# Changelog



## 1.1.2



- Added `FeistelCipher.backfill_sentinel/0` exposing the sentinel value (`-1`) that marks not-yet-encrypted rows for triggers and backfill.



## 1.1.0



- Added `backfill_for_v1_column/5` for filling encrypted columns on existing rows.

- Backfill treats both `NULL` and `-1` as pending values.

- Added and clarified backfill documentation for trigger-based workflows.



## 1.0.0



- Renamed `bits` to `data_bits`.

- Added `time_bits`, `time_bucket`, `time_offset`, and `encrypt_time`.

- Introduced v1 PostgreSQL function and trigger APIs with `_v1` suffixes.

- Kept `time_bits: 0` as the backward-compatible path for v0.14.x and v0.15.x users.
