| 1 | Sed 3.02 |
|---|
| 2 | |
|---|
| 3 | Fixed a bug in the parsing of character classes (e.g., /[[:space:]]/). |
|---|
| 4 | Corrected an omission in djgpp/Makefile.am and an improper dependency |
|---|
| 5 | in testsuite/Makefile.am. |

| 8 | Sed 3.01 |
|---|
| 9 | |
|---|
| 10 | This version of sed mainly contains bug fixes and portablility |
|---|
| 11 | ehancements, plus performance enhancements related to sed's handling |
|---|
| 12 | of input files. Due to excess performance penalties, I have reverted |
|---|
| 13 | (relative to 3.00) to using regex.c instead of the rx package for |
|---|
| 14 | regular expression handling, at the expense of losing true POSIX.2 |
|---|
| 15 | BRE compatability. However, performance related to regular expression |
|---|
| 16 | handling *still* needs a fair bit of work. |
|---|
| 17 | |
|---|
| 18 | One new feature has been added: regular expressions may be followed |
|---|
| 19 | with an "I" directive ("i" was taken [the "i"nsert command]) to |
|---|
| 20 | indicate that the regexp should be matched in a case-insensitive |
|---|
| 21 | manner. Also of note are a new organization to the source code, |
|---|
| 22 | new documentation, and a new maintainer. |

| 24 | Sed 3.0 |
|---|
| 25 | |
|---|
| 26 | This version of sed passes the new test-suite donated by |
|---|
| 27 | Jason Molenda. |
|---|
| 28 | |
|---|
| 29 | Overall performance has been improved in the following sense: Sed 3.0 |
|---|
| 30 | is often slightly slower than sed 2.05. On a few scripts, though, sed |
|---|
| 31 | 2.05 was so slow as to be nearly useless or to use up unreasonable |
|---|
| 32 | amounts of memory. These problems have been fixed and in such cases, |
|---|
| 33 | sed 3.0 should have acceptable performance. |
