including necessary plugins/DLLs and excluding unnecessary ones with Nuitka [#47](https://github.com/AresValley/Artemis/issues/47)
+
+### Fixed
+- When the links/urls in the description field of a signal are clicked, they open the default browser [#46](https://github.com/AresValley/Artemis/issues/46)
+- Fixed an error occurig on Linux where configuration file path are not properly resolved during startup with the binary version of the program (they are if running from source) [#48](https://github.com/AresValley/Artemis/issues/48)
+
+## [4.0.1] - 2024-06-9
 ### Added
 - Database format has been changed from .csv to a proper relational DB (sqlite) which is much easier handled thanks to the native library shipped with python
 - Possibility to create an arbitrary number of new databases for storing new custom signals
@@ -11,14 +31,19 @@
 - All signal parameters (such as frequency, modulation, location, etc.) are now followed by a description
 - Databases can be exported/imported for easy sharing
 - Possibility to store and view all type of documents related to a signal entry
-- Filtration process is now much more efficient due to usage of SQL queries 
+- Filtration process is now much more efficient due to usage of SQL queries
+- D-Region Absorption Predictions (DRAP) and Aurora OVATION model are now present in the Space Weather window
 
 ### Changed
 - Updated GUI libray from PyQt5 to PySide6. Artemis 4 now relies on the QtQuick framework.
-- Undefined value for frequency and bandwidth is now deprecated.
+- SigID standard database is now hosted on GitHub (the server is much faster) along with the website parser
+- Undefined value for frequency and bandwidth is now deprecated
 - Drastically reduced the number of third party libraries
 - The signals filtering page has been simplified to be more immediate and user friendly
-- Space weather page now relies on Poseidon daemon (hosted on aresvalley.com)
+- Space weather page has been greatly improved and now relies on Poseidon daemon (hosted on aresvalley.com)
+

 **Artemis** is a software designed to assist **radio frequency (RF) signal identification and storage**. It simplifies real-time spectrum analysis by leveraging one of the most extensive and community-driven databases, containing nearly **500 recognized signals**. This comprehensive software solution allows users to collect RF signals with specific parameters such as frequency, bandwidth, modulation, etc. Users can also store spectrum waterfalls, audio samples, and all types of documents for future reference. Artemis provides a robust platform to manage a wide range of RF data with precision and ease.

+# 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.

 **Artemis** is a software designed to assist **radio frequency (RF) signal identification and storage**. It simplifies real-time spectrum analysis by leveraging one of the most extensive and community-driven databases, containing nearly **500 recognized signals**. This comprehensive software solution allows users to collect RF signals with specific parameters such as frequency, bandwidth, modulation, etc. Users can also store spectrum waterfalls, audio samples, and all types of documents for future reference. Artemis provides a robust platform to manage a wide range of RF data with precision and ease.

 ## 1. Kp Index
 The **K index** is a number (from 0 to 9) that shows how much Earth's magnetic field is disturbed. A K index of 1 means things are calm, while a K index of 5 or higher indicates a geomagnetic storm. These disturbances are measured with magnetometers that track changes in Earth's magnetic field every three hours. The K itself comes from a German word "Kennziffer" meaning "characteristic digit". To get a big picture of what's happening around the world, an official planetary **Kp index** is calculated. This is done by averaging the K indices from a special network of 13 geomagnetic observatories located around the globe at mid-latitudes.
 
-## 2. A Index
+|Index|Activity Level|High Latitudes|Low Latitudes|Possible Source|
-The **A index** represents the three-hourly equivalent amplitude of geomagnetic activity at a specific magnetometer station, derived from the station-specific K index. Due to the quasi-logarithmic nature of the K-scale in relation to magnetometer fluctuations, directly averaging a set of K indices is not really meaningful. Instead each K is converted back into a linear scale. The **Ap index** is determined by averaging the eight daily A values, providing a measure of geomagnetic activity for a specific day. Days with higher levels of geomagnetic activity correspond to higher daily Ap values.

+The **A index** represents the three-hourly equivalent amplitude of geomagnetic activity at a specific magnetometer station, derived from the station-specific K index. Due to the quasi-logarithmic nature of the K-scale in relation to magnetometer fluctuations, directly averaging a set of K indices is not really meaningful. Instead each K is converted back into a linear scale. The **Ap index** is determined by averaging the eight daily Ap values (3-hour) and using the same stations grid explained for the Kp index in the previous section. This provides a measure of geomagnetic activity for a specific day. Days with higher levels of geomagnetic activity correspond to higher daily Ap values.
