Delivery
When mail and seeds are inserted into a Mailbox, its front hatch will open, allowing nearby Pigeons to pick mail up and start a delivery- Pigeons can deliver mail (and return to) unloaded chunks without issues
- Delivering Pigeons ascend high above the clouds to make traveling long distances more efficient, thus they can only be seen while nearby a Mailbox
Courier Bat
Express deliveries at night- Delivers mail two times faster than Pigeons
- Will find Mailboxes with Spider Eyes anywhere in the world

- Improved wandering:
- Pigeons now perch occasionally on leaves and wooden blocks, similar to parrots
- Reduced wandering movement speed slightly
- Other minor changes and fixes
- Improved and fixed pigeon's "home" mechanic:
- When a Pigeon exits Pigeonhole - it becomes its home position
- Pigeon will not wander outside 24 block radius of it
- Pigeon will pathfind back to the home radius if it happens to be outside of it
- Pigeon will forget its home after 3 in-game days of not resting inside a Pigeonhole, and will be free to wander off anywhere
- Pigeon can still enter any Pigeonhole when it already has a home, which will make it its new home
- Small adjustment to pigeon spawning in village to reduce spawn counts in some cases
- Increased Pigeonhole location distance
- Minor adjustments to predator avoidance behavior
- Tired pigeons fly slower now
- Pigeons named "Drumstick" will have a slightly chonkier model
- Minor tweaks of Pigeon textures:
- Slightly darkened underside of wings and tail.
- Fixed texture of the underside of a Pigeon's wing being flipped.
- Fixed wings of pigeons sitting in boats or seats having wrong position
- Fixed position of Create's Conductor and Logistics hat on a Pigeon
- Fixed pigeons exiting (and re-entering immediately) the Pigeonhole when it's raining without thunderstorm
Pigeonhole
- Improved pigeon behavior when the block is smoked
- Waste scooping now uses loot table for drops
- Fixed waste generation of tired pigeons being less than intended
Mailbox
- Adjusted Mailbox collision shape to better reflect the model
- Fixes some cases of wrong culling
Services
- Equine Assurance Bureau notice letter sending is now triggered by taming an animal instead of at random to all players at once
- Every sent letter decreases the chance of the next. Sending them Gold Block also decreases the chance
- Taming animals other than horses have 1 in 5 chance to trigger sending (which then also stacks with reduced chance of sending)
- Reduced virtual distance to service addresses:
- Mail Service (1000 -> 0)
- Automated Supply Service (2000 -> 1000)
Integration
- Added Paper Box recipe using Cardboard from Create
- Packages from Create can be delivered now
- Address Tag is still required, regardless of the address on the package. Address Tag can be applied automatically with crafters
- When moving mail recipe ingredients into a Package with JEI - address of the recipe will be remembered and applied when items are packed, consuming an Address Tag
- Fixed mailing recipe category not displaying correctly with _EMI_ and _TooManyRecipeViewers_.
Misc
- Fixed a crash occurring when a service address returned unprocessed items in a craft (sending back remaining items)

#### Mail Recipes
Added a new way to craft items by sending a Package with ingredients to the service address.
- Works similarly to the shapeless crafting.
- Results are returned using the same courier, or with a service courier, if some of the ingredients were unprocessed.
- Data-driven.
- Can give experience. Applied to the resulting package.
- Shown in **JEI**
- Clicking on an arrow in the Mailbox menu, or on a box in the Paper Box menu will show available recipes.
Included recipes:
- Payback Tag
- no longer craftable in the Crafting Table
- Seal Stamps with custom impressions
- Rotten Flesh -> Leather
- Saddle
- Name Tag
- Tuff, Dripstone, Calcite
- Glow Ink Sac
- Book and Quill and Letter and Quill
- Lost Mail
- Has random loot inside
- Letter Broadcasting
- Sends copies of the letter to all existing player-default mailboxes.
Package
- Added
envelope:package_experienceitem component. Awarded when package is opened. - Using the package while holding [**Sneak**] will unpack it without opening the menu.
- Fixed overlays not rendering over package slots.
- Fixed being able to insert items into opened package, if items were the same.
Payback Tag
- Added drag and drop from JEI support.
- Added request duration selector.
- Controls how much time buyer will have to pay for the mail.
- Item texture changes slightly based on duration defined.
- Using the tag while holding [**Sneak**] will clear the data from it.
- Menu UI/UX improvements.
- Changed
envelope:payback_tag_contentsitem component: its structure is now the same asenvelope:mail_payback_request. delivery.payback_timeout_minutesconfig option was replaced by threepayback.request_duration_<duration>options.
Address
- Player address type definition has been changed. Field
idis nowname:{ type:"player", name:"mortuusars" } - Service addresses are now data-driven
- Address component now references registered definition by its key:
{ type:"service", definition:"envelope:mail_service" } - Added "custom" address type:
{ type:"custom", name:{translate:"display.name"} } - Can be used for display purposes (commands, scripts, etc.). Cannot receive mail.
- Unknown address is now a separate type:
{ type:"unknown" }
Service Addresses
- Definition is data-driven.
- For use in recipes or custom handlers.
#envelope:hiddenservice address tag can be used to hide the address from suggestions and its recipes from JEI.- Addresses that have recipes will show up in JEI as an ingredient.
- Querying their uses (R-Click or [U]) will show available recipes associated with that address.
- Added **Equine Assurance Bureau** sending "spam" letters.
Delivery
- Added support for Service address "drop-off" handlers.
- They can be defined in code (for addons) or through KubeJS.
- _Drop-off handler is responsible for actually deciding what happens with delivered mail (consume/return/reply)._
KubeJS
- Added
EnvelopeEvents.registerServiceDropOffHandlersevent. - Added
EnvelopeEvents.handleMailDropOffevent. - Called before most of the regular logic is processed.
- Can be used to modify drop-off of any address type.
- No documentation yet.
Misc:
- Slightly improved Pigeon pathfinding around blocks, should get stuck a bit less now .
- Added **Address Tag** and **Payback Tag** application recipes.
- Applying **Address Tag** and **Payback Tag** in GUI now consumes 1 tag per mail, instead of 1 per stack.
- Payback Box** and **Payback Package** now show full time remaining when [**Shift**] is held.
- Updated some address type icons (little flags)
- Moved seal textures from
textures/gui/sealtotextures/sealfolder. - Moved letters and numbers seal impressions into their respective subfolders. Example:
envelope:c->envelope:letter/c - Fixed total delivery distance calculation in debug-mode overlay.
- Rewrote some parts of Delivery Log, mostly internal work, but there are some minor user-facing changes as well.
- Small updates of **Address Tag**, **Payback Box** and **Payback Package** menu textures.
- Small change to how
envelope:payback_subjectcomponent is defined. - Renamed
mail_service_payback_department.dattoenvelope_mail_service_payback_department.datin _level/data_. - Fixed couriers spawned after delivery is finished (when ended in unloaded chunk) not being tired.
- Fixed leashed pigeons being able to enter a Pigeonhole.
