[Edit: rvm has a new command to upgrade-- you likely want to use the answer by andy318]

AFAIK, there is no automatic way to do this at the moment, but something like this enables you to keep your gems:

<pre><code> rvm use 1.9.2-preview1
 rvm gemset export
 rvm install 1.9.2-rc1
 rvm use 1.9.2-rc1
 rvm gemset import
 rvm remove 1.9.2-preview1
</code></pre>

Now, for automating updates, you would have to detect version changes, that is easy, as you can simply use the return value of <code>rvm use 1.9.2</code>. Finding out what the new version is (<code>1.9.2-rc1</code>) is unnecessary, as it is aliased as 1.9.2. The trick is to find the latest installed version of 1.9.2. You could do something like this in a cron job:

<pre><code># make sure you source rvm first
rvm update --head
rvm reload
if [ ! rvm use 1.9.2 ]; then
 for ruby_version in `rvm list strings`; do
 # find the latest version of 1.9.2
 case $ruby_version in
 ruby-1.9.2-*) latest192=$ruby_version;;
 esac
 done
 rvm use $latest192
 rvm gemset export 192.gems
 rvm install 1.9.2
 rvm use 1.9.2
 rvm gemset import 192
 rvm remove $latest192
fi
</code></pre>

Did not try that, but I have similar code in my update script. I also slipped in a <code>gem update</code> and other stuff.

Feel free to visit the #rvm IRC channel on Freenode.

Current rvm version provides an easier way to do this. The 'upgrade' option will migrate gem sets, wrappers and environment files - 

<pre><code>$ rvm upgrade 1.9.2-p136 1.9.2-p180
</code></pre>

To find out if there is a more recent stable version of a ruby implementation for you to upgrade to, first get the latest version of RVM and then enumerate the known versions of Ruby. 

<pre><code>$ rvm get stable
$ rvm list known
</code></pre>

You can compare this the ruby versions installed on your system

<pre><code>$ rvm list rubies
</code></pre>

you can install latest rvm and ruby by :

$ \curl -L <a href="https://get.rvm.io" rel="nofollow">https://get.rvm.io</a> | bash -s stable --ruby

and check all the ruby version with stability

$ rvm list known

can also check details here : <a href="http://www.ruby-lang.org/en/downloads/" rel="nofollow">http://www.ruby-lang.org/en/downloads/</a>

$ rvm install ruby 2.0.0-p247 

Use when you want to download specific version or know this is stable.

I installed RVM with a few versions of Ruby-interpreters some time ago.
How I can to update it, because new versions are already released?

I found only one way: <code>rvm install 1.9.2-rc1 &amp;&amp; rvm remove 1.9.2-preview1</code>, but my gems are lost.
Can I update branches time to time? I haven't found any tips in the documentation.

How do I update Ruby-interpreters with RVM?

解释器

不久前，我在RVM上安装了几个版本的Ruby解释器。我该如何更新它，因为新版本已经发布了？我只找到了一种方法：rvm install 1.9.2-rc1 && rvm remove 1.9.2-preview1，但是我的宝石已经丢失了。我可以时不时地更新分支吗？我在文档中没有找到任何提示。
