5 <h2 id="p-nacl-deprecation-announcements">(P)NaCl Deprecation Announcements</h2>
6 <p>We recently announced the deprecation of Portable NativeClient
7 as well as the deprecation of
8 <a class="reference external" href="https://blog.chromium.org/2016/08/from-chrom e-apps-to-web.html">Chrome Apps</a>
9 outside of ChromeOS.
10 As a result, in the near future, PNaCl will no longer be supported in Chrome.
11 And NaCl will be supported only in the context of ChromeOS and Extensions.</p>
12 <p>We appreciate the investment you&#8217;ve made bringing native code to the We b
13 with these pioneering solutions, but have now refocused our efforts
14 on the cross browser <a class="reference external" href="http://webassembly.org" >WebAssembly</a> standard
15 in order to bring similar functionality to the Web in general.
16 While WebAssembly currently cannot match all of (P)NaCl&#8217;s capabilities,
17 we are working to expand its capabilities in tandem with other
18 browsers, and believe most use cases will soon be covered.</p>
19 <h2 id="toolchain-migration">Toolchain Migration</h2>
20 <p>For the majority of (P)NaCl uses cases we recommend transitioning
21 from the NaCl SDK to <a class="reference external" href="http://webassembly.org/ getting-started/developers-guide/">Emscripten</a>.
22 While direct support for NaCl / Pepper APIs in not available,
23 we&#8217;ve attempted to list equivalents.
24 Migration is likely to be reasonably straightforward
25 if your application is portable to Linux, uses
26 <a class="reference external" href="https://www.libsdl.org/">SDL</a>, or POSIX A PIs.
27 For more challenging porting cases, please reach out on
28 <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>
29 <h2 id="api-migration">API Migration</h2>
30 <p>We&#8217;ve outlined here the status of Web Platform substitutes for each
31 of the APIs exposed to (P)NaCl.
32 Additionally, the table lists the library or option in Emscripten
33 that offers the closest substitute.</p>
34 <p>We expect to add shared memory threads support to WebAssembly in 2017,
35 as threads are crucial to matching (P)NaCl&#8217;s most interesting use
36 cases. Migration items which assume forthcoming threads support
37 are marked below. If your application&#8217;s flow control relies heavily on blo cking
38 APIs, you may also find threads support is required for convenient porting.</p>
39 <p>While we&#8217;ve tried to be accurate in this table,
40 there are no doubt errors or omissions.
41 If you encounter one, please reach out to us on
42 <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>
