v2.10.0

September 23, 2019

Modified

• Introduce Objects API

Fixed

• Fix high history (extended/full) handling of 'reverse' and other boolean parameters

v2.9.4

September 10, 2019

Modified

• Introduce separate connection timer, to control/limit the duration of DNS resolving and connection establishment, which should be much shorter than full transaction timer, which has to be >5 min for subscribe

Fixed

• Fix high CPU load in callback interface when no context, thus socket, is executing a transaction

v2.9.3

September 3, 2019

Modified

• Detect TCP/IP connect timeout in callback mode w/sockets - does not seem to work on Windows
• Add set_proxy_none() to pubnub::context

v2.9.2

August 28, 2019

Fixed

• Proxy admin functions (set, get) were not protected by mutex/monitor, so caused a race condition
• Setting new proxy might have been ignored until the resolved DNS addresses of the previous proxy expire.
• If all resolved addresses on file expire, we would report transaction failure instead of just asking for new ones.

v2.9.1

August 25, 2019

Modified

• Improvements in sockets and DNS error reporting

v2.9.0

August 9, 2019

Modified

• Introduce Signals support
• Support subscribe V2 in C++ & Qt
• Add pubnub_stop() for graceful shutdown when using callback interface

• Use QTime for transaction timer duration

v2.8.3

May 31, 2019

Modified

• Better identification of the platform we run on
• Detect authenticating proxy that works incorrectly

v2.8.2

April 29, 2019

Modified

• Will try other address from (async) DNS response if first one fails
• Will try secondary (async) DNS server if primary doesn't work

v2.8.1

April 29, 2019

Modified

• Update pubnub_allooc_std.c to pubnub_cancel() changes

v2.8.0

March 18, 2019

Modified

• Support Message Counts API

v2.7.0

February 19, 2019

Modified

• Support IPv6 for DNS resolution (mostly for callback interface)

v2.6.4

January 17, 2019

Fixed

• URL encode channel name(s)

v2.6.3

January 8, 2019

Modified

• Update samples to changes in pubnub_cancel() and other interface changes
• Update samples to use time() instead of clock() as clock() can measure CPU-only time instead of real time
• Update Qt functional tests and make them reliable
• UUID is now part of the Pubnub context (instead of a pointer to it). This makes handling its lifetime easier, yet does not incur much memory increase

Fixed

• C++ wrapper and Qt did not have proper multithreading support as they did not protect their data. Now that is fixed.

v2.6.2

December 20, 2018

Fixed

• Fix memory leak regarding OpenSSL

v2.6.1

December 2, 2018

Modified

• Publish can now be GZIPed (if done via POST)

Fixed

• Publish via POST encrypted could publish garbage and fail

v2.6.0

November 20, 2018

Modified

• Publish can now be done via POST

Fixed

• Several smaller DNS en/de/coding issues fixed

v2.5.8

November 8, 2018

Modified

• pubnub_await() in the sync interface now reports PNR_TIMEOUT on, well, (transaction) timeout

v2.5.7

November 4, 2018

Fixed

• DNS en/de/coding could fail on some toolchains because of alignment issues.

v2.5.6

November 2, 2018

Fixed

• TLS connection timeout was prone to errors due to time synchronisation and such.

v2.5.5

November 1, 2018

Fixed

• Fix wrong detection of PNR_TIMEOUT, by reset of TLS connect timer when connection is established.

v2.5.4

October 18, 2018

Fixed

• Fix DNS decoding

v2.5.3

October 16, 2018

Added

• Add support for pubnub_subscribe_v2() w/filter expressions
• pubnub_cancel() returns is it done, or it just started the cancellation
• Code that is only for TLS/SSL ifdef-ed out when not building w/TLS/SSL
• Functional tests for C++ updated and now run on each commit

v2.5.2

September 10, 2018

Added

• pubnub_free() now implies pubnub_cancel()
• pubnub_cancel() will now call pbnc_fsm() in the sync interface. Combined with previous, this makes it possible to call pubnub_free() in sync interface and have it succeed even if transaction is ongoing.

Fixed

• Improved handling of lost connection while in HTTP Keep-Alive

v2.5.1

August 30, 2018

Added

• Removed (unused) option to ignore TLS/SSL errors
