Update libraries to official release versions

This commit resolves a build error related to mismatched JVM target
versions for the Kotlin and Java compile tasks. Previously, the
'compileJava' task was targeting JVM 11, while the 'compileKotlin'
task was targeting JVM 8.

Both tasks have now been set to target JVM 11, ensuring consistency
and eliminating the build error.

 ## Create a new minor release
+## Bumping BDK Rust Version
+1. - [ ] Open a PR with an update to `Cargo.toml` to the new bdk release candidate and ensure all CI workflows run correctly. Fix errors if necessary.
+2. - [ ] Once the new bdk release is out, update the PR to replace the release candidate with the full release and merge.
 
-### Summary
+### Specific Libraries' Workflows
+#### _Android_
+3. - [ ] Update the API docs to reflect the changes in the API
+4. - [ ] Delete the `target` directory in bdk-ffi and all previous artifacts to make sure you're building the library from scratch.
+5. - [ ] Build the library and run the tests, and adjust if necessary.
+```sh
+# start an emulator prior to running the tests
+cd ./bdk-android/
+./gradlew buildAndroidLib
+./gradlew connectedAndroidTest
+```

-
-### Checklist
-
-Release numbering must follow [Semantic Versioning]. These steps assume the current `master`
-branch **development** version is *MAJOR.MINOR.0*.
-
-#### On the day of the feature freeze
-
-Change the `master` branch to the next MINOR+1 version:
-
-- [ ] Switch to the `master` branch.
-- [ ] Create a new PR branch called `bump_dev_MAJOR_MINOR+1`, eg. `bump_dev_0_22`.
-- [ ] Bump the `bump_dev_MAJOR_MINOR+1` branch to the next development MINOR+1 version.
-  - Change the `Cargo.toml` version value to `MAJOR.MINOR+1.0`.
-  - The commit message should be "Bump version to MAJOR.MINOR+1.0".
-- [ ] Create PR and merge the `bump_dev_MAJOR_MINOR+1` branch to `master`.
-  - Title PR "Bump version to MAJOR.MINOR+1.0".
-
-Create a new release branch:
-
-- [ ] Double check that your local `master` is up-to-date with the upstream repo.
-- [ ] Create a new branch called `release/MAJOR.MINOR+1` from `master`.
-
-Add a release candidate tag, this is optional and only needed for major `bdk-ffi` changes that 
-require a longer testing cycle: 
-
-- [ ] Bump the `release/MAJOR.MINOR+1` branch to `MAJOR.MINOR+1.0-rc.1` version.
-  - Change the `Cargo.toml` version value to `MAJOR.MINOR+1.0-rc.1`.
-  - The commit message should be "Bump version to MAJOR.MINOR+1.0-rc.1".
-- [ ] Add a tag to the `HEAD` commit in the `release/MAJOR.MINOR+1` branch.
-  - The tag name should be `vMAJOR.MINOR+1.0-rc.1`
-  - Use message "Release MAJOR.MINOR+1.0 rc.1".
-  - Make sure the tag is signed, for extra safety use the explicit `--sign` flag.
-- [ ] Push the `release/MAJOR.MINOR` branch and new tag to the `bitcoindevkit/bdk` repo.
-  - Use `git push --tags` option to push the new `vMAJOR.MINOR+1.0-rc.1` tag.
-
-If any issues need to be fixed before the *MAJOR.MINOR+1.0* version is released:
-
-- [ ] Merge fix PRs to the `master` branch.
-- [ ] Git cherry-pick fix commits to the `release/MAJOR.MINOR+1` branch.
-- [ ] Verify fixes in `release/MAJOR.MINOR+1` branch.
-- [ ] Bump the `release/MAJOR.MINOR+1` branch to `MAJOR.MINOR+1.0-rc.x+1` version.
-  - Change the `Cargo.toml` version value to `MAJOR.MINOR+1.0-rc.x+1`.
-  - The commit message should be "Bump version to MAJOR.MINOR+1.0-rc.x+1".
-- [ ] Add a tag to the `HEAD` commit in the `release/MAJOR.MINOR+1` branch.
-  - The tag name should be `vMAJOR.MINOR+1.0-rc.x+1`, where x is the current release candidate number.
-  - Use tag message "Release MAJOR.MINOR+1.0 rc.x+1".
-  - Make sure the tag is signed, for extra safety use the explicit `--sign` flag.
-- [ ] Push the new tag to the `bitcoindevkit/bdk` repo.
-  - Use `git push --tags` option to push the new `vMAJOR.MINOR+1.0-rc.x+1` tag.
-
-#### On the day of the release
-
-Tag and publish new release:
-
-- [ ] Bump the `release/MAJOR.MINOR+1` branch to `MAJOR.MINOR+1.0` version.
-  - Change the `Cargo.toml` version value to `MAJOR.MINOR+1.0`.
-  - The commit message should be "Bump version to MAJOR.MINOR+1.0".
-- [ ] Add a tag to the `HEAD` commit in the `release/MAJOR.MINOR+1` branch.
-  - The tag name should be `vMAJOR.MINOR+1.0`
-  - The first line of the tag message should be "Release MAJOR.MINOR+1.0".
-  - In the body of the tag message put a copy of the **Summary** and **Changelog** for the release.
-  - Make sure the tag is signed, for extra safety use the explicit `--sign` flag.
-- [ ] Wait for the CI to finish one last time.
-- [ ] Push the new tag to the `bitcoindevkit/bdk` repo.
-- [ ] Create the release on GitHub.
-  - Go to "tags", click on the dots on the right and select "Create Release".
-  - Set the title to `Release MAJOR.MINOR+1.0`.
-  - In the release notes body put the **Summary** and **Changelog**.
-  - Use the "+ Auto-generate release notes" button to add details from included PRs.
-  - Until we reach a `1.0.0` release check the "Pre-release" box.
-- [ ] After downstream language repos are also updated announce the release, using the **Summary**,  
-      on Discord, Twitter and Mastodon.
-- [ ] Celebrate 🎉

+### Release Workflow
+17. - [ ] Update the Android, JVM, Python, and Swift libraries as per the _Specific Libraries' Workflows_ section above. Open a single PR on master for all of these changes called `Prepare language bindings libraries for 0.X release`. See [example PR here](https://github.com/bitcoindevkit/bdk-ffi/pull/315).
+- [ ] Create a new branch off of `master` called `release/version`
+18. - [ ] Open a PR to that branch to update the Android, JVM, and Python libraries' versions. See [example PR here](https://github.com/bitcoindevkit/bdk-ffi/pull/316).
+    - [ ] Update bdk-android version from `SNAPSHOT` version to release version
+    - [ ] Update bdk-jvm version from `SNAPSHOT` version to release version
+    - [ ] Update bdk-python version from `.dev` version to release version
+19. - [ ] Merge the PR updating all the languages to their release versions
+20. - [ ] Create the tag and make sure to add the changelog info to the tag (works better if you prepare the tag message on the side in a text editor) and push it to GitHub.
+```sh
+git tag v0.6.0 --sign --edit
+git push upstream v0.6.0
+```
+21. - [ ] Aggregate all the changelog notices from the PRs and add them to the changelog file
+22. - [ ] Open a PR on master with the changes to the changelog file and the development versions bump. See [example PR here](https://github.com/bitcoindevkit/bdk-ffi/pull/317).
+23. - [ ] Make release on GitHub (set as pre-release and generate auto release notes between the previous tag and the new one)
+24. - [ ] Trigger manual releases for all 4 libraries (for Swift, simply add the version number in the text field when running the workflow manually. Note that the version number must not contain the `v`, i.e. `0.26.0`)
+25. - [ ] Bump the versions on master from `0.9.0-SNAPSHOT` to `0.10.0-SNAPSHOT`, `0.6.0.dev0` to `0.7.0.dev0`
+26. - [ ] Build and publish API docs for JVM, Android, and Java on the website
+```bash!
+./gradlew dokkaHtml    # bdk-jvm (Dokka)
+./gradlew dokkaJavadoc # bdk-jvm (java-style documentation)
+./gradlew dokkaHtml    # bdk-android (Dokka)
+```
+27. - [ ] Tweet about the library
+28. - [ ] Post in the announcement channel

 ## How to build
 _Note that Kotlin version `1.6.10` or later is required to build the library._
-
-1. Clone this repository.
+1. Install JDK 11. It must be version 11 (not 17), otherwise it won't build. For example, with SDKMAN!:
+```shell
+curl -s "https://get.sdkman.io" | bash
+source "$HOME/.sdkman/bin/sdkman-init.sh"
+sdk install java 11.0.19-tem
+```
+2. Install Rust (note that we are currently building using Rust 1.67.0):
+```shell
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+rustup default 1.67.0
+```
+3. Clone this repository.
 ```shell
 git clone https://github.com/bitcoindevkit/bdk-ffi
 ```
-2. Follow the "General" bdk-ffi ["Getting Started (Developer)"] instructions.
-3. If building on macOS install required intel and m1 jvm targets
+4. If building on macOS install required intel and m1 jvm targets
 ```sh
 rustup target add x86_64-apple-darwin aarch64-apple-darwin
 ```
-4. Build kotlin bindings
- ```sh
- # build JVM library
- ./gradlew buildJvmLib
- ```
+5. Build kotlin bindings
+```sh
+./gradlew buildJvmLib
+```
