== Service Bulletin - Telegram now requires the TLSv1.2 cryptographic protocol, breaking compatibility on Java 6 and Java 7 virtual machines ==
As of Wednesday, Feb. 5, 2020, the Telegram BOT service only accepts connections from clients using version 1.2 of the TLS cryptographic protocol, breaking compatibility of the Telegram HSYCO I/O Server when running on old Java 6 and Java 7 virtual machines.

=== Release Date ===
February 5, 2020

=== Affected Platforms ===
*Any HSYCO Server running on old Java 6 and Java 7 virtual machines

=== Description ===
Because TLSv1.2 is not supported on Java 6 and is not the default TLS version on Java 7, the Telegram I/O Server, when HSYCO is running on Java 6 or Java 7, will fail to connect to the Telegram BOT server.

=== Resolution ===
Upgrade to Java 8, if possible.
