+## 2.6.0 - 2023-07-07
+### Added
+* Weeder now supports GHC 9.6.
+### Changed
+* Weeder now uses [TOML](https://toml.io) as a configuration format. Please see Weeder's `README` for more information on the configuration format.
+* Weeder now sorts weeds in a single file by ascending line number
+### Fixed
+* Weeder now internally adds declarations once. This shouldn't result in any user visible changes, but may improve performance.

+## [`2.5.0`][v2.5.0] - *2023-01-23*
+
+- Weeder has been upgraded to support GHC 9.4 (only). As this changes the
+  format of `.hie` files accepted, this is a major version bump. Thanks to @tfausak!
+
+## [`2.4.1`][v2.4.1] - *2023-01-05*
+
+- Build with `lens-5.2`
+
+## [`2.4.0`][v2.4.0] - *2022-05-22*
+
+- Weeder has been upgraded to support GHC 9.2 (only). As this changes the
+  format of `.hie` files accepted, this is a major version bump.
+
+## [`2.3.1`][v2.3.1] - *2022-05-21*
+
+This is the last release of `weeder` compatible with GHC 9.0.
+
+- Weeder now analyzes top-level pattern bindings. For example, with the following input:
+
+    ```haskell
+    module Dep (a, b) where
+
+    xxx :: Int
+    xxx = 3
+
+    a, b :: Int
+    (a, b) = (xxx, 1)
+    ```
+
+    ... `weeder` will determine that both `a` and `b` depend on `xxx`. While this is an over-approximation, it prevents weeder from reporting false positives. For more information, see [#92](https://github.com/ocharles/weeder/issues/92).
+
+- Corrected a typo in `--help` ([#96](https://github.com/ocharles/weeder/pull/96)).
+- Shorten the help text for `--require-hs-files` ([#97](https://github.com/ocharles/weeder/pull/97)).
+- Allow `algebraic-graphs-0.6` ([#95](https://github.com/ocharles/weeder/pull/95)).
+- Allow Dhall 1.41 ([#99](https://github.com/ocharles/weeder/pull/99)).
+- Allow `optparse-applicative-0.17` ([#100](https://github.com/ocharles/weeder/pull/100)).
+
+## [`2.3.0`][v2.3.0] - *2021-10-11*
+
+- Switch to GHC 9
+
+## [`2.2.0`][v2.2.0] - *2021-08-28*
+
+This will likely be the last Weeder release before GHC 9.
+
+- Allow configuration of the HIE file extension using the `--hie-extension` command-line flag
+- Add `--require-hs-files` switch. If supplied, this switch means Weeder will only consider `.hie` files where a corresponding `.hs` file can be found. ([#50](https://github.com/ocharles/weeder/pull/50))
+- Pattern synonyms are now considered ([#79](https://github.com/ocharles/weeder/pull/79))
+- Weeder's output format is now one-line-per-weed ([#62](https://github.com/ocharles/weeder/pull/62))
+- `--hie-extension` can be used to change the extension used for `.hie` files ([#64](https://github.com/ocharles/weeder/pull/64))
+
+## [`2.1.3`][v2.1.3] - *2020-12-11*
+
+- Support `dhall-1.35`, `dhall-1.36` and `dhall-1.37`.
+- Support `bytestring-0.11`.
+
+## [`2.1.2`][v2.1.2] - *2020-09-09*
+
+- Correctly support optparse-applicative 0.16.0.0. While this was meant to be resolved 2.1.1, 2.1.1 only changed the version for the library and not the executable.
+
+## [`2.1.1`][v2.1.1] - *2020-09-09*
+
+- Support Dhall 1.34
+- Support optparse-applicative 0.16.0.0
+
+## [`2.1.0`][v2.1.0] - *2020-06-30*
+
+- Support regex-tdfa ^>= 1.2 (#13)
+- Handle mismatched hie file version explicitly (fixes #8). (#16)
+- Implement --help and --version (#36)
+- Make search directory configurable (#37)
+- Support GHC 8.10
+
+## [`2.0.1`][v2.0.1] - *2020-03-15*
+
+- PR #7: Support optparse-applicative-0.15.1.0 and algebraic-graphs-0.5. Thanks
+  to @robx for contribuiting this fix!
+
+
+## [`2.0.0`][v2.0.0] - *2020-03-15*
+
+- Weeder 2.0 is a ground up rewrite of Weeder using `.hie` files. It is now
+maintained by Ollie Charles (@ocharles on GitHub).
