- Oct 2024 -- Release 3.0.0
- Oct 2024 -- after the 3.0.0 release, move main branch to 4.x (and Java 17) and move tika-pipes to its own module or create a standalone tika-pipes project
- ??? -- start 4.0.0-BETA releases ASAP
- April 2025 (6 months from 3.x release) -- end support for 2.x (and thereby Java 8)
- April 2025 (6 months from Oct 2024 or earlier???) -- release 4.0.0
- Oct 2025 (one year from 3.x release) -- end support for 3.x (and thereby Java 11)
