 ## Making a point release
 
 If rclone needs a point release due to some horrendous bug:
 
-Set vars
-
-  * BASE_TAG=v1.XX          # e.g. v1.52
-  * NEW_TAG=${BASE_TAG}.Y   # e.g. 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 ${BASE_TAG}-fixes
   * git cherry-pick any fixes
-  * Do the steps as above
-  * make startstable
+  * Test (see above)
+  * make NEXT_VERSION=${NEW_TAG} 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 - check the diff to make sure it is correct
