      "value": "gnark is a zk-SNARK library that offers a high-level API to design circuits. Prior to version 0.9.0, for some in-circuit values, it is possible to construct two valid decomposition to bits. In addition to the canonical decomposition of `a`, for small values there exists a second decomposition for `a+r` (where `r` is the modulus the values are being reduced by). The second decomposition was possible due to overflowing the field where the values are defined. Upgrading to version 0.9.0 should fix the issue without needing to change the calls to value comparison methods."

Antes de la versi\u00f3n 0.9.0, para algunos valores en el circuito, era posible construir dos descomposici\u00f3n v\u00e1lida en bits. Adem\u00e1s de la descomposici\u00f3n can\u00f3nica de \"a\", para valores peque\u00f1os existe una segunda descomposici\u00f3n para \"a+r\" (donde \"r\" es el m\u00f3dulo por el que se reducen los valores). La segunda descomposici\u00f3n fue posible debido al desbordamiento del campo donde se definen los valores. La actualizaci\u00f3n a la versi\u00f3n 0.9.0 deber\u00eda solucionar el problema sin necesidad de cambiar las llamadas a los m\u00e9todos de comparaci\u00f3n de valores."
