This page contains all the information I've been able to dig up from the internet about the publication history of The Flight of the Heron. It's definitely incomplete, especially regarding recent commercial ebook editions (though those are not terribly interesting; the book is in the public domain in most countries and free public domain ebooks are the only ones really worth considering) and translations into other languages (very interesting! Please tell me about any more you know of).
The Flight of the Heron was first published in October 1925 by William Heinemann Ltd., London[1]. This edition includes a rather lovely map, which seems to have been lost from at least most later editions—see the Geography page for more discussion.
It was reprinted by Heinemann in at least 1925 and 1926; in a Cheap Edition in 1927 twice, 1928 twice, 1929, 1930, 1931, 1932, 1933, 1934, 1936, 1937, 1939, 1940; in a Popular Edition in 1931, 1932, 1933, 1936, 1937, 1939; in a new edition in their young adult New Windmill series in 1943, 1947, 1949, 1951, 1953, 1956, 1958, 1961, 1964, 1968, 1972, 1979[2].
A new edition was published by Penguin under their young adult imprint Peacock Books in 1963; it was reprinted in 1968, 1971 and 1972[3].
A new edition illustrated by Laurence H. Sandy was published by Edito-Service in 1974[4].
An omnibus edition of The Flight of the Heron and its two sequels The Gleam in the North and The Dark Mile was published in 1984 by Penguin under the new title A Jacobite Trilogy[5]. A new edition of this omnibus, with the title slightly altered to The Jacobite Trilogy, was published in 1993 by Reed Consumer Books Ltd. under the Mandarin Paperbacks imprint, and reprinted in 1996[6].
The first American publication was by Dodd, Mead & Co. in 1926[7]; but the book seems to have achieved wider recognition in the USA with the publication of a new edition by Coward McCann in 1930. This edition includes some new maps and some slightly anatomically dodgy heron illustrations, which can be seen here.
An audiobook read by Peter Forbes was published by Creative Content, London in 2021[8].

An ebook version was published on Faded Page in 2020 (the book had been public domain in Canada, with its relatively liberal copyright laws, for longer)[13], based on a 1932 Heinemann edition.
