Since last year's server, a whole lot of new additions were introduced to Cobblemon, such as:
>Pokédex items and functionality
>Poké Rods and fishing gameplay
>Flat level battle options
>Doubles, triples and multi battles
>Village Poké Centers
>Native NPC functionality
>A whole lot of new Pokémon, blocks, structures, and items

Hopefully the 1.7 update drops before the summer because it will be introducing many heavily requested features like:
>Riding: https://youtu.be/dvV84dQcCx0
>Breeding: https://youtu.be/_DUafSfls5Q
>Cooking: https://youtu.be/Z3rAnAaLe9I
>And TMs and type gems! https://youtu.be/zRjnrcEKso8

If the update doesn't release by then, there should hopefully be a stable-ish snapshot out at least. It would be a shame to miss out on the above features.

As well as that, there are many new mods and add-ons released that improve the Cobblemon experience. We can use them to make the server more fun. There are add-ons that add Mega Evolutions, Pokémon-inspired cosmetic hats, aggressive wild Pokémon, the PokéNav, and much more!
