CHANGELOG entry copied here:

2015-08-04, Version 3.0.0, @rvagg

Notable changes

buffer:
- Due to changes in V8, it has been necessary to reimplement Buffer on top of V8's Uint8Array. While every effort has been made to maintain performance, users are likely to experience a different performance profile depending on how Buffer is used. (Trevor Norris) #1825.
- Buffer can now take ArrayBuffers as a constructor argument (Trevor Norris) #2002.
- When a single buffer is passed to Buffer.concat(), a new, copied Buffer object will be returned; previous behavior was to return the original Buffer object (Sakthipriyan Vairamani) #1937.
build: PPC support has been added to core to allow compiling on pLinux BE and LE (AIX support coming soon) (Michael Dawson) #2124.
dgram: If an error occurs within socket.send() and a callback has been provided, the error is only passed as the first argument to the callback and not emitted on the socket object; previous behavior was to do both (Matteo Collina & Chris Dickinson) #1796
freelist: Deprecate the undocumented freelist core module (Sakthipriyan Vairamani) #2176.
http:
- Status codes now all use the official IANA names as per RFC7231, e.g. http.STATUS_CODES[414] now returns 'URI Too Long' rather than 'Request-URI Too Large' (jomo) #1470.
- Calling .getName() on an HTTP agent no longer returns a trailing colon, HTTPS agents will no longer return an extra colon near the middle of the string (Brendan Ashworth) #1617.
node:
- NODE_MODULE_VERSION has been bumped to 45 to reflect the break in ABI (Rod Vagg) #2096.
- Introduce a new process.release object that contains a name property set to 'io.js' and sourceUrl, headersUrl and libUrl (Windows only) properties containing URLs for the relevant resources; this is intended to be used by node-gyp (Rod Vagg) #2154.
- The version of node-gyp bundled with io.js now downloads and uses a tarball of header files from iojs.org rather than the full source for compiling native add-ons; it is hoped this is a temporary floating patch and the change will be upstreamed to node-gyp soon (Rod Vagg) #2066.
repl: Persistent history is now enabled by default. The history file is located at ~/.node_repl_history, which can be overridden by the new environment variable NODE_REPL_HISTORY. This deprecates the previous NODE_REPL_HISTORY_FILE variable. Additionally, the format of the file has been changed to plain text to better handle file corruption. (Jeremiah Senkpiel) #2224.
smalloc: The smalloc module has been removed as it is no longer possible to provide the API due to changes in V8 (Ben Noordhuis) #2022.
tls: Add server.getTicketKeys() and server.setTicketKeys() methods for TLS session key rotation (Fedor Indutny) #2227.
v8: Upgraded to 4.4.63.26
- ES6: Enabled computed property names
- ES6: Array can now be subclassed in strict mode
- ES6: Implement rest parameters in staging, use the --harmony-rest-parameters command line flag
- ES6: Implement the spread operator in staging, use the --harmony-spreadcalls command line flag
- Removed SetIndexedPropertiesToExternalArrayData and related APIs, forcing a shift to Buffer to be reimplemented based on Uint8Array
- Introduction of Maybe and MaybeLocal C++ API for objects which may or may not have a value.
- Added support for PPC

Known issues

See https://github.com/nodejs/io.js/labels/confirmed-bug for complete and current list of known issues.

Some problems with unreferenced timers running during beforeExit are still to be resolved. See #1264.
Surrogate pair in REPL can freeze terminal. #690
process.send() is not synchronous as the docs suggest, a regression introduced in 1.0.2, see #760.
Calling dns.setServers() while a DNS query is in progress can cause the process to crash on a failed assertion. #894

Updated known issues to include:

Using multiple REPL instances in parallel may cause some REPL history corruption or loss. #1634

From v3.0.0-alpha, essentially identical to this branch:

https://jenkins-iojs.nodesource.com/job/node-test-commit/103/

From this branch:
https://jenkins-iojs.nodesource.com/job/node-test-commit/104/

Moving forward with release if that comes out green sans known flaky tests

rvagg · 2015-08-04T19:54:51Z

I have this for Buffer now:

Due to changes in V8, it has been necessary to reimplement Buffer on top of V8's Uint8Array. While every effort has been made to minimize the performance impact, users are likely to experience a different performance profile depending on how Buffer is used. (Trevor Norris) #1825.

But it feels a bit too hand-wavy. @trevnorris' current measurements suggests there may be up to a 70% degradation in Buffer instantiation but the actual impact beyond that is uncertain mainly because the uses of Buffer vary so much within core and across applications and instantiation is only one (small) part of this.

If anyone has suggestions for how to convey useful information without making it sound too scary or providing negative-tweet-fodder then I'd love to hear it!

rvagg · 2015-08-04T20:00:09Z

Sorry, "70% degradation" is wrong, more meaningful to say that instantiation is now taking between 150% and 170% in v3 over what it takes with v2.

domenic · 2015-08-04T20:03:12Z

IMO the current text seems good. Instantiation takes longer (usually? sometimes? always?), but access and use is faster for certain sizes IIUC. "Different performance profile" sounds about right. @trevnorris seems like the one you really want to answer though.

trevnorris · 2015-08-04T20:21:38Z

@domenic re Buffer performance difference. I remember it being comparable in v4.3, and even faster as buffers grew larger (less impact on GC), but in v4.4 the performance has drastically decreased. You can even see that using any normal typed array. Not just in Buffer.

rvagg · 2015-08-04T20:28:50Z

Due to changes in V8, it has been necessary to reimplement Buffer on top of V8's Uint8Array. Every effort has been made to minimize the performance impact, however Buffer instantiation is measurably slower. The exact performance profile and difference over previous versions will depend on how Buffer is used within applications.
