core: v0.9.0

0.9.0 (2024-04-10)

⚠ BREAKING CHANGES

• allow custom seed when using targetingKey override for fractional op (#1266)
  • This is a breaking change only to the extent that it changes the assignment of evaluated flag values.
    Previously, flagd's fractional op would internally concatenate any specified bucketing property with the flag-key.
    This improved apparent "randomness" by reducing the chances that users were assigned a bucket of the same ordinality across multiple flags.
    However, sometimes it's desireable to have such predictibility, so now flagd will use the bucketing value as is.
    If you are specifying a bucketing value in a fractional rule, and want to maintain the previous assignments, you can do this concatenation manually:
    { "var": "user.name" } => {"cat": [{ "var": "$flagd.flagKey" }, { "var": "user.name" }]}.
    This will result in the same assignment as before.
    Please note, that if you do not specify a bucketing key at all (the shorthand version of the fractional op), flagd still uses a concatentation of the flag-key and targetingKey as before; this behavior has not changed.
