+## CHANGELOG:
+
+### 2.3
+* Added high order function `multiSchain` for multiprocessing scripts.
+* Added two new Processing Units `PublishData` and `ReceiverData` for receiving and sending dataOut through multiple ways (tcp, ipc, inproc).
+* Added a new graphics Processing Unit `PlotterReceiver`. It is decoupled from normal processing sequence with support for data generated by multiprocessing scripts.
+* Added support for sending realtime graphic to web server.
+* XML command `schain`  is now `schain --xml`. 
+* Added a CLI tool named `schain`. 
+	* Scripts templates can be now generated with `schain generate`. 
+	* Now it is possible to search Processing Units and Operations with `schain search [module]` to get the right name and its allowed parameters.
+* Added suggestions when parameters are poorly written.
+* `Controller.start()` now runs in a different process than the process calling it.
+* Added `schainpy.utils.log` for log standarization.
+* Running script on online mode no longer ignores date and hour. Issue #1109.
+* Added support for receving voltage data directly from JARS (tcp, ipc).
+* Updated README for compatibility with MAC OS GUI installation.
+* Setup now installs numpy.
+
+### 2.2.6
+* Graphics generated by the GUI are now the same as generated by scripts. Issue #1074.
+* Added support for C extensions.
+* Function `hildebrand_sehkon` optimized with a C wrapper.
+* Numpy version updated.
+* Migration to GIT.
+
+### 2.2.5:
+* splitProfiles and combineProfiles modules were added to VoltageProc and Signal Chain GUI.
+* nProfiles of USRP data (hdf5) is the number of profiles thera are in one second.
+* jroPlotter works directly with data objects instead of dictionaries
+* script "schain" was added to Signal Chain installer
+
+### 2.2.4.1:
+* jroIO_usrp.py is update to read Sandra's data 
+* decimation in Spectra and RTI plots is always enabled.
+* time* window option added to GUI
+
+### 2.2.4:
+* jroproc_spectra_lags.py added to schainpy
+* Bug fixed in schainGUI: ProcUnit was created with the same id in some cases.
+* Bug fixed in jroHeaderIO: Header size validation.
+
+### 2.2.3.1:
+* Filtering block by time has been added.
+* Bug fixed plotting RTI, CoherenceMap and others using xmin and xmax parameters. The first day worked
+properly but the next days did not.
+
+### 2.2.3:
+* Bug fixed in GUI: Error getting(reading) Code value
+* Bug fixed in GUI: Flip option always needs channelList field
+* Bug fixed in jrodata: when one branch modified a value in "dataOut" (example: dataOut.code) this value
+was modified for every branch (because this was a reference). It was modified in data.copy()
+* Bug fixed in jroproc_voltage.profileSelector(): rangeList replaces to profileRangeList.
+
+### 2.2.2:
+* VoltageProc: ProfileSelector, Reshape, Decoder with nTxs!=1 and getblock=True was tested
+* Rawdata and testRawdata.py added to Signal Chain project
+
+### 2.2.1:
+* Bugs fixed in GUI
+* Views were improved in GUI
+* Support to MST* ISR experiments
+* Bug fixed getting noise using hyldebrant. (minimum number of points > 20%)
+* handleError added to jroplotter.py
+
+### 2.2.0:
+* GUI: use of external plotter
+* Compatible with matplotlib 1.5.0
+
+### 2.1.5:
+* serializer module added to Signal Chain
+* jroplotter.py added to Signal Chain
+
+### 2.1.4.2:
+* A new Plotter Class was added
+* Project.start() does not accept filename as a parameter anymore
+
+### 2.1.4.1:
+* Send notifications when an error different to ValueError is detected
+
+### 2.1.4:
+* Sending error notifications to signal chain administrator
+* Login to email server added
+
+### 2.1.3.3:
+* Colored Button Icons were added to GUI
+
+### 2.1.3.2:
+* GUI: user interaction enhanced
+* controller_api.py: Safe access to ControllerThead
+
+### 2.1.3.1:
+* GUI: every icon were resized
+* jroproc_voltage.py: Print a message when "Read from code" option is selected and the code is not defined inside data file
+
+### 2.1.3:
+* jroplot_heispectra.py: SpectraHeisScope was not showing the right channels
+* jroproc_voltage.py: Bug fixed selecting profiles (self.nProfiles took a wrong value),
+					 Bug fixed selecting heights by block (selecting profiles instead heights)
+* jroproc_voltage.py: New feature added: decoding data by block using FFT.
+* jroIO_heispectra.py: Bug fixed in FitsReader. Using local Fits instance instead schainpy.mode.data.jrodata.Fits.
+* jroIO_heispectra.py: Channel index list does not exist.
+
+### 2.1.2:
+* jroutils_ftp.py: Bug fixed, Any error sending file stopped the Server Thread
+				  Server thread opens and closes remote server each time file list is sent
+* jroplot_spectra.py: Noise path was not being created when noise data is saved.
+* jroIO_base.py: startTime can be greater than endTime. Example: SpreadF [18:00 *  07:00]
