v1.0.0

First release: the code and textures the update backports share, in one library.

• 1.14's Texture Update for vanilla's blocks, items and mobs, and 1.15's enchantment glint, with the switch back to 1.12.2's look: textures.modernTextures in config/backportcore.cfg, or Backport Core's config screen. A setting made in an earlier mod's config is carried over the first time the game starts.
• Moving a world's blocks and items over from another mod's copies, on demand or when that mod is removed.
• Hiding duplicates when two mods add the same block: one of each pair keeps its recipe and creative tab.
• Planning structures on vanilla, superflat, Open Terrain Generator, Biomes O' Plenty, Realistic Terrain Generation and 1.18-height terrain.
• Registries other mods can add villager and wandering trader trades and smithing upgrades to.
• In eighteen languages, config screen included: English, Spanish (Spain and Latin America, including Argentina, Uruguay and Venezuela), Brazilian Portuguese, French, German, Russian, Simplified and Traditional Chinese, Japanese, Korean, Italian, Polish, Turkish, Ukrainian and Dutch.
