-## v0.14.0 от 2023-03-13
+## v0.13.4 "Sigma Boy" от 2025-02-14
 
-Технический тэг, отмечающий начало ветки `0.14`
-с новым функционалом и изменением API.
+Поддерживающий выпуск стабильной ветки с исправлением обнаруженных ошибок и устранением недочётов.
 
-Запланированные новые возможности 0.14:
+Благодарности:
 
-1. Ранняя (не-отложенная) очистка GC и рефакторинг обновления GC, самостоятельной видимой для пользователя ценности не имеет, но требуется для последующих пунктов.
-Будет реализовано в 0.14.1.
+ - [Алексею Костюку (aka Keller)](https://t.me/keller18306) за сообщения об ошибках и недочетах.
+ - [Erigon](https://docs.erigon.tech/) за спонсорство.
+ - [Alain Picard](https://github.com/castortech) for support [Java bindings](https://github.com/castortech/mdbxjni) and MacOS universal binaries patch for CMake build scenario.
+ - [Alex Sharov](https://github.com/AskAlexSharov) за сообщение об ошибках и тестирование.
+ - [Виктору Логунову](https://t.me/vl_username) за сообщение об опечатки в имени переменной в Conan-рецепте.
 
-2. Явная дефрагментация БД. В API будет добавлена функция с двумя парами параметров:
- - минимальный (требуемый) объем дефрагментации (уменьшения БД) и минимальное время, которое следует потратить;
- - максимальный (ограничивающий) объем дефрагментации и максимальной время, которое допустимо потратить.
+Новое:
 
-Упрощенно, алгоритмически явная дефрагментация сводиться к сканированию b-tree с формированием списка страниц расположенных близко к концу БД, а затем копирование этих страниц в не-используемые, но расположенные ближе к началу БД.
-Будет реализовано в 0.14.2.
+ - Поддержка MacOS universal binaries при сборке посредством CMake.
 
-3. Нелинейная переработка GC, без остановки переработки мусора на старом MVCC-снимке используемом долгой транзакцией чтения.
+Исправления:
 
-Будет реализовано предположительно в 0.14.3, 0.14.4 или даже в 0.15.x.
-Перенос в 0.15.x оправдан возможностью переноса функционала дефрагментации в stable-ветку, но посмотри как пойдут дела.
+ - Устранён регресс допускающий SIGSEGV в операциях обновления после вытеснения/spilling страниц в больших транзакциях.
+   Ошибка присутствует в выпусках v0.13.1, v0.13.2, v0.13.3 и оставалась незамеченной из-за специфических условий и низкой вероятности проявления.
+   Более подробная информация в описании коммита `a060057e480aa5196c7d5c00ea441c962e3b952d`.
+
+ - Исправлена опечатка в документации в упоминании `mdbx_env_resurrect_after_fork()`.
+
+ - Исправлена опечатка в условном операторе внутри `cursor_touch()`.
+   При переделке курсоров было пропущено отрицание в условии, при оценке количества страниц, которые могут потребоваться для выполнения операции.
+   В текущем понимании ошибка не приводила к каким-либо проблемам, ибо оценка делает по верхней границе с существенным запасом, а в худшем
+   случае это могло приводить к прерыванию транзакции из-за достижения ограничения на кол-во грязных страниц.
+
+ - Корректировка излишне строгого условия в assert-проверке внутри `recalculate_subpage_thresholds()`.
+   Ошибка могла проявляться только в отладочных сборках при выставлении определенной комбинации предельных значений опций `MDBX_opt_subpage_limit`,
+   `MDBX_opt_subpage_room_threshold`, `MDBX_opt_subpage_reserve_prereq`, `MDBX_opt_subpage_reserve_limit`.
+
+ - Исправление опечатки в Conan-рецепте в коде протокольно-отладочного вывода в имени переменной `version_json_pathname`.

+take a long time, and checking readers cannot be performed too often due
+to performance degradation.
+
+This issue will be addressed in MithrlDB and one of libmdbx releases,
+presumably in 2025. To do this, nonlinear GC recycling will be
+implemented, without stopping garbage recycling on the old MVCC snapshot

+After the planned implementation, any long-term reading transaction will
+still keep the used MVCC-snapshot (all the database pages forming it)
+from being recycled, but it will allow all unused MVCC snapshots to be
+recycled, both before and after the readable one. This will eliminate
+one of the main architectural flaws inherited from LMDB and caused the
+growth of a database in proportion to a volume of data changes made
+concurrently with a long-running read transaction.
