 #### Variable-Sized Number
 
-`VAR_INT` and `VAR_LONG` are alternatives of `INT` and `LONG` respectively where the value is encoded to be as small as possible. This is done by encoding seven bits at a time, using the upper bit as a marker of whether there is more data for this number. Numbers between 0 and 2^28-1 for integers or 0 and 2^56-1 for longs will be sent shorter or equal to the number of bytes in a integer or long, respectively. If the values of your numbers are normally in this range and generally at the lower end of it, then these variable stream codecs should be used.

 #### Trusted Tags
 
-`TRUSTED_TAG` and `TRUSTED_COMPOUND_TAG` are variants of `TAG` and `COMPOUND_TAG`, respectively, that have an unlimited heap to decode the tag to, compared to the 2MiB limit of `TAG` and `COMPOUND_TAG`. Only the [block entity data packet][blockentity] and [entity data serializers][entityserializer] use these trusted variants.
