Fixed

• URL encode channel name(s)

v2.6.3

January 8, 2019

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

v2.6.1

December 2, 2018

Fixed

• Publish via POST encrypted could publish garbage and fail

Fixed

• Several smaller DNS en/de/coding issues fixed

v2.5.8

November 8, 2018

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
