 - **Falling blocks** Baritone understands the costs of breaking blocks with falling blocks on top, and includes all of their break costs. Additionally, since it avoids breaking any blocks touching a liquid, it won't break the bottom of a gravel stack below a lava lake (anymore).

 # Pathing method
-Baritone uses a modified version of A*. 
+Baritone uses A*, with some modifications: 
 
-- **Incremental cost backoff** Since most of the time Baritone only knows the terrain up to the render distance, it can't calculate a full path to the goal. Therefore it needs to select a segment to execute first (assuming it will calculate the next segment at the end of this one). It uses incremental cost backoff to select the best node by varying metrics, then paths to that node. This is unchanged from MineBot and I made a <a href="https://docs.google.com/document/d/1WVHHXKXFdCR1Oz__KtK8sFqyvSwJN_H4lftkHFgmzlc/edit">write-up</a> that still applies. In essence, it keeps track of the best node by various increasing coefficients, then picks the node with the least coefficient that goes at least 5 blocks from the starting position.
+- **Segmented calculation** Traditional A* calculates until the most promising node is in the goal, however in the environment of Minecraft with a limited render distance, we don't know the environment all the way to our goal. Baritone has three possible ways for path calculation to end: finding a path all the way to the goal, running out of time, or getting to the render distance. In the latter two scenarios, the selection of which segment to actually execute falls to the next item (incremental cost backoff). Whenever the path calculation thread finds that the best / most promising node is at the edge of loaded chunks, it increments a counter. If this happens more than 50 times (configurable), path calculation exits early. This happens with very low render distances. Otherwise, calculation continues until the timeout is hit (also configurable) or we find a path all the way to the goal.
+- **Incremental cost backoff** When path calculation exits early without getting all the way to the goal, Baritone it needs to select a segment to execute first (assuming it will calculate the next segment at the end of this one). It uses incremental cost backoff to select the best node by varying metrics, then paths to that node. This is unchanged from MineBot and I made a <a href="https://docs.google.com/document/d/1WVHHXKXFdCR1Oz__KtK8sFqyvSwJN_H4lftkHFgmzlc/edit">write-up</a> that still applies. In essence, it keeps track of the best node by various increasing coefficients, then picks the node with the least coefficient that goes at least 5 blocks from the starting position.
 - **Minimum improvement repropagation** The pathfinder ignores alternate routes that provide minimal improvements (less than 0.01 ticks of improvement), because the calculation cost of repropagating this to all connected nodes is much higher than the half-millisecond path time improvement it would get.
-- **Backtrack cost favoring** While calculating the next segment, Baritone favors backtracking its current segment slightly, as a tiebreaker. This allows it to splice and jump onto the next segment as early as possible, if the next segment begins with a backtrack of the current one. <a href="https://www.youtube.com/watch?v=CGiMcb8-99Y">Example</a>
+- **Backtrack cost favoring** While calculating the next segment, Baritone favors backtracking its current segment. The cost is decreased heavily, but is still positive (this won't cause it to backtrack if it doesn't need to). This allows it to splice and jump onto the next segment as early as possible, if the next segment begins with a backtrack of the current one. <a href="https://www.youtube.com/watch?v=CGiMcb8-99Y">Example</a>
+- **Backtrack detection and pausing** While path calculation happens on a separate thread, the main game thread has access to the latest node considered, and the best path so far (those are rendered light blue and dark blue respectively). When the current best path (rendered dark blue) passes through the player's current position on the current path segment, path execution is paused (if it's safe to do so), because there's no point continuing forward if we're about to turn around and go back that same way. Note that the current best path as reported by the path calculation thread takes into account the incremental cost backoff system, so it's accurate to what the path calculation thread will actually pick once it finishes.

+Impact 4.4 has Baritone included.

+
+### Official Release (Not always up to date)
+https://github.com/cabaletta/baritone/releases
+
+For Impact 4.3, there is no Baritone integration yet, so you will want `baritone-standalone-X.Y.Z.jar`.
+
+Any official release will be GPG signed by leijurv (44A3EA646EADAC6A) and ZeroMemes (73A788379A197567). Please verify that the hash of the file you download is in `checksums.txt` and that `checksums_signed.asc` is a valid signature by those two public keys of `checksums.txt`. 
+
+The build is fully deterministic and reproducible, and you can verify Travis did it properly by running `docker build --no-cache -t cabaletta/baritone . && docker run --rm cabaletta/baritone cat /code/dist/checksums.txt` yourself and comparing the shasum. This works identically on Travis, Mac, and Linux (if you have docker on Windows, I'd be grateful if you could let me know if it works there too).

-- Run the Gradle task `setupDecompWorkspace`
-- Run the Gradle task `genIntellijRuns`
-- Refresh the Gradle project (or just restart IntelliJ)
-- Select the "Minecraft Client" launch config and run

+$ gradlew build
 ```
 
+To replace out Impact 4.4's Baritone build with a customized one, switch to the `impact4.4-compat` branch, build Baritone as above then copy `dist/baritone-api-$VERSION$.jar` into `minecraft/libraries/cabaletta/baritone-api/1.0.0/baritone-api-1.0.0.jar`, replacing the jar that was previously there. You also need to edit `minecraft/versions/1.12.2-Impact_4.4/1.12.2-Impact_4.4.json`, find the line `"name": "cabaletta:baritone-api:1.0.0"`, remove the comma from the end, and entirely remove the line that's immediately after (starts with `"url"`).
