+# Upgrade procedure to Gluster 10, from Gluster 9.x, 8.x and 7.x
+
+We recommend reading the [release notes for 10.0](../release-notes/10.0.md) to be
+aware of the features and fixes provided with the release.
+
+> **NOTE:** Before following the generic upgrade procedure checkout the "**Major Issues**" section given below.
+
+Refer, to the [generic upgrade procedure](./generic-upgrade-procedure.md) guide and follow documented instructions.
+
+## Major issues
+
+### The following options are removed from the code base and require to be unset
+before an upgrade from releases older than release 4.1.0,
+
+    - features.lock-heal
+    - features.grace-timeout
+
+To check if these options are set use,
+
+```console
+# gluster volume info
+```
+
+and ensure that the above options are not part of the `Options Reconfigured:`
+section in the output of all volumes in the cluster.
+
+If these are set, then unset them using the following commands,
+
+```console
+# gluster volume reset <volname> <option>
+```
+
+### Make sure you are not using any of the following depricated features :
+
+    - Block device (bd) xlator
+    - Decompounder feature
+    - Crypt xlator
+    - Symlink-cache xlator
+    - Stripe feature
+    - Tiering support (tier xlator and changetimerecorder)
+    - Glupy
+
+
+**NOTE:** Failure to do the above may result in failure during online upgrades,
+and the reset of these options to their defaults needs to be done **prior** to
+upgrading the cluster.
+
+### Deprecated translators and upgrade procedure for volumes using these features
+
+[If you are upgrading from a release prior to release-6 be aware of deprecated xlators and functionality](https://docs.gluster.org/en/latest/Upgrade-Guide/upgrade_to_6/#deprecated-translators-and-upgrade-procedure-for-volumes-using-these-features).

+# Release notes for Gluster 10.0
+
+This is a major release that includes a range of features, code improvements and stability fixes as noted below.
+
+A selection of the key features and changes are documented in this page.
+A full list of bugs that have been addressed is included further below.
+
+- [Announcements](#announcements)
+- [Highlights](#highlights)
+- [Bugs addressed in the release](#bugs-addressed)
+
+## Announcements
+
+1. Releases that receive maintenance updates post release 10 is 9
+([reference](https://www.gluster.org/release-schedule/))
+2. Release 10 will receive maintenance updates around the 15th of every alternative month, and the release 9 will recieve maintainance updates around 15th every three months. 
+
+
+
+
+## Highlights
+
+- Major performance improvement of ~20% w.r.t small files
+  as well as large files testing in controlled lab environments [#2771](https://github.com/gluster/glusterfs/issues/2771)
+ 
+  **NOTE**: The above improvement requires tcmalloc library to be enabled for building.  We have tested and verified tcmalloc in X86_64 platforms and is enabled   only for x86_64 builds in current release. 
+  
+- Randomized port selection for bricks, improves startup time [#786](https://github.com/gluster/glusterfs/issues/786)
+- Performance improvement with use of readdir instead of readdirp in fix-layout [#2241](https://github.com/gluster/glusterfs/issues/2241)
+- Heal time improvement with bigger window size [#2067](https://github.com/gluster/glusterfs/issues/2067)
