It is only a pre-release version 1 for the user community to go through the book and suggest further modifications, corrections, etc. Many people have contributed to this volume, but notable among them is Dr E Krishnan, an ardent free software and maths education activist who served as the chief editor of the book.
Apart from resolving all problems, including the reported ones, the chapter on boxes has been revised. So, also a new chapter on graphics inclusion has been added as the replacement of the very basic original content about the topic in the floats chapter of previous edition. An exhaustive index has also been added.
A release candidate version 2 is also planned which will happen on the last week of February 2020 with two more chapters added how to write a thesis or dissertation using LaTeX. (ii) typesetting documents with Indic scripts with special reference to Malayalam script. Readers are also requested to contribute to this volume if they can.
