New features:
-------------
 - Added `mdbx_env_set_option()` and `mdbx_env_get_option()` for controls
   various runtime options for an environment (announce of this feature  was missed in a previous news).
 - Added `MDBX_DISABLE_PAGECHECKS` build option to disable some checks to reduce an overhead
   and detection probability of database corruption to a values closer to the LMDB.
   The `MDBX_DISABLE_PAGECHECKS=1` provides a performance boost of about 10% in CRUD scenarios,
   and conjointly with the `MDBX_ENV_CHECKPID=0` and `MDBX_TXN_CHECKOWNER=0` options can yield
   up to 30% more performance compared to LMDB.
 - Using float point (exponential quantized) representation for internal 16-bit values
   of grow step and shrink threshold when huge ones (https://github.com/erthink/libmdbx/issues/166).
   To minimize the impact on compatibility, only the odd values inside the upper half
   of the range (i.e. 32769..65533) are used for the new representation.
 - Added the `mdbx_drop` similar to LMDB command-line tool to purge or delete (sub)database(s).
 - [Ruby bindings](https://rubygems.org/gems/mdbx/) is available now by [Mahlon E. Smith](https://github.com/mahlonsmith).
 - Added `MDBX_ENABLE_MADVISE` build option which controls the use of POSIX `madvise()` hints and friends.
 - The internal node sizes were refined, resulting in a reduction in large/overflow pages in some use cases
   and a slight increase in limits for a keys size to ≈½ of page size.
 - Added to `mdbx_chk` output number of keys/items on pages.
 - Added explicit `install-strip` and `install-no-strip` targets to the `Makefile` (https://github.com/erthink/libmdbx/pull/180).
 - Major rework page splitting (af9b7b5605) for
     - An "auto-appending" feature upon insertion for both ascending and
       descending key sequences. As a result, the optimality of page filling
       increases significantly (more densely, less slackness) while
       inserting ordered sequences of keys,
     - A "splitting at middle" to make page tree more balanced on average.
 - Added `mdbx_get_sysraminfo()` to the API.
 - Added guessing a reasonable maximum DB size for the default upper limit of geometry (https://github.com/erthink/libmdbx/issues/183).
 - Major rework internal labeling of a dirty pages (958fd5b947) for
   a "transparent spilling" feature with the gist to make a dirty pages
   be ready to spilling (writing to a disk) without further altering ones.
   Thus in the `MDBX_WRITEMAP` mode the OS kernel able to oust dirty pages
   to DB file without further penalty during transaction commit.
   As a result, page swapping and I/O could be significantly reduced during extra large transactions and/or lack of memory.
 - Minimized reading leaf-pages during dropping subDB(s) and nested trees.
 - Major rework a spilling of dirty pages to support [LRU](https://en.wikipedia.org/wiki/Cache_replacement_policies#Least_recently_used_(LRU))
   policy and prioritization for a large/overflow pages.
 - Statistics of page operations (split, merge, copy, spill, etc) now available through `mdbx_env_info_ex()`.
 - Auto-setup limit for length of dirty pages list (`MDBX_opt_txn_dp_limit` option).
 - Support `make options` to list available build options.
 - Support `make help` to list available make targets.
 - Silently `make`'s build by default.
 - Preliminary [Python bindings](https://github.com/Thermi/libmdbx/tree/python-bindings) is available now
   by [Noel Kuntze](https://github.com/Thermi) (https://github.com/erthink/libmdbx/issues/147).

Backward compatibility break:
-----------------------------
 - The `MDBX_AVOID_CRT` build option was renamed to `MDBX_WITHOUT_MSVC_CRT`.
   This option is only relevant when building for Windows.
 - The `mdbx_env_stat()` always, and `mdbx_env_stat_ex()` when called with the zeroed transaction parameter,
   now internally start temporary read transaction and thus may returns `MDBX_BAD_RSLOT` error.
   So, just never use deprecated `mdbx_env_stat()' and call `mdbx_env_stat_ex()` with transaction parameter.
 - The build option `MDBX_CONFIG_MANUAL_TLS_CALLBACK` was removed and now just a non-zero value of
   the `MDBX_MANUAL_MODULE_HANDLER` macro indicates the requirement to manually call `mdbx_module_handler()`
   when loading libraries and applications uses statically linked libmdbx on an obsolete Windows versions.

Fixes:
------
 - Fixed performance regression due non-optimal C11 atomics usage (https://github.com/erthink/libmdbx/issues/160).
 - Fixed "reincarnation" of subDB after it deletion (https://github.com/erthink/libmdbx/issues/168).
 - Fixed (disallowing) implicit subDB deletion via operations on `@MAIN`'s DBI-handle.
 - Fixed a crash of `mdbx_env_info_ex()` in case of a call for a non-open environment (https://github.com/erthink/libmdbx/issues/171).
 - Fixed the selecting/adjustment values inside `mdbx_env_set_geometry()` for implicit out-of-range cases (https://github.com/erthink/libmdbx/issues/170).
 - Fixed `mdbx_env_set_option()` for set initial and limit size of dirty page list ((https://github.com/erthink/libmdbx/issues/179).
 - Fixed an unreasonably huge default upper limit for DB geometry (https://github.com/erthink/libmdbx/issues/183).
 - Fixed `constexpr` specifier for the `slice::invalid()`.
 - Fixed (no)readahead auto-handling (https://github.com/erthink/libmdbx/issues/164).
 - Fixed non-alloy build for Windows.
 - Switched to using Heap-functions instead of LocalAlloc/LocalFree on Windows.
 - Fixed `mdbx_env_stat_ex()` to returning statistics of the whole environment instead of MainDB only (https://github.com/erthink/libmdbx/issues/190).
 - Fixed building by GCC 4.8.5 (added workaround for a preprocessor's bug).
 - Fixed building C++ part for iOS <= 13.0 (unavailability of  `std::filesystem::path`).
 - Fixed building for Windows target versions prior to Windows Vista (`WIN32_WINNT < 0x0600`).
 - Fixed building by MinGW for Windows (https://github.com/erthink/libmdbx/issues/155).

TODO for a next releases:
-------------------------
 - [Get rid of dirty-pages list in MDBX_WRITEMAP mode](https://github.com/erthink/libmdbx/issues/193).
 - [Large/Overflow pages accounting for dirty-room](https://github.com/erthink/libmdbx/issues/192).
 - [C++ Buffer issue](https://github.com/erthink/libmdbx/issues/191).
 - Finalize C++ API (few typos and trivia bugs are still likely for now).
 - [Support for RAW devices](https://github.com/erthink/libmdbx/issues/124).
 - [Test framework issue](https://github.com/erthink/libmdbx/issues/127).
 - [Support MessagePack for Keys & Values](https://github.com/erthink/libmdbx/issues/115).
 - [Engage new terminology](https://github.com/erthink/libmdbx/issues/137).
 - Packages for [Astra Linux](https://astralinux.ru/), [ALT Linux](https://www.altlinux.org/), [ROSA Linux](https://www.rosalinux.ru/), Fedora/RHEL, Debian/Ubuntu.
