• Call Of The Wild (COTW) no longer cares if entities of the same type are nearby when attempting to summon a new entity
• Fixed a bug where COTW summon limit was global instead of per player
• If you are playing in 1.14 mcMMO will now summon cats instead of ocelots
• The default summon limit for COTW is now per player instead of global which is how it should be, for wolves this defaults to 2, for other entities it defaults to 1
• The COTW setting named Summon_Max_Amount in config.yml has been renamed to Per_Player_Limit
• By default players are no longer allowed to breed COTW summoned animals with other animals, you can turn this off (see the notes)
• If a player tries to breed animals with a COTW animal and the server settings prevent this, they are informed via a message that it is not allowed
• If the COTW summon has a lifespan, players are now informed about this lifespan when the entity is first summoned
• COTW entities now send the player a message when they die, time out, or get removed through other means
• COTW summons now have their name prefixed with some colored text to to make it easier to identify them.
• COTW summons now despawn if their owner logs out
• There is now a small 150ms window in which you cannot summon an entity via COTW to prevent accidentally summoning extra entities
• COTW Horses, Cats, and Wolves now always spawn in as adults
• Changed the sound effect for COTW (Fireworks -> Pop)
• Most COTW messages have been tweaked and new COTW messages have been added
• Added new setting to experience.yml 'ExploitFix.COTWBreeding' - Prevents breeding with COTW summoned entities when set to true, defaults to true
• Removed the 'mcmmo.ability.taming.callofthewild.renamepets' permission node as it is seen as unnecessary

NOTES:
I plan to rework Call of The Wild (COTW) significantly in the upcoming content patch, until then I have made several tweaks to it.

COTW Summoning Requirement Changes
It is intentional that you are not supposed to be able to COTW summon something that you already have tamed, but mcMMO was not checking this properly.
So previous to this patch, if you tried to summon a wolf and wolves were nearby, it would fail. This is not intentional behaviour and was a bug.
The correct behaviour is that if you try to summon a wolf and you already have wolves, it should fail.
I was fixing this bug when it occurred to me, why do we even care if nearby tamed wolves owned by you exist if you are trying to summon a temporary one?
As a result of this train of thought, I have removed this restriction on COTW and several other tweaks have been made as a result of this line of thinking.
There was also an issue involving how many COTW entities could be out at once, for some reason the limit was applied globally and defaulted to 10, so if 10 players had COTW entities out no one else would be able to summon anything. I have fixed this.
You can set the lifespan to 0 in the config to make it so that COTW entities last until a server restart or the player logs out.

COTW Breeding Change
It was never intentional for COTW summoned entities to be breedable, by default they will not be. You can change this by setting 'ExploitFix.COTWBreeding' to false in experience.yml
