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

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

Modified

Support Message Counts API

v2.7.0

February 19, 2019

Modified

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)

Modified

Publish can now be done via POST

Fixed

Several smaller DNS en/de/coding issues fixed

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.

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

Removed (unused) option to ignore TLS/SSL errors
