Version Number)

Version number is the version ID. Each operating system (or software in a broad sense) has a version number. The version number allows you to know whether the operating system is the latest version and the features and facilities it provides. Each version can be divided into the primary version number and the secondary version number. For example, the main version number of dos4.0 is 4, and the minor version number is 0. There are three naming formats for Version Control: 1. GNU version naming format: Main version number. sub-version number [. corrected version number [. build version]: major_version_number.minor_version_number [. revision_number [. build_number] example: 1.2.1, 2.0, 5.0.0 build-13124 II. Windows-style version number naming format: Main version number. sub-version number [corrected version number [. build version]: major_version_number.minor_version_number [revision_number [. build_number] example: 1.21, 2.0 III ,.. NET Framework-style version number naming format: Main version number. sub-version number [. build number [. corrected version number] English comparison: Major_version_number.minor_version_number [. build_number [. revision_number] the version number consists of two to four parts: Main version number, minor version number, internal version number, and revision number. The main version number and minor version number are required. The internal version number and revision number are optional. However, if the revision number is defined, the internal version number is required. All defined parts must be integers greater than or equal to 0. Use these components as agreed below: Major: assemblies with the same name but different major version numbers are not interchangeable. For example, this applies to a large number of product rewriting, which makes backward compatibility impossible. Minor: if the names of the two sets are the same as those of the primary version, but the minor version number is different, this indicates a significant enhancement, but takes care of backward compatibility. For example, this applies to the product's revised version or a new version that is fully backward compatible. Build: different internal version numbers indicate re-Compilation of the same source. This is suitable for changing the processor, platform, or compiler. Revision: The names, major version numbers, and minor version numbers are the same, but the different revision numbers of the Assembly should be completely interchangeable. This applies to fixing security vulnerabilities in previously released assemblies. Only later versions with different internal version numbers or revision numbers are considered as hotfix updates of previous versions. Version Management Policy 1. GNU Version Management Policy: 1. in the initial project version, the version number can be 0.1 or 0.1.0, or 1.0 or 1.0.0. If you are a low-profile user, I think you will choose the primary version number 0; 2. when the project is partially modified or the bug is corrected, the major version number and the sub-version number remain unchanged. The corrected version number is added to 1. 3. when some functions are added to the project on the basis of the original, the main version number remains unchanged, the sub-version number is added with 1, and the corrected version number is reset to 0, so it can be ignored; 4. when the project has been significantly modified or has accumulated a large number of local corrections, resulting in a global change of the project as a whole, the main version number is increased by 1; 5. in addition, the compilation version is generally automatically generated by the compiler during the compilation process. We only define the format and do not manually control the version. ii. Version Number management policy in window: 1. the first version is 1.0 or 1.00. 2. when the project is partially modified or bug fixed, The main version number and the sub-version number remain unchanged. The corrected version number is added to 1. 3. when some functions are added to the project on the basis of the original, the main version number remains unchanged, the sub-version number is added with 1, and the corrected version number is reset to 0, so it can be ignored; 4. when the project has been significantly modified or has accumulated a large number of local corrections, resulting in a global change of the project as a whole, the main version number is increased by 1; 5. in addition, the compilation version is generally automatically generated by the compiler during the compilation process. We only define the format and do not manually control the version. in addition, you can add suffixes such as alpha, beta, gamma, current, RC (Release Candidate), release, and stable after the version number, you can add a version number of one digit after these suffixes. if a user upgrades the main version of a software and wants to continue the software, the company that issues the Software generally charges the user for the upgrade; if the sub-version number or the corrected version number is upgraded In general, it is free.

(Some authors provide registration codes). Currently, this form is rare. Plus is an enhanced version, but most of this type is enhanced on the program interface and multimedia functions. Preview preview edition Corporation & Enterprise Edition Standard Edition mini edition is also called Lite version only the most basic features premium -- Premium Edition professional -- Professional Edition Express -- Special edition Deluxe -- deluxe edition regged -- registered edition CN -- Simplified Chinese edition CHT -- traditional Chinese en -- English multilanguage -- multilingual notes: alpha version indicates that the software is only a preliminary finished product. It is usually only communicated within the software developer, and a few of them are released to professional testers. In general, this version of software has many bugs, and it is recommended that you do not install it. Compared with alpha, beta has greatly improved the version to eliminate serious errors. However, there are still some defects that need to be further eliminated through large-scale release tests. This version is usually released free of charge by software companies and can be downloaded from related sites. Through tests by professional enthusiasts, the results are fed back to developers and developers can make targeted changes. This version is not suitable for general users. The version of Gamma is quite mature, and it is almost the same as the official version to be released. If you can't wait, try it out. Trial (trial version) trial software has been quite popular in recent years, mainly thanks to the rapid development of the Internet. This version of the software usually has a time limit. If you want to continue using it after expiration, you generally have to pay a certain fee for registration or purchase. Some Trial software also imposes certain functional limitations. The Unregistered (unregistered version) unregistered version is very similar to the trial version, but the unregistered version usually has no time limit. In terms of functions, it imposes some restrictions on the official version, for example, there is a big gap in the quality of calls between the registration and unregistered versions of most VOIP software. Some of them are similar to the official version, but an annoying message box will pop up to remind you to register, such as ACDSee and smart Chen Qiao Chinese Character Input Software. The demo version is also known as the demo version. It is the most popular among non-official software. The demo version only integrates several functions in the official version, which is a bit like unregistered. The difference is that the demo version cannot be changed to the official version by upgrading or registering it. The above are the previous versions of the software official version. Alpha, beta, and gamma can be called test versions. There will always be multiple test versions of mature software, such as Windows 98 beta version, there are nearly 10. So many beta versions, on the one hand, try to satisfy the user's needs for the final product, and on the other hand, minimize bugs in the software. Trial, unregistered, and demo are sometimes collectively referred to as the demo version. These versions have a strong color of advertisement and are a bit preemptible. For ordinary users, they can naturally enjoy them for free. The official versions of different types of software are also different. Release this version means "the final release version". After a series of test versions are released, there will eventually be an official version. for users, the software purchased for this version will never be wrong. This version is also known as the Standard Edition. In general, release does not appear on the software cover in the form of words, instead of symbols (R), such as Windows NT (r) 4.0, MS-DoS (r) 6.22. Registered is obviously the registration version opposite to unregistered. The registration and release versions are the same as the standard versions mentioned below. They are all official versions of the software, but a large part of the predecessor of the registration software is downloaded from the Internet. Standard is the most common Standard Edition, No matter what software, the Standard Edition must exist. The standard edition includes the basic components of the software and some common functions to meet the needs of general users. Its price is relatively higher than that of the first-level version. As the name suggests, deluxe is the "deluxe edition ". The deluxe edition is generally compared with the Standard Edition. The main difference is that there are several more features, and the price will certainly be higher than a large one. It is not recommended for general users. This version is usually prepared for professional users who are pursuing "perfection. Reference this version of the model is common in Encyclopedia, more famous is Microsoft's Encarta series. Reference is the highest level. Its subject, image, and video editing have greatly increased compared with standard and deluxe versions, and the capacity has increased from one disc to three, and added strong interaction functions, of course, expensive. That can be said, this version of encyclopedia can be regarded as a real encyclopedia, and it is also the first choice for enthusiasts to collect. Professional (Professional Edition) Professional Edition is for some specific development tools and software. Many of the content in the Professional Edition is not available in the Standard Edition, which is extremely important for a professional software developer. For example, Microsoft's Visual FoxPro Standard Edition does not have the ability to compile into executable files, which is obviously intolerable for a complete development project. It cannot be used without FoxPro on the client. If you use the Professional Edition, there will be no such problem. Enterprise (Enterprise Edition) Enterprise Edition is the best in development software (equivalent to the reference edition in the encyclopedia ). With a set of such software, you can develop any level of application software without any obstacles. For example, the famous visual c ++ Enterprise Edition has added several additional features compared with the Professional Edition, such as SQL debugging, extended stored procedure wizard, and support for AS/400 access to OLE DB. The price of this version is unacceptable to common users. For example, Microsoft's visual studios 6.0 enterprise Chinese version costs 23000 yuan. In addition to the versions described above, other versions also have some proprietary version names. Update (upgraded version) software cannot be used independently. During installation, the software of this version searches for the original official version. If it does not exist, the next step is rejected. Such as Microsoft Office 2000 and Windows 9X. The OEM version is usually bundled in hardware and not sold separately. You can sell your products to other companies to retain their copyright. The two parties will enjoy mutual benefit and win two birds in one fell swoop. The single-host (network) version of the online version is far more complex in terms of functions and structure than the single-host version. if you pay attention to the software quotation, you will find that the prices of some single-host and online versions vary greatly, some online versions require a lot of money to add even more client ports. A popular version is also known as a shared version. It features low price (or even free of charge), a single function, and a strong pertinence (of course, it also takes over the market, combating piracy and other factors ). Different from the trial version, the software of this version generally has no time limit. Of course, if you want to upgrade, you 'd better purchase the official version. The above is a brief introduction to some common software versions. As the software market behavior changes, some new version naming methods have emerged, for example, XP in Windows XP is obtained from the second and third letters in experience. We hope that the above content will help you purchase, use, and download software. Based on commercial considerations, many software do not strictly follow this rule. Microsoft is the most famous. For example, his nt series version. We are familiar with NT 4.0. Windows 2000,200 was launched in 2003, and Windows XP was withdrawn in 1 year. Windows was launched in. At first glance, the differences between the versions are quite large, but they will find that their internal versions are different, in fact, the changes are not big, but the interface changes a lot. This is what software companies often do. Windows 2000 is NT 5.0, Windows XP is NT 5.1, Windows 2003 is NT 5.2, and now longhorn is the real nt 6.0, not sure ). In this way, we can continue to earn money from our customers. After all, people's eyes are the most intuitive, so they feel the most changed.
