 # Requirements
-TAB does not depend on any other plugins. The experience can however be enhanced by installing other plugins, see below.
-
-## Java
-TAB's shared module is compiled with Java 8. For the platforms themselves, TAB does have a higher requirement, however, it does not require a Java version higher than the server software itself does. Specifically:
-* Fabric and NeoForge require Java 25
-* Velocity requires Java 17
-* Bukkit and BungeeCord are ok with Java 8
+TAB does not depend on any other plugins. The experience can however be enhanced by installing other plugins, see below. There is also no additional Java version requirement. If your server runs on your Java version, TAB will too.
 
 # Supported server software and versions
 With the introduction of new Minecraft versions, it is becoming harder and harder to support many versions in the same jar, eventually making it impossible since Minecraft 26.1.  
 **As a general rule, if you want the latest TAB version for your server please use [Modrinth](https://modrinth.com/plugin/tab-was-taken)'s download filter where you can select your server software and version and you'll get the latest jar.**
 
-Currently, the latest Minecraft version supported by TAB is 26.1.2. When new versions come out, TAB is always updated soon after to support them.
+Currently, the latest Minecraft version supported by TAB is **26.2**. When new versions come out, TAB is always updated soon after to support them.
 
 If your server software and version is reasonably popular and TAB hasn't been backported to that version in a very long time, you may [request a backport](https://github.com/NEZNAMY/TAB/issues/new/choose) (unless backports to that version are no longer offered, see below).  
 Since TAB 6.0.0, Minecraft 1.x started taking hits with each subsequent versions - Bukkit versions started disappearing and **modded platforms no longer offer backports of TAB 6.0.0+ to MC 1.x** (this is because the build scripts had to be massively changed for MC 26+).

 # About
-This features gives you control over Minecraft's scoreboard objective feature with BELOW_NAME slot.
-This line is displayed below the nametags of all player entities in game. It is not possible to explicitly disable this feature for NPCs; however, this goal can be achieved (see below for more info).
-It is only visible when within an 8-block range of the player (the range is hardcoded in the client and cannot be changed with a plugin).
+This features gives you control over Minecraft's scoreboard objective feature with BELOW_NAME slot.  
+On Minecraft 1.21.11 and below, it is visible on all player entities (including NPCs). On 26.1.x, it is visible on all player entities and all named entities (such as holograms), making this feature unusable. On 26.2 and above, it only appears on entities with a score assigned (the ideal implementation).  
+It is only visible when the target player is within a 10-block range of the viewer (the value is configurable since Minecraft 26.1).

+## Example 5 - Conditionally hiding belowname for 26.2+ viewers
+Since Minecraft 26.2, belowname only appears on entities with a score. This can be used to disable the belowname on players with a condition. We are trying to achieve a condition like this: "If something, hide belowname for 26.2+ viewers".  
+TAB is made to reset score (= hide belowname) of target players for 26.2+ viewers (<26.2 viewers are not affected, resetting scores for them would result in `fancy-value-default` to be shown, which is undesirable) if `fancy-value` evaluated to an empty string. Therefore, we will need to make a [relational condition](https://github.com/NEZNAMY/TAB/wiki/Feature-guide:-Conditional-placeholders#relational-conditions) that checks the viewer's version and returns empty string if some condition is met.  
+Here is an example of hiding it if target player has less than 10 health (5 hearts):
+```
+conditions:
+  belowname-health:
+    conditions:
+      - "%viewer:player-version-id%>=776"  # 26.2 uses 776, check for viewer's version, not target player's
+      - "%health%<10"  # This should check target player's health
+    type: AND
+    true: ""  # Viewer is on 26.2+ and target has less than 10 health, return empty string to hide it
+    false: "%health%"  # Display health as normal
+```
+Then, use this condition as a relational condition (because it checks both viewer and target players):
+```
+belowname-objective:
+  fancy-value: "%rel_condition:belowname-health%"

+## Additional note 1 - Choosing the correct AND / OR type
+Sometimes you want to combine multiple expressions using `AND` or `OR`. When doing this, you must pick the correct one based on your needs.  
+A common mistake is trying to turn spoken language directly into config, which can be wrong.
+
+For example, you say you want to display scoreboard in servers `server1` **and** `server2`. As such, you may accidentally use `type: AND` or `;` in short format (`%server%=server1;%server%=server2`). This is, however, wrong, because that would mean your server must be `server1` **and** `server2` at the same time, which is obviously impossible. The correct type is `OR` here (`|`). So instead of thinking "I want to display scoreboard in `server1` **and** `server2`", you should think "I want to display scoreboard if player is in `server1` **or** `server2`.

+# Ways of optimizing
+## #1 - [All platforms] Static text instead of placeholders
 Static text doesn't need to be refreshed periodically, resulting in better performance.
 Some placeholders can be replaced with static text, such as placeholder for max player counts,
 since that value doesn't change at runtime.
 Another option is to configure prefixes per-group in config
 instead of using placeholders to take those values from your permission plugin.
 
-# #2 - [All platforms] Placeholder refresh intervals
+## #2 - [All platforms] Placeholder refresh intervals

+# Netty false positive in spark reports
+When taking a spark report with all threads monitored instead of just the server thread using `--thread *` argument (or on a proxy where this is enabled by default since there is no main thread to monitor by default), you may notice high usage (both CPU and RAM) in netty thread when grouping threads by plugin. **Vast majority of that usage is false positive.** Let's go over why this is the case and how to read the real value.
+
+## Why there is a false positive
+When listening to an event, the server fires the events in a loop, where each event is the end point. As such, measuring every event handler individually is accurate. Here is how the hierarchy looks with example numbers:
+```
+Event processing in loop (6ms total)
+↳ Plugin 1 (1ms)
+↳ Plugin 2 (2ms)
+↳ Plugin 3 (3ms)
+End of loop
+```
+As such, the measured values are accurate and spark is able to separate each event handler based on plugin. Command executions and repeating tasks are even simpler.
+
+The issue is with netty injection. The purpose is to listen to outgoing packets, react to them and possibly modify them. Unlike with events, these are not processed in parallel, but every handler forwards the packet to the next one (or doesn't if it should be cancelled). As such, the hierarchy looks like this (simplified version):
+```
+Beginning (12ms total)
+↳ Plugin 1 (1ms self, 12ms total)
+  ↳ Plugin 2 (1ms self, 11ms total)
+    ↳ Plugin 3 (1ms self, 10ms total)
+      ↳ Minecraft encoder (10ms self)
+```
+As such, spark will show 12ms total for Plugin 1, even though its own usage is only 1ms. This is due to a limitation of the design of Spark in combination with how netty handlers work. This is only the case for plugins with their own netty injection, it does not apply to plugins that use ProtocolLib, because that one offers event-like functionality explained above. In this case, the usage shown in spark report is 100% accurate.
+
+## How to read the real value
+An actual usage of the netty threads can be split into 2 parts:
+* Listening to outgoing packets
+* Sending packets, which causes it to go though the pipeline and then encode
+
+### Packet listening usage
+This one is simple and accurate. Take the shown number, expand the call stack and subtract `io.netty.channel.ChannelDuplexHandler.write()` usage, which is forwarding the packet to the next handler and would be there even if that plugin wasn't injected.  
+Let's take a look at a practical example:
+<img width="1091" height="266" alt="image" src="https://github.com/user-attachments/assets/6d9e8c25-8375-413b-ab9b-31b52ff9262c" />
+
+Here, spark reports `31.71%` usage by TAB. However, `30.87%` of it is forwarding it to the next handler (`io.netty.channel.ChannelDuplexHandler.write()`), which forwards it to the next one, until eventually the server encodes the packet. Therefore, TAB's real usage by listening to outgoing packets in this report is `31.71%` - `30.87%` = `0.84%`. Much less than what you originally see.
+
+### Sending packets
+Sadly, this one is impossible to calculate directly. When a packet is scheduled for sending, it is only added to a queue, then consumed by a netty thread, not the caller thread. At that point we are losing information about where a packet comes from.  
+There is some good news though.
+
+First, vast majority of plugins barely send any packets. For example PlaceholderAPI is just an interface between plugins, chat plugins only modify chat message packets that would be sent anyway, ViaVersion same thing, and so on...
+
+
+Second, plugins that send a lot of packets usually send the kind that the server either doesn't send at all, or not much. Expanding the data from the previously shown report gives us this:
+<img width="1083" height="496" alt="image" src="https://github.com/user-attachments/assets/c6157e78-ef6a-4d9c-b4b7-7c7b32dd14f8" />
+
+Here we can see that encoding team packets took 0.99%. Since TAB is the only team plugin you need for managing players, it is safe to assume most, if not all of it comes from TAB.  
+Same here - 0.13% from header and footer.
+<img width="1085" height="93" alt="image" src="https://github.com/user-attachments/assets/559dce56-83d3-49b2-9f4b-29b6124f944c" />
+
+Sadly there are other operations needed than just encoding packets, such as allocating buffers and other, so this part is not that simple anymore.

+# MiniPlaceholders
+On **Velocity**, TAB integrates with [MiniPlaceholders](https://github.com/MiniPlaceholders/MiniPlaceholders) when the plugin is installed. TAB automatically detects and resolves MiniPlaceholders placeholders in config text, including global, per-player, and relational ones. Placeholders use angle brackets, with the expansion and name separated by an underscore (for example `<luckperms_prefix>`), and arguments added after a colon (for example `<luckperms_meta:key>`). See the [MiniPlaceholders placeholder list](https://miniplaceholders.github.io/docs/user-guide/Placeholders) for all available placeholders. TAB also registers its own expansion, offering placeholders such as `<tab_tabprefix>` and `<tab_placeholder:name>`. The `%placeholder%` syntax remains reserved for [PlaceholderAPI](https://github.com/PlaceholderAPI/PlaceholderAPI) (via TAB Bridge on Velocity).
+
+> [!WARNING]
+> TAB's gradient syntax (`<#RRGGBB>Text</#RRGGBB>`) is a compatibility layer that TAB rewrites before parsing, it is more fragile than native [MiniMessage](https://docs.advntr.dev/minimessage/format.html) gradients (`<gradient:#RRGGBB:#RRGGBB>Text</gradient>`). On **Velocity**, this is especially problematic because [MiniPlaceholders](https://github.com/MiniPlaceholders/MiniPlaceholders) parses MiniMessage *before* TAB can rewrite its gradient syntax. For example, placeholder output like `<#E0B11E>MyServer</#FF0000>` is interpreted by MiniPlaceholders as a hex color tag (`<#E0B11E>`), but `</#FF0000>` is not recognized as a gradient closing tag, so the formatting breaks. Prefer native MiniMessage syntax in placeholder output (e.g. `<gradient:#E0B11E:#FF0000>MyServer</gradient>`).
