+## 1.1.1
+
+* Require Dart `^3.1.0`
+* Move to `dart-lang/core` monorepo.
+
+## 1.1.0
+
+* Add `tryParseRadix`, `tryParseInt` and `tryParseHex` static methods
+  to both `Int32` and `Int64`.
+* Document exception and overflow behavior of parse functions,
+  and of `toHexString`.
+* Make `Int32` parse functions consistent with documentation (accept
+  leading minus sign, do not accept empty inputs).
+* Update the minimum SDK constraint to 2.19.
+* Update to package:lints 2.0.0.
+
+## 1.0.1
+
+* Switch to using `package:lints`.
+* Populate the pubspec `repository` field.
+
+## 1.0.0
+
+* Stable null safety release.
+
+## 1.0.0-nullsafety.0
+
+* Migrate to null safety.
+  * This is meant to be mostly non-breaking, for opted in users runtime errors
+    will be promoted to static errors. For non-opted in users the runtime
+    errors are still present in their original form.
+
+## 0.10.11
+
+* Update minimum SDK constraint to version 2.1.1.
+
+## 0.10.10
+
+* Fix `Int64` parsing to throw `FormatException` on an empty string or single
+  minus sign. Previous incorrect behaviour was to throw a `RangeError` or
+  silently return zero.
+
+## 0.10.9
+
+* Add `Int64.toStringUnsigned()` and `Int64.toRadixStringUnsigned()` functions.
+
+## 0.10.8
+
+* Set SDK version constraint to `>=2.0.0-dev.65 <3.0.0`.
+
+## 0.10.7
+
+* Bug fix: Make bit shifts work at bitwidth boundaries. Previously,
+  `new Int64(3) << 64 == Int64(3)`. This ensures that the result is 0 in such
+  cases.
+* Updated maximum SDK constraint from 2.0.0-dev.infinity to 2.0.0.
+
+## 0.10.6
+
+* Fix `Int64([int value])` constructor to avoid rounding error on intermediate
+  results for large negative inputs when compiled to JavaScript. `new
+  Int64(-1000000000000000000)` used to produce the same value as
+  `Int64.parseInt("-1000000000000000001")`
+
+## 0.10.5
+
+* Fix strong mode warning in overridden `compareTo()` methods.
+
+*No changelog entries for previous versions...*
