Minecraft's Needed Blocks (Swamp Update: Part 3 Beta)
Minecraft's Needed Blocks adds a swamp-themed block set for world generation, with stone, wood and ore variants that Tremendous Tweaks built for the Swamp Update line.
What it does
Swamp Stone is the centerpiece, with stairs, slabs, walls and other shape variants alongside decorative stone blocks. The set is meant to fill out builds and terrain that vanilla stone does not cover, and the swamp ore family includes Swamp Stone Shard Ore along with ore blocks in both stone and deepslate versions.
Wood content follows the same theme. Infected logs, stripped logs and regular stripped wood come with a full set of infected planks, stairs, slabs, fences, gates, boats, chests, buttons, pressure plates, doors, trapdoors, signs and hanging signs. Swampy Bloom is a separate plant block added to the swamp palette.
The mod runs on the client and on the server, so both sides need it and every player on a server that runs it needs it too. It is published for Fabric only, with files for 1.21.8, 1.21.9, 1.21.10 and 1.21.11 and the latest file, 1.3.0 for 1.21.11, in the beta channel. The code is under the MIT License and the mod is not open source. EMI, Just Enough Items and Roughly Enough Items are optional recipe viewers that can display its recipes.

How it compares
Pale Oak Backport is a Fabric mod for 1.21.1 under the MIT License and is not open source; it targets a single version, while this mod covers 1.21.8 – 1.21.11. Replant Swamp Oak is Fabric-only, also MIT licensed and not open source, with files for 1.21.1 – 1.21.11, so its range overlaps with this mod but it adds a sapling rather than a block set. Pricks 'n' Planks is client and server, uses All rights reserved and targets 1.21.6 – 1.21.11.
