Version Numbers and Releases
|
|
|
|
Curl is not only curl. Curl is also libcurl. They're actually individually
|
|
versioned, but they mostly follow each other rather closely.
|
|
|
|
The version numbering is always built up using the same system:
|
|
|
|
X.Y[.Z][-preN]
|
|
|
|
Where
|
|
X is main version number
|
|
Y is release number
|
|
Z is patch number
|
|
N is pre-release number
|
|
|
|
One of these numbers will get bumped in each new release. The numbers to the
|
|
right of a bumped number will be reset to zero. If Z is zero, it may not be
|
|
included in the version number. The pre release number is only included in
|
|
pre releases (they're never used in public, official, releases).
|
|
|
|
The main version number will get bumped when *really* big, world colliding
|
|
changes are made. The release number is bumped when big changes are
|
|
performed. The patch number is bumped when the changes are mere bugfixes and
|
|
only minor feature changes. The pre-release is a counter, to identify which
|
|
pre-release a certain release is.
|
|
|
|
When reaching the end of a pre-release period, the version without the
|
|
pre-release part will be released as a public release.
|
|
|
|
It means that after release 1.2.3, we can release 2.0 if something really big
|
|
has been made, 1.3 if not that big changes were made or 1.2.4 if mostly bugs
|
|
were fixed. Before 1.2.4 is released, we might release a 1.2.4-pre1 release
|
|
for the brave people to try before the actual release.
|
|
|
|
Bumping, as in increasing the number with 1, is unconditionally only
|
|
affecting one of the numbers (except the ones to the right of it, that may be
|
|
set to zero). 1 becomes 2, 3 becomes 4, 9 becomes 10, 88 becomes 89 and 99
|
|
becomes 100. So, after 1.2.9 comes 1.2.10. After 3.99.3, 3.100 might come.
|
|
|
|
All original curl source release archives are named according to the libcurl
|
|
version (not according to the curl client version that, as said before, might
|
|
differ).
|
|
|
|
As a service to any application that might want to support new libcurl
|
|
features while still being able to build with older versions, all releases
|
|
have the libcurl version stored in the curl/curlver.h file using a static
|
|
numbering scheme that can be used for comparison. The version number is
|
|
defined as:
|
|
|
|
#define LIBCURL_VERSION_NUM 0xXXYYZZ
|
|
|
|
Where XX, YY and ZZ are the main version, release and patch numbers in
|
|
hexadecimal. All three numbers are always represented using two digits. 1.2
|
|
would appear as "0x010200" while version 9.11.7 appears as "0x090b07".
|
|
|
|
This 6-digit hexadecimal number does not show pre-release number, and it is
|
|
always a greater number in a more recent release. It makes comparisons with
|
|
greater than and less than work.
|
|
|
|
This number is also available as three separate defines:
|
|
LIBCURL_VERSION_MAJOR, LIBCURL_VERSION_MINOR and LIBCURL_VERSION_PATCH.
