LibreOffice: the current status of the most powerful OSS office suite

LibreOffice: the current status of the most powerful OSS office suite

for HKOSCon2020 https://hkoscon.org/2020/

LibreOffice is a successor of OpenOffice.org and full-featured open-source office software. It is a large application written in 9 million lines of C ++, with an estimated 2 billion users worldwide. It has been known as a desktop application, but for resenting years the "online" version, which allows edit documents via modern web browsers, has also be developed, and mobile versions will also be available soon.

This talk will introduce the current state of both the LibreOffice product and development, such as compatibility improvement with proprietary application document formats, document confidentiality using OpenGPG, improved spreadsheet performance through multi-threading, LibreOffice Online implementation, etc.

And also, it will introduce activities in Asian regions to improve regional-specific features such as CJK rendering.
