## 0.5.3.0 -- 2020-03-07

* Fifth version revised C. Fixed issue with the noise reduction in the 'recAndProcess' function for the existing at the beginning file
(it is not done at all in such a case). 

## 0.6.1.0 -- 2020-03-08

* Sixth version revised A. Fixed issue with 'signsFromString' function that leads to performance penalty and to cycling. 

## 0.7.0.0 -- 2020-03-10

* Seventh version. Added new explicit dependency (mmsyn2) that earlier was implicit. Added the opportunity to define in how many times the amplitude
for the second lower note is greater than for the main one and to define the music intervals for the notes (if any). Some improvements for the documentation.

## 0.7.1.0 -- 2020-03-10

* Seventh version revised A. Fixed issue with being not compiled because of the implicit dependency being not explicitly specified.

## 0.7.1.1 -- 2020-03-10

* Seventh version revised B. Fixed issue with improper README.markdown file information.

## 0.7.2.0 -- 2020-03-11

* Seventh version revised C. Improved README.markdown file. Added exporting for all the basic functions in the DobutokO.Sound module.

## 0.7.2.1 -- 2020-03-11

* Seventh version revised D. Fixed issue with being not compiled because of the syntactic error.

## 0.8.0.0 -- 2020-03-12

* Eigth version. Added the new functions to the library that allow to produce richer sounds especially 'oberSoXSynth2FDN' one. The user can now specify a
function to be passed as an argument to it and obtain therefore own obertones formula. Added OPTIONS_GHC pragma to the module DobutokO.Sound.

## 0.8.0.1 -- 2020-03-12

* Eigth version revised A. Added the new functions to the exporting by the library.

## 0.8.1.0 -- 2020-03-12

* Eigth version revised B. Changed the sophisticated mechanism to provide real obertones in the 'oberSoXSynth2FDN' function.

## 0.8.2.0 -- 2020-03-12

* Eigth version revised C. Changed the sophisticated mechanism to provide real obertones in the 'oberSoXSynth2FDN' function. Fixed issues with some zeroes
in the functions. Some code improvements that give more stability. Documentation improvement.

## 0.9.0.0 -- 2020-03-13

* Ninth version. Changed the module structure to four modules. Added new functions in the DobutokO.Sound.Functional module to filter possible beats. Changed some
exports for DobutokO.Sound module.

## 0.9.1.0 -- 2020-03-14

* Ninth version revised A. Removed two functions from DobutokO.Sound.Functional module because of their inefficient work that leads to very long
(possibly infinitely) computation. 

## 0.10.0.0 -- 2020-03-14

* Tenth version. Added again the possibility to filter possible beats. Added new simple functions that are likely to work with previously prepared
Vector (Double, Double) that satisfies some constraints. Some documentation imrovement. Some performance optimizations.

## 0.10.1.0 -- 2020-03-14

* Tenth version revised A. Some documentation improvements. Some performance optimizations.

## 0.11.0.0 -- 2020-03-16

* Eleventh version. Added a second executable O2help that can be used to convert multiline Ukrainian text input to the needed String for the dobutokO2
program. Rewritten DobutokO.Sound.Executable module to provide more modularity. 

## 0.11.0.1 -- 2020-03-16

* Eleventh version revised A. Some documentation improvement of README.markdown file.

## 0.11.1.0 -- 2020-03-16

* Eleventh version revised B. Inserted the functionality of the second auxiliary executable O2help into the single one -- dobutokO2 with "0" first command
line option. Changed the information in the README.markdown file appropriately.

## 0.11.2.0 -- 2020-03-16

* Eleventh version revised C. Fixed issue with being not compiled because of not properly defined arguments for a function 'o2help'
in the DobutokO.Sound.Executable module.

## 0.12.0.0 -- 2020-03-17

* Twelfth version. Added a possibility to produce sound in the dobutokO2 function with only one input provided for the first command line option "7". Made
functions in the DobutokO.Sound.Executable module more modular so this grows a possibility to reuse them. Added new functions for the new functionality. Some
documentation improvements. Added as additional file "text.dat.txt" an example of the configuration for "7" first command line input. 

## 0.13.0.0 -- 2020-03-18

* Thirteenth version. Fixed issues connected with that SoX is by default for some distributions unable to work with a quantity of given files significantly more
than 1000. This led to that the program and functions could not work properly with some big amounts of data or sound data source files of some sizes. Now the
program and library work with them in a much more stable manner using temporary additional files. Some documentation, code and export improvements.

## 0.14.0.0 -- 2020-03-19

* Fourteenth version. Fixed issues connected with unneeded empty extensionless intermediate files in the current directory. Added the possibility to create
the resulting "end.wav" file and to clean the disk space from "result*" files by adding two new first command line options "8" and "80". Please, use the last
one with a special attention. See README.markdown for more information. Fixed issues with negative frequencies and durations possible in the
DobutokO.Sound.Functional functions. Added some more error messages to make debugging easier.

## 0.15.0.0 -- 2020-03-20

* Fifteenth version. Added an opportunity to work not only with octaves but also with n-th elements sets of consequential notes with the variants
of 2, 3, 4, 6, or 9 notes. Octave from such a perspective is a set of 12 notes. Some documentation improvements for the README.markdown file.

## 0.15.1.0 -- 2020-03-20

* Fifteenth version revised A. Fixed issue with the wrong mapping between the first command line arguments and the executable behaviour. Added the needed
behaviour for the "61" first command line option. Some improvement for the README.markdown file.

## 0.16.0.0 -- 2020-03-23

* Sixteenth version. Changed dependency version for directory package. Some documentation improvements for README.markdown file. Added a new module
DobutokO.Sound.IntermediateF to work with intermediate files. Changed the names of the some functions in DobutokO.Sound module and its exports.

## 0.17.0.0 -- 2020-03-25

* Seventeenth version. Added a few functions ('reverbE', 'reverb1E' etc.) to work with SoX effects to DobutokO.Sound.IntermediateF module. Added some additional
information in a dobutokO2.cabal file.

## 0.17.1.0 -- 2020-03-25

* Seventeenth version revised A. Fixed issues with being not compiled and duplicate export in 'DobutokO.Sound.IntermediateF'. Added two new functions 'soxE' and
'soxE1'. 

## 0.18.0.0 -- 2020-03-26

* Eighteenth version. Added three new funcions to the DobutokO.Sound.IntermediateF module for recording and playing of the files.
Some documentation improvements.
