| <p>skiboot-5.4.0-rc3 was released on Wednesday November 2nd 2016. It is the |
| third release candidate of skiboot 5.4, which will become the new stable |
| release of skiboot following the 5.3 release, first released August 2nd 2016.</p> |
| <p>skiboot-5.4.0-rc3 contains all bug fixes as of <a class="reference internal" href="skiboot-5.3.7.html#skiboot-5-3-7"><span class="std std-ref">skiboot-5.3.7</span></a> |
| and <a class="reference internal" href="skiboot-5.1.18.html#skiboot-5-1-18"><span class="std std-ref">skiboot-5.1.18</span></a> (the currently maintained stable releases).</p> |
| <p>For how the skiboot stable releases work, see <a class="reference internal" href="../process/stable-skiboot-rules.html#stable-rules"><span class="std std-ref">Skiboot stable tree rules and releases</span></a> for details.</p> |
| <p>Since this is a release candidate, it should <em>NOT</em> be put into production.</p> |
| <p>The current plan is to release a new release candidate every week until we |
| feel good about it. The aim is for skiboot-5.4.x to be in op-build v1.13, which |
| is due by November 23rd 2016.</p> |
| <p>Over <a class="reference internal" href="skiboot-5.4.0-rc2.html#skiboot-5-4-0-rc2"><span class="std std-ref">skiboot-5.4.0-rc2</span></a>, we have a few changes:</p> |
| <ul class="simple"> |
| <li><p>pflash: Fail when file is larger than partition |
| You can still shoot yourself in the foot by passing –force.</p></li> |
| <li><p>core/flash: Don’t do anything clever for OPAL_FLASH_{READ, WRITE, ERASE} |
| This fixes a bug where opal-prd and opal-gard could fail. |
| Fixes: <a class="reference external" href="https://github.com/open-power/skiboot/issues/44">https://github.com/open-power/skiboot/issues/44</a></p></li> |
| <li><p>boot-tests: force BMC to boot from non-golden side</p></li> |
| <li><p>fast-reset: Send special reset sequence to operational CPUs only. |
| Fixes fast-reset for cases where there are garded CPUs</p></li> |
| <li><p>Secure/Trusted boot: be much clearer about what is being measured where.</p></li> |
| <li><p>Secure/Trusted boot: be more resilient to disabled TPM(s).</p></li> |
| <li><p>Secure/Trusted boot: The <code class="docutils literal notranslate"><span class="pre">force-secure-mode</span></code> NVRAM setting introduced |
| temporarily in <a class="reference internal" href="skiboot-5.4.0-rc2.html#skiboot-5-4-0-rc2"><span class="std std-ref">skiboot-5.4.0-rc2</span></a> has changed behaviour. Now, by |
| default, the <code class="docutils literal notranslate"><span class="pre">secure-mode</span></code> flag in the device tree is obeyed. As always, |
| any skiboot NVRAM options are in no way ABI, API or supported and may cause |
| unfinished verbose analogies to appear in release notes relating to the |
| dangers of using developer only options.</p></li> |
| <li><p>gard: Fix compiler warning on modern GCC targetting ARM 32-bit</p></li> |
| <li><p>opal-prd: systemd scripts improvements, only run on supported systems</p></li> |
