 ## Unreleased
 
 ### Added
-- Added support for OpenQASM 3 `end;` statements. Unrolling stops after an unconditional `end;` in global or nested scopes and keeps `end;` inside runtime-dependent branches. ([#396](https://github.com/qBraid/pyqasm/issues/396))
 
 ### Improved / Modified

 ### Removed
 
 ### Fixed
-- Fixed bare OpenQASM expression statements raising `AttributeError` or `KeyError`. Their values are now evaluated and discarded, and unknown gate errors name the gate using the original source line. ([#388](https://github.com/qBraid/pyqasm/issues/388))
-- Fixed qubit register ranges dropping their final qubit during unrolling. Endpoints are now inclusive for gates, aliases, barriers, and measurements. Code using an exclusive upper bound must lower it by one, for example `q[0:1]` instead of `q[0:2]` to select two qubits. ([#432](https://github.com/qBraid/pyqasm/issues/432))
-- Fixed `cs` and `csdg` from `stdgates.inc` being rejected during unrolling. They now decompose to controlled phase shifts. ([#439](https://github.com/qBraid/pyqasm/issues/439))
-- Fixed Clifford+T rebasing for exact `rx`, `ry`, and `rz` rotations at multiples of π/4. These gates now decompose instead of disappearing, while angles outside the exact basis raise `RebaseError` instead of producing an incorrect result. ([#428](https://github.com/qBraid/pyqasm/issues/428))
-- Fixed the OpenQASM 2 serializer emitting OpenQASM 3 syntax for classical conditionals. `if(m==1) x q[1];` was written as a braced block and, after `unroll()`, as a per-bit `if (m[0] == true)` chain, which QASM 2 parsers such as pytket and Qiskit reject. Conditionals are now emitted as `if (creg == int) <statement>`, and `validate()` rejects branch shapes QASM 2 cannot express. ([#337](https://github.com/qBraid/pyqasm/issues/337))
-- Fixed `unroll()` reading `c[0]` as the most significant bit of a classical register condition, so `if (c == 2)` ran its body when `c` was 1. `>=`, `<=`, `>`, `<`, out-of-range values, and single-bit conditions such as `c[0] < 1` now unroll correctly too, and `!=` is now supported. ([#444](https://github.com/qBraid/pyqasm/pull/444))
 
 ### Dependencies
-- Bumped `codecov/codecov-action` from 7.0.0 to 7.1.1. ([#430](https://github.com/qBraid/pyqasm/pull/430))
-- Bumped `actions/checkout` from 7.0.0 and 4.4.0 (in `scorecard.yml`) to 7.0.1. ([#423](https://github.com/qBraid/pyqasm/pull/423))
 
 ### Other
-- Added a `notify-docs` job to the release workflow. When a release reaches PyPI it sends a `package-released` event to `qBraid/docs`, which opens a pull request bumping its `versions.json` so this release's documentation moves from Latest into Stable. The job reads the published version from PyPI rather than the release tag, runs with `continue-on-error`, and skips when `DOCS_DISPATCH_TOKEN` is absent, so it can never fail or block a release. ([#443](https://github.com/qBraid/pyqasm/pull/443))
