Restore native artifact packaging
Zig cross-compilation produced LMDB libraries 31% slower than distribution packages. This restores the native artifact, now fetching pre-compiled libraries from Arch Linux, Homebrew and MSYS2 instead of compiling them ourselves. This approach reduces complexity and is practical given infrequent LMDB releases.

# LMDB Native Libraries
116

12-
This repository creates standard builds of the [LMDB](http://symas.com/mdb/)
13-
native library. It packages the built libraries into operating system-specific
14-
JARs (with POMs). This allows [LmdbJava](https://github.com/lmdbjava/lmdbjava)
15-
(or other interested Java projects) to depend on these JARs using the normal
16-
Maven dependency resolution process.
17-
18-
**If you are simply wishing to use LMDB from Java, please use the
19-
[LmdbJava](https://github.com/lmdbjava/lmdbjava) project.**
20-
21-
This project is intended to be executed by GitHub Actions, as Linux, Windows and
22-
macOS operating systems are all required. Linux is used for compiling the Linux
23-
modules, whereas Windows and macOS compile their modules.
24-
25-
### Versioning
7+
Provides pre-compiled LMDB native libraries for Linux, macOS and Windows. These libraries are fetched from distribution package managers (Arch Linux, Homebrew, MSYS2) and packaged into a single JAR for easy dependency resolution.
268

27-
This project uses the `major.minor.patch-qualifier` version numbering typical
28-
of Maven projects. The major, minor and patch directly reflect the upstream
29-
LMDB library version, as expressed by `lmdb.h` `MDB_VERSION_*` definitions.
30-
The qualifier resets to `1` on a new major, minor or patch release.
9+
**If you are using LMDB from Java, use the [LmdbJava](https://github.com/lmdbjava/lmdbjava) project instead.** This artifact is a dependency of LmdbJava.

### Repository
11+
Available from [Maven Central](http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22org.lmdbjava%22%20AND%20a%3A%22native%22) and [Central Portal Snapshots](https://central.sonatype.com/repository/maven-snapshots/org/lmdbjava/native).
3312

34-
[LmdbJava](https://github.com/lmdbjava/lmdbjava) shades inside its JAR all of
35-
the system libraries produced by this project. As such, end users typically have
36-
no need to refer to any artifacts produced by this project.
13+
### Version Management
3714

38-
### Snapshots
15+
Update all dependency and plugin versions:
16+
```bash
17+
mvn versions:update-properties
18+
```
3919

40-
GitHub Actions automatically publishes snapshot releases to the
41-
[OSS Sonatype Snapshots Repository](https://oss.sonatype.org/content/repositories/snapshots/org/lmdbjava/lmdbjava-native-parent/).
42-
43-
### Support
44-
45-
Please [open a GitHub issue](https://github.com/lmdbjava/native/issues) if you
46-
have any questions.

Contributions are welcome! Please see the LmdbJava project's
51-
[Contributing Guidelines](https://github.com/lmdbjava/lmdbjava/blob/master/CONTRIBUTING.md).
20+

55-
Please see the [Acegi Standard Project Release Instructions](https://github.com/acegi/acegi-standard-project#performing-a-release).
24+
GitHub Actions will perform an official release whenever a developer executes `mvn release:clean release:prepare`.
