Upcoming features

Journey's End (1.4)
"Terraria: Journey's End", the fourth and final major update of Terraria, is currently under development. While originally announced to be released in 2019, it is now currently planned to be released on Terraria's 9th birthday, May 16, 2020. Until June 10, 2019, it was announced to be released as 1.3.6.

It will include a re-visit of all elements of Terraria. Things that may have felt outdated or obsolete due to the introduction of newer content will be renewed and new elements will be included in order to "flesh out the overall experience", including over 1000 new items.

On the official Terraria Discord server, Cenx mentioned that 1.4 will have "a form of creative mode". This mode "won't just give you everything. It will all need to be earned", unlike traditional creative modes in other games. This was later confirmed to be Journey mode.

Gameplay

 * Journey mode. It is a slightly easier version of the game, but also gives players the option to duplicate items and control the difficulty, spawn rates, time and weather.

 * The player starts with an Iron Shortsword, Iron Pickaxe, Iron Axe, Iron Hammer, Finch Staff, 100 Torches, 100 Rope, a Magic Mirror and Fledgeling Wings.
 * Players will have access to infinite numbers of any items that they "research", (called "duplication" by the game) and each item has a specified amount that must be researched before duplicated. Items such as torches and rope require a stack of 100 to be duplicated, while tools and weapons often require 1.
 * The Power Menu holds a list of options unique to Journey mode that allow players to customize how they play, duplicate and research items, change time and weather, and more.
 * The Duplication Menu is where all researched items can be duplicated to the player's desire. Items here are separated into seven categories, appearing to be Weapons, Armor, Blocks, Furniture, Accessories, Consumables, and Other. The menu also allows players to search for items as well.
 * The Research Menu is where items can be researched so they can be duplicated. The menu will list how many items the player needs to research the item, and once acquired, the player can press "Research" to add the item to the Duplication Menu.

The second option shows a gust of wind, and the fourth option shows a rain cloud, but it is currently unknown what either of these options do.
 * The Godmode option enables and disables Godmode. Godmode will render the player invulnerable to any damage so long as the option is active.
 * The Increased/Normal Placement Range option allows the player to place blocks farther than normal on the screen. It is unknown if this allows unlimited placing range.
 * The Infection Spread option allows players to enable and disable biome spreading.

 * A new mechanic called "Block Swap". Similar to the "Quick Wall Swap" feature, this feature grants the ability to replace blocks based on the highest pickaxe power of a pickaxe in the player's inventory without requiring to mine them first. This also includes furniture like chests, which do not need to be emptied prior to being replaced.

As of April 29th, 2020, tModLoader has been announced as free for Terraria. It will launch with Terraria 1.4 on May 16, 2020 and is planned to be compatible with Terraria 1.3.5.3. Further plans include the ability to utilize the Steam Workshop to host mods under the tModLoader banner, and tModLoader support for 1.4 after it releases.

Terraria series
Following the release of the Terraria 1.3 update, lead developer Redigit had moved on to working on another project, though developers Yoraiz0r and Skiphs were continuing to update Terraria. Redigit returned to work with the team to develop 1.3.5, and is heavily involved in 1.4.

A spin-off of Terraria, Terraria: Otherworld, was under development, until it was cancelled.

Redigit stated that he plans to later release Terraria 2, a separate game from the canceled Terraria: Otherworld, although little information is known about the nature or content in the possible upcoming sequel.
