+## [Unreleased]
+
+## [1.6.3] - 2023-05-18
+
+### Changed
+
+- Based on SQLite version 3.42.0
+- Enabled session extension
+
+### Fixed
+
+- Fixed incorrect patch of SQLite shell source
+
+## [1.6.2] - 2023-03-23
+
+### Changed
+
+- Based on SQLite version 3.41.2
+
+## [1.6.1] - 2023-03-14
+
+### Changed
+
+- Based on SQLite version 3.41.1
+- Symbol `MAX_PATHNAME` (used on Unix-like platforms) has a fixed value of **512** in the original SQLite source code. This can now be configured at compile time to use a higher value (like **4096** - which is supported by most Linux variants) (see issue #104). Use symbol `SQLITE3MC_MAX_PATHNAME` to define a higher value.
+
+## [1.6.0] - 2023-02-23
+
+### Changed
+
+- Based on SQLite version 3.41.0
+- Added CMake build support (thanks to @lwttai and @jammerxd)
+
+### Added
+
+- Added automatic VFS shim instantiation (see issue #104)
+  To enable encryption support for a non-default VFS it is now enough to specify the name of the requested real VFS with the prefix **multipleciphers-**, either via the URI parameter `vfs` or via the 4th parameter of the SQLite API function `sqlite3_open_v2()`.

+
+:warning:️ **Important Information when operating SQLite in WAL journal mode** :warning:️
+
+To allow concurrent use of SQLite databases in WAL journal mode with legacy encryption implementations like [System.Data.SQLite](https://system.data.sqlite.org) or [SQLCipher](https://www.zetetic.net/sqlcipher/) a new WAL journal encryption implementation was introduced in _SQLite Multiple Ciphers version **1.3.0**_. 
+
+Unfortunately, WAL journals left behind by versions <= 1.2.5 are not compatible with this new implementation. To be able to access WAL journals created by prior versions, the configuration parameter `mc_legacy_wal` was introduced. If the parameter is set to 1, then the prior WAL journal encryption mode is used. The default of this parameter can be set at compile time by setting the symbol `SQLITE3MC_LEGACY_WAL` accordingly, but the actual value can also be set at runtime using the pragma or the URI parameter `mc_legacy_wal`.
+
+In principle, operating generally in WAL legacy mode is possible, but it is strongly recommended to use the WAL legacy mode only to recover WAL journals left behind by prior versions without data loss.
+
+### Added
+
+- Added configuration parameter `mc_legacy_wal` (issue #40)
+
+### Fixed
+
+- Issue #39: Corrupted WAL journal due to referencing the wrong codec pointer
+
+## [1.3.1] - 2021-04-28
+
+:stop_sign: **Attention** :stop_sign:
+
+As described in issue #39 using SQLite in _WAL journal mode_ is broken in this version.
+
+### Changed
+
+- Prevent rekey in WAL journal mode, because performing a rekeying operation (`PRAGMA rekey`) in WAL journal mode could cause database corruption.
+
+### Fixed
+
+- Fix issue in user authentication extension that prevented VACUUMing or rekeying
+
+## [1.3.0] - 2021-04-23
+
+:stop_sign: **Attention** :stop_sign:
+
+As described in issue #39 using SQLite in _WAL journal mode_ is broken in this version.
+
+### Changed
+
+- Based on SQLite version 3.35.5
+- Adjusted build files for MinGW
+  The compile option was changed from **-march=native** to **-msse4.2 -maes**. Additionally, the MinGW variant _TDM-GCC_ is now supported by replacing the use of `RtlGenRandom` (aka `SystemFunction036`) with the use of the standard function `rand_s` (which internally calls `RtlGenRandom`). The direct call to `RtlGenRandom` can be activated by defining the compile time symbol `SQLITE3MC_USE_RAND_S=0`.
+
+### Fixed
+
+- Issue #37: Allow concurrent access from legacy applications by establishing WAL journal mode compatibility
+  This change allows concurrent use of applications still using SQLite versions (< 3.32.0) based on the `SQLITE_HAS_CODEC` encryption API and applications using the new _SQLite3 Multiple Ciphers_ implementation in WAL journal mode.
+- Issue #36: Clear pager cache after setting a new passphrase to force a reread of the database header
