-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [adding m4-discuss] According to Bruno Haible on 2/26/2008 4:35 AM: | Hi Eric, | |> The GNU M4 team is pleased to announce the beta release of M4 1.4.10b. |> This release features a rewrite of the parsing engine, such that recursive |> macro expansions that used to scale quadratically in both memory in time |> are now linear in memory and time. | | Effects on "autoconf" in gettext/gettext-tools: | | m4-1.4.10 50.6 s real + 1.0 sec system | m4-1.4.10b 42.1 s real + 0.9 sec system Similar improvements to what I measured on coreutils, during my 5-month efforts on getting rid of the quadratic effects. | | Wouldn't this be a reason to call the next release m4-1.5 ? It's not only a | minor improvement. Historically, we intended for m4-1.5 to introduce modules. However, that effort has been stalled for so long (partly because it depends on the release of libtool 2.2), and introduces such a major rewrite of the internals, that a couple years ago we made the decision to rename the head development branch 1.9a, ready to bump to 2.0 once released. Would anyone be confused if I make the next stable release on the branch be 1.5 rather than 1.4.11, even though it means m4-1.5 does not have the historically promised module capabilities? It _is_ a rather large rewrite of the parsing engine, with some impressive speedups. I have actually been thinking about the release numbering, even before Bruno's mail. Also, if I bump the branch to 1.5, I'd like to turn on i18n on the branch. ~ Which means there will have to be at least one more beta release in order to give the translation teams time to work. - -- Don't work too hard, make some time for fun as well!
