### 2.2.0
- fix bugs where pretty printing didn't work right for
leave-space-for-unqualified
- add `format: columns=n` field
- separate qualify-as fields with ; instead of ,
- fix a bug where I didn't allow _ in unqualified import names
- better error reporting
### 2.1.0
- unqualified syntax changed to support multiple imports per module
- add `format: leave-space-for-qualified` and `format: no-group`
- add import-as config option
E.g. import Data.Text.Lazy as DTL, instead of always having to qualify
as a suffix, like Lazy, or Text.Lazy.
- various bugs with unqualified imports
#### 2.0.0
- add support for unqualified imports for explicitly configured symbols, via
the `unqualified` field in `.fix-imports`
- significant speed improvement, reuse the loaded pkg index instead of asking
ghc-pkg find-module
- --debug now emits timing metrics
- import-order-{first,last} are exact matches, or are prefix matches if they
have a trailing dot
- prio-module-{high,low} are now exact matches instead of prefix
#### 1.1.0
- Rename import-order to import-order-first, and add import-order-last.
#### 1.0.5
- support haskell-src-exts > 1.16
- add 'language' field to .fix-imports, to turn on local extensions
#### 1.0.3 and 1.0.4
- upgrade to haskell-src-exts-1.16
#### 1.0.2
- Fix bug where a qualified import with >1 dot wasn't found. And don't
mess with Prelude.
#### 1.0.1
- Fix a bunch of bugs: properly recognize unqualified imports as imports,
never import the current module, don't pick up modules with the same suffix
but a different name.
#### 1.0.0
- Change name from FixImports to fix-imports, which is more unixy.
- Change ghc-pkg parsing from String to Text. It's noticeably faster.
- Add a more flexible system for prioritizing imports.
When there are several possibilities for a module name, they are all given
to a single function to decide. The config file moved from
fix-imports-priority to .fix-imports and can now specify sort orders for
packages and modules by prefix.
- Make -i includes for non-existent dirs ignored instead of causing an
error.
