# Setting the libtool versioning
###################################################################################
# #
# To set the version of the library, libtool provides the -version-info #
# parameter, which accepts three numbers, separated by colons, that are called #
# respectively, current, revision and age. Both their name and their behavior, #
# nowadays, have to be considered fully arbitrary, as the explanation provided #
# in the official documentation is confusing to say the least, and can be, in #
# some cases, considered completely wrong. #
# https://autotools.io/libtool/version.html #
# #
###################################################################################
#
# How to work with the libtool versioning?
#
# Follow the followings steps from top to bottom. This means always start at point 1
# if you plan to make a release and change the values.
# Every new library starts with a version 'current' (short 'c') = 0
# 'revision' (short 'r') = 0
# 'age' (short 'a') = 0
#
# Update the libtool versioning only after the release of a public release of libcoap.
# Go through the following checklist from top to bottom and check your needs, following
# the reminded changes if you can say "Yes" for specific check.
#
# 1. Only existing code has changed, no functional changes
# If the library source code has changed but *no* new symbols were added at all
# since the last update, then increment revision (c:r:a becomes c:r+1:a).
# This is usually happen if the existing source of a function was changed for
# bug fixing e.g.
#
# --> Increase the 'LT_LIBCOAP_REVISION' value with *every* new software release
# within one release cycle.
#
# 2. Interfaces were added, functions have changed or are removed
# If any interfaces [exported functions or data] have been added, got internal
# changes that implies a different behavior or removed and by this the visible
# symbols have changed since the last update, increment current, and set
# revision to 0 (c:r:a becomes c+1:r=0:a).
#
# --> Increase the 'LT_LIBCOAP_CURRENT' value whenever as an interface has been added
# or removed. This implies also a API change! You mostly have to change the
# 'libcoap_major_version' or at least 'libcoap_minor_version' then too!
# --> Set 'LT_LIBCOAP_REVISION' to 0.
#
# 3. Interfaces were added but none removed or changed
# If any interfaces have been added since the last public release and non of the
# existing interfaces were removed and existing interfaces have not changed internally
# functionality then the new library is backward compatible. Existing binaries can
# use the new library the same than as the existing old library without loosing
# existing functionality or breakage.
# Increase age by 1 (c:r:a becomes c:r:a+1).
#
# --> Increase the 'LT_LIBCOAP_AGE' value only if the changes made to the ABI are
# backward compatible.
#
# 4. Interfaces were removed or have functional changes
# If any interfaces within the library have been removed since the last public
# release or got some internal changes that let the interface act different than
# before, then set age to 0. The library isn't backwards compatible.
#
# --> Set 'LT_LIBCOAP_AGE' to 0.
