CHANGELOG
=========

0.9.4
-----

### New features

#### Added `--tac` option to reverse the order of the input.

One might argue that this option is unnecessary since we can already put `tac`
or `tail -r` in the command pipeline to achieve the same result. However, the
advantage of `--tac` is that it does not block until the input is complete.

### *Backward incompatible changes*

#### Changed behavior on `--no-sort`

`--no-sort` option will no longer reverse the display order within finder. You
may want to use the new `--tac` option with `--no-sort`.

```
history | fzf +s --tac
```

### Improvements

#### `--filter` will not block when sort is disabled

When fzf works in filtering mode (`--filter`) and sort is disabled
(`--no-sort`), there's no need to block until input is complete. The new
version of fzf will print the matches on-the-fly when the following condition
is met:

    --filter TERM --no-sort [--no-tac --no-sync]

or simply:

    -f TERM +s

This change removes unnecessary delay in the use cases like the following:

    fzf -f xxx +s | head -5

However, in this case, fzf processes the lines sequentially, so it cannot
utilize multiple cores, and fzf will run slightly slower than the previous
mode of execution where filtering is done in parallel after the entire input
is loaded. If the user is concerned about this performance problem, one can
add `--sync` option to re-enable buffering.

0.9.3
-----

### New features
- Added `--sync` option for multi-staged filtering

### Improvements
- `--select-1` and `--exit-0` will start finder immediately when the condition
  cannot be met
