-## Writing a plugin ##
-
-New features (backends, commands) can also be added "out-of-tree", through Go plugins.
-Changes will be kept in a dynamically loaded file instead of being compiled into the main binary.
-This is useful if you can't merge your changes upstream or don't want to maintain a fork of rclone.
-
-Usage
-
- - Naming
-   - Plugins names must have the pattern `librcloneplugin_KIND_NAME.so`.
-   - `KIND` should be one of `backend`, `command` or `bundle`.
-   - Example: A plugin with backend support for PiFS would be called
-     `librcloneplugin_backend_pifs.so`.
- - Loading
-   - Supported on macOS & Linux as of now. ([Go issue for Windows support](https://github.com/golang/go/issues/19282))
-   - Supported on rclone v1.50 or greater.
-   - All plugins in the folder specified by variable `$RCLONE_PLUGIN_PATH` are loaded.
-   - If this variable doesn't exist, plugin support is disabled.
-   - Plugins must be compiled against the exact version of rclone to work.
-     (The rclone used during building the plugin must be the same as the source of rclone)
-     
-Building
-
-To turn your existing additions into a Go plugin, move them to an external repository
-and change the top-level package name to `main`.
-
-Check `rclone --version` and make sure that the plugin's rclone dependency and host Go version match.
-
-Then, run `go build -buildmode=plugin -o PLUGIN_NAME.so .` to build the plugin.

 ## Making a point release
 
 If rclone needs a point release due to some horrendous bug:
 
-Set vars
-
-  * BASE_TAG=v1.XX          # eg v1.52
-  * NEW_TAG=${BASE_TAG}.Y   # eg v1.52.1
-  * echo $BASE_TAG $NEW_TAG # v1.52 v1.52.1
-
 First make the release branch.  If this is a second point release then
 this will be done already.
 
-  * git branch ${BASE_TAG} ${BASE_TAG}-stable
-  * git co ${BASE_TAG}-stable
-  * make startstable
+  * BASE_TAG=v1.XX          # eg v1.49
+  * NEW_TAG=${BASE_TAG}.Y   # eg v1.49.1
+  * echo $BASE_TAG $NEW_TAG # v1.49 v1.49.1
+  * git branch ${BASE_TAG} ${BASE_TAG}-fixes
 
 Now
 
-  * git co ${BASE_TAG}-stable
+  * git co ${BASE_TAG}-fixes
   * git cherry-pick any fixes
-  * Do the steps as above
-  * make startstable
-  * NB this overwrites the current beta so we need to do this - FIXME is this true any more?
+  * Test (see above)
+  * make NEW_TAG=v1.XX.1 tag
+  * edit docs/content/changelog.md
+  * make TAG=${NEW_TAG} doc
+  * git commit -a -v -m "Version ${NEW_TAG}"
+  * git tag -d ${NEW_TAG}
+  * git tag -s -m "Version ${NEW_TAG}" ${NEW_TAG}
+  * git push --tags -u origin ${BASE_TAG}-fixes
+  * Wait for builds to complete
+  * make BRANCH_PATH= TAG=${NEW_TAG} fetch_binaries
+  * make TAG=${NEW_TAG} tarball
+  * make TAG=${NEW_TAG} sign_upload
+  * make TAG=${NEW_TAG} check_sign
+  * make TAG=${NEW_TAG} upload
+  * make TAG=${NEW_TAG} upload_website
+  * make TAG=${NEW_TAG} upload_github
+  * NB this overwrites the current beta so we need to do this
   * git co master
-  * # cherry pick the changes to the changelog
-  * git checkout ${BASE_TAG}-stable docs/content/changelog.md
-  * git commit -a -v -m "Changelog updates from Version ${NEW_TAG}"
+  * make LAST_TAG=${NEW_TAG} startdev
+  * # cherry pick the changes to the changelog and VERSION
+  * git checkout ${BASE_TAG}-fixes VERSION docs/content/changelog.md
+  * git commit --amend
   * git push
+  * Announce!
