Bug fixes:

#47 -nprocs removed in keyplayer kp-info command line
#48 empty result with kp-finder
#49 -seed argument removed in pyntacle generator
#50 --plot-format option removed from 1.2 onward
#51 seed argument removed in group degree API
#52 bad handling of missing output file names
#53 bad handling of empty set due to graph intersection

Major updates:

• [algorithms] Implementation of the new Stochastic Gradient Descent (SGD) search algorithm (#31)
• [tests] Tests for SGD included (#35)
• [environment] Upgraded base Python version to 3.7 (#34)
• [environment] Install igraph ver. 0.8.2 (conda-forge) (#41)

Minor updates:

• removed dependency to Cairo and the old plotter (#32)

Major updates:

• [command-line] The algorithm that decides the computing configuration to be used to analyze a give graph was updated to exclude the possibility to run multi-process and multi-threaded at the same time. This is still possible accessing directly to the APIs.
• [command-line] Renamed option from -T/--threads to -O/--nprocs to avoid clashes with other synonymous options
• [API] Removed all decorator methods that over-checked the sanity of the arguments of methods. These resulted to improve.
• [PyntacleInk] bug #28 "initial value" and "value" are swapped, solved
• [Tests] bug #25 "gr-finder bruteforce test fails", solved

Minor:

• [command-line] bug #23 "the command line option --type m-reach in kp-finder produces no output", solved
• [API] removed the max_distance argument from all methods
• [API] removed the seed from each method. Postponed to later versions the implementation of a clever manner of controlling randomness of number generators
  the default number of forked processes is now 1 and not equals to the total number of available processors -1
  removed shortest_path_modifications.py file

• PyntacleInk released! A standalone and interactive html file is produced in place of a static pdf.
• Several bugfixes

• fixed tests in order to accommodate changes in the output.
• reports now properly show the names of the metrics without underscores
• minor fixes in log shell of pyntacle metrics
• removed metavar from the '--suppress-cursor' option as it confilcted with the "store_true" option
• restored igraph as default sp implementation for bruteforce threading because of unresolved Numba conflicts

• correct version numbering
• fixed some log messages
• changed the help for the communities command
• removed spaces in summary report
• test for experimenting colorama on summary report
• fixed Pyntacle case for many commands, for a better clarity between the method name and the command line options
• brute-force search now reports all the sets in a separate line, making
  the interpretation and readability clearer
• greedy-optimization now reports the name of the set in a new line, making
  the interpretation and readability clearer

• fixed major bug addressing a numpy array object in greedyoptimization
• minor code cleaning

• improved decision-making regarding implementation in add_attributes
• enabled multiprocessing in kp-finder, brute-force search
• moved the --threads option in kp-finder only.
• the edge attribute "node_names" was changed to "adjacent_nodes"
• renamed file handles in importer and exporter scripts for graph and attributes methods
• redirected output of importers and exporters to stdout instead of log
• general cleanup of stdout messages

• fixed a refactoring bug in LocalTopology

• Fixed a bug in generate - small-world with the -R option: all the graphs (starting from the 2nd on) were identical. Replaced the built-in random with numpy.random

• --plot-layout option added to all the commands that produce plots.

• Minor corrections in the inline help.
