5 <h2 id="p-nacl-deprecation-announcements">(P)NaCl Deprecation Announcements</h2>
6 <p>Given the momentum of cross-browser WebAssembly support, we plan to focus our
7 native code efforts on WebAssembly going forward and plan to remove support for
8 PNaCl in Q1 2018 (except for Chrome Apps). We believe that the vibrant
9 ecosystem around <a class="reference external" href="http://webassembly.org">Web Assembly</a>
10 makes it a better fit for new and existing high-performance
11 web apps and that usage of PNaCl is sufficiently low to warrant deprecation.</p>
12 <p>We also recently announced the deprecation Q1 2018 of
13 <a class="reference external" href="https://blog.chromium.org/2016/08/from-chrom e-apps-to-web.html">Chrome Apps</a>
14 outside of ChromeOS.</p>
15 <h2 id="toolchain-migration">Toolchain Migration</h2>
16 <p>For the majority of (P)NaCl uses cases we recommend transitioning
17 from the NaCl SDK to <a class="reference external" href="http://webassembly.org/ getting-started/developers-guide/">Emscripten</a>.
18 Migration is likely to be reasonably straightforward
19 if your application is portable to Linux, uses
20 <a class="reference external" href="https://www.libsdl.org/">SDL</a>, or POSIX A PIs.
21 While direct support for NaCl / Pepper APIs in not available,
22 we&#8217;ve attempted to list Web API equivalents.
23 For more challenging porting cases, please reach out on
24 <a class="reference external" href="mailto:native-client-discuss&#37;&#52;&#48;g ooglegroups&#46;com">native-client-discuss<span>&#64;</span>googlegroups<span>&# 46;</span>com</a></p>
25 <h2 id="api-migration">API Migration</h2>
26 <p>We&#8217;ve outlined here the status of Web Platform substitutes for each
27 of the APIs exposed to (P)NaCl.
28 Additionally, the table lists the library or option in Emscripten
29 that offers the closest substitute.</p>
30 <p>We expect to add shared memory threads support to WebAssembly in 2017,
31 as threads are crucial to matching (P)NaCl&#8217;s most interesting use
32 cases. Migration items which assume forthcoming threads support
33 are marked below. If your application&#8217;s flow control relies heavily on blo cking
34 APIs, you may also find threads support is required for convenient porting.</p>
35 <p>While we&#8217;ve tried to be accurate in this table,
36 there are no doubt errors or omissions.
37 If you encounter one, please reach out to us on
38 <a class="reference external" href="mailto:native-client-discuss&#37;&#52;&#48;g ooglegroups&#46;com">native-client-discuss<span>&#64;</span>googlegroups<span>&# 46;</span>com</a></p>
