1.1       misho       1: Version Numbers and Releases
                      2: ============================
                      3: 
                      4:  Curl is not only curl. Curl is also libcurl. They're actually individually
                      5:  versioned, but they mostly follow each other rather closely.
                      6: 
                      7:  The version numbering is always built up using the same system:
                      8: 
                      9:         X.Y.Z
                     10: 
                     11:   - X is main version number
                     12:   - Y is release number
                     13:   - Z is patch number
                     14: 
                     15: ## Bumping numbers
                     16: 
                     17:  One of these numbers will get bumped in each new release. The numbers to the
                     18:  right of a bumped number will be reset to zero. If Z is zero, it may not be
                     19:  included in the version number.
                     20: 
                     21:  The main version number will get bumped when *really* big, world colliding
                     22:  changes are made. The release number is bumped when changes are performed or
                     23:  things/features are added. The patch number is bumped when the changes are
                     24:  mere bugfixes.
                     25: 
                     26:  It means that after release 1.2.3, we can release 2.0 if something really big
                     27:  has been made, 1.3 if not that big changes were made or 1.2.4 if mostly bugs
                     28:  were fixed.
                     29: 
                     30:  Bumping, as in increasing the number with 1, is unconditionally only
                     31:  affecting one of the numbers (except the ones to the right of it, that may be
                     32:  set to zero). 1 becomes 2, 3 becomes 4, 9 becomes 10, 88 becomes 89 and 99
                     33:  becomes 100. So, after 1.2.9 comes 1.2.10. After 3.99.3, 3.100 might come.
                     34: 
                     35:  All original curl source release archives are named according to the libcurl
                     36:  version (not according to the curl client version that, as said before, might
                     37:  differ).
                     38: 
                     39:  As a service to any application that might want to support new libcurl
                     40:  features while still being able to build with older versions, all releases
                     41:  have the libcurl version stored in the curl/curlver.h file using a static
                     42:  numbering scheme that can be used for comparison. The version number is
                     43:  defined as:
                     44: 
                     45:         #define LIBCURL_VERSION_NUM 0xXXYYZZ
                     46: 
                     47:  Where XX, YY and ZZ are the main version, release and patch numbers in
                     48:  hexadecimal. All three number fields are always represented using two digits
                     49:  (eight bits each). 1.2 would appear as "0x010200" while version 9.11.7
                     50:  appears as "0x090b07".
                     51: 
                     52:  This 6-digit hexadecimal number is always a greater number in a more recent
                     53:  release. It makes comparisons with greater than and less than work.
                     54: 
                     55:  This number is also available as three separate defines:
                     56:  `LIBCURL_VERSION_MAJOR`, `LIBCURL_VERSION_MINOR` and `LIBCURL_VERSION_PATCH`.
